Newark, the Development Distributor, announced today the availability of Infineon's MERUS™ Class D audio amplifier solutions, which use pioneering multilevel switching technology to increase audio performance and reduce power loss during operation. Infineon's enhanced design and production standards deliver extreme reliability and stability for the entire product lifetime. The new range offers improved power efficiency, decreased size, weight and electromagnetic interference, and lower overall cost than traditional solutions on the market.

Electronics engineers can use MERUS™ Class D audio solutions in a variety of applications such as battery-operated speakers, wireless and docking speakers, soundbars, multi-room systems and home theater systems. The MERUS™ portfolio includes fully integrated monolithic audio amplifier ICs, multi-chip audio amplifier modules (MCMs), as well as discrete audio amplifier driver IC and power MOSFET solutions, scalable to meet the most stringent and demanding application needs.

The products now available from Newark include:

• The MA12040P (for 4-18V supply voltage range) and the MA12070P (for 4-26V supply voltage range), suitable for battery operated speakers, wireless and docking speakers, soundbars and multi-room/home theater systems. Both feature an embedded digital power management scheme with an algorithm that dynamically adjusts switching frequency and modulation to optimize power loss and EMI across the output power range. Integrated digital-to-analogue converters enable digital I2S audio stream input. The amplifiers support sample rates from 44.1 kHz to 192 kHz and offer protection against DC, short circuits, over-temperature and under-voltage situations. Flexible "power mode profiles" allow the user to utilize the multilevel switching technique for very low power loss or very high audio performance. Also available, for Analog input, are the complementary MA12040 and MA12070.

• The EVAL_AUDIO_MA12070P easy to use audio evaluation kit contains all the elements needed to evaluate the highly power-efficient MERUS™ digital input multilevel class D amplifier 2╫80W (MA12070P). The IC is specifically targeted for high-performance filter-less and heatsink-free audio applications and suitable for applications such as voice controlled audio and professional audio where it is essential to maximize dynamic range and audio performance while minimizing power dissipation and power loss.

Lee Turner, Global Head of Semiconductors and Single Board Computing, at Newark said: "Infineon is known for its pioneering solutions for audio application requirements delivered through patented architectures, proprietary algorithms, advanced manufacturing technologies, and extensive verification and testing. The MERUS™ amplifier solutions, now shipping from Newark, provide customers with an unprecedented sound experience, designed to maximize power efficiency while providing best-in-class audio performance in optimal-fit form factors suitable for design engineers developing products for both home or professional use."

"With recent technological innovations, such as multilevel class D amplifiers, which are designed specifically for superior audio quality and power efficient amplification of music signals, designers are enabled more than ever to create better products for their customers. We are delighted by Newark's support in raising awareness and distribution of our future-proof MERUS™ audio-amplifier ICs," said Jens Tybo Jensen, Head of Class D Audio, at Infineon Technologies.

Infineon's MERUS™ range of Class D audio amplifier solutions are available from Newark in North America, Farnell in EMEA, and element14 in APAC.

Hamilton Caster Appoints Andrew D. Stamp as Director of Sales

Hamilton Caster & Mfg. Co., a 117-year-old industry leader in heavy-duty industrial casters, proudly announces the enhancement of its legacy Super Endurance Caster (SEC) series, now rebranded as the Spinfinity® Super Endurance Caster (ZFSEC) series. In addition, Hamilton is introducing the all-new Spinfinity® Super Endurance Dual Caster (ZFSEC2) series, both of which feature a new heavy-duty 'V-Style' seal designed to elevate performance in the most demanding environments.
The Spinfinity® Super Endurance Caster (ZFSEC) series replaces Hamilton’s legacy SEC series, setting a new benchmark for kingpinless caster design in extra heavy-duty applications. Central to this upgrade is the heavy-duty 'V-Style' seal, which offers protection against dirt, debris, and moisture. This advanced sealing technology ensures consistent performance and extends the life of the caster, making it the ideal choice for environments where reliability is critical.
"With the introduction of the V-Style seal, the ZFSEC series is engineered to withstand the harshest conditions while providing zero-fix, 100% maintenance-free operation," said Mark Lippert, president of Hamilton Caster. "This enhancement allows our customers to minimize maintenance costs and downtime, further solidifying Hamilton’s reputation for durability and dependability."
The ZFSEC series retains the robust construction that Hamilton is known for, including a swivel top plate and inner raceway made from forged steel, providing superior strength for shock conditions. Sealed precision ball bearings are also now standard in all wheels, contributing to the maintenance-free performance of the series. Notably, the zerk fittings have been eliminated, as the new design makes them unnecessary.
Complementing the ZFSEC series, Hamilton introduces the all-new Spinfinity® Super Endurance Dual Wheel Caster (ZFSEC2) series. This dual wheel series is engineered for extra heavy-duty applications where stability, durability, and maintenance-free operation are paramount. Like its counterpart, the ZFSEC2 series leverages the new 'V-Style' seal, ensuring that each caster is fully protected against contaminants that could compromise performance.
Combined with sealed precision ball wheel bearings, this caster series ensures zero-fix, 100% maintenance-free performance. The dual-wheel configuration enhances stability and allows for a lower overall height, offering a perfect blend of strength and maneuverability.
Casters in both series are finished in a durable HAA polyester platinum powder coat and are available in a wide variety of wheel types, allowing for customization based on application needs. For complete wheel specs and product details check out the Spinfinity® Super Endurance Caster Landing Page and all-new Spinfinity® Super Endurance Dual Caster Landing Page.

New Horizon Releases Innovative Functionality for Optimizing Inbound Logistics Scheduling at DCs

ACTON, Massachusetts – September 3, 2024 – New Horizon Soft, LLC (https://www.newhorizon.ai), a global leader in AI-powered supply chain planning software, announced today the release of a new version of its Buyers Workbench procurement planning software. The latest version includes the ability to optimally schedule inbound deliveries, taking into account distribution center (DC) receiving capacity, thus minimizing receiving bottlenecks and lowering inbound logistics costs. A research paper describing the innovative methodology and its deployment at an iconic $10B+ U.S. quick-service restaurant chain was recently published in the peer-reviewed academic journal, the International Journal of Operations Research and Information Systems.

Supply chain organizations typically plan purchase orders without regard to DC receiving capacity. This leads to bottlenecks on some days and underutilized staff on others. New Horizon’s methodology, called Master Purchasing Receipt Scheduling (MPRS), uses a novel algorithm to automatically and optimally schedule deliveries. The algorithm plans deliveries at the time of purchase order creation and results in a steady volume of deliveries and lower planning and logistics costs. While first deployed at a restaurant chain, the methodology is applicable to any manufacturer, wholesaler, retailer, or foodservice company operating high-velocity DCs.
