AVX Develops First 0402 Miniature Dual Element AC Varistor
AVX Corp. has expanded its automotive portfolio to include what the company says is the industry’s first miniature 0402-size dual element AC multilayer varistor (MLV). Designed for use in low power ac circuits, the AEC Q200-qualified MAV Series 0402 ac exhibits low insertion loss, unsurpassed EMI/RFI attenuation in the ’off-state,’ and the ability to clamp large transients in a bi-directional manner.
In the ’on state’, the MAV Series varistors feature sub-nanosecond turn-on times that clamp transient energy wave forms well before peak values. The MAV Series varistors can withstand multiple transient strikes, which is critical for use in automotive applications including ac circuits, LC resonant circuits, transformer secondaries and GFI modules.
The MAV Series devices provide superior protection by delivering a 110V peak-to-peak value at 125kHz wave forms when the contact ESD 25kV is superimposed on the human body model (HBM).
"The miniature 0402-size single-element varistors exhibit superior regard for efficiency and safety by combining low-loss characteristics and the ability to handle large amounts of transients with a sub-nanosecond turn-on time that clamps energy before peak, all in the smallest possible package," said Gregg Elliott, AVX global product manager for circuit protection products.
The MAV Series 0402 varistor’s miniature size meets space and weight constraints intrinsic to automotive and harsh environment applications. Also available in 0603 single-element and 0405 dual-element packages, the RoHS compliant devices are AEC Q200 qualified with PPAP documentation available upon request.
Opinion: Unraveling the Ultra-Low Power Design Issues
The MAV Series 0402 varistors have a typical lead time of nine weeks.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
