Vishay Intertechnology, Inc. of Malvern urges its clients to “build Vishay into your design.”
This spring the Fortune 1000 industrial supplier has released several new products for its automotive, telecommunications, military, aerospace and medical clients to do just that.
First, Vishay has a new universal edgewound power resistor. Providing a convenient drop-in replacement for competing solutions, the universal-mounted EDGU combines a high-reliability design with continuous duty operation up to 85 A and a short-time overload of 10x rated power for five seconds.
The Vishay Milwaukee EDGU features a resistance-alloy ribbon wire that is coiled on edge and supported on specially designed porcelain insulators, which provide proper turn-to-turn spacing and insulation from support bars. The device’s open coil construction allows for efficient heat dissipation and easily accommodates overloads and surges. The EDGU’s terminals are welded to the resistive wire for a reliable electric connection.
Also, Vishay introduced a new Hi-Rel series of TANTAMOUNT® surface-mount solid tantalum molded chip capacitors for military and aerospace applications. Available with high-reliability screening and surge current testing options in accordance with MIL-PRF-55365, the Vishay Sprague T42 series combines a built-in fuse for fail-safe operation with high capacitance and voltage ratings and low ESR down to 80 mΩ at +25 °C and 100 kHz.
The capacitors are ideal for filtering, decoupling and energy storage applications in weapons and radar systems, avionics, and space-based electronics. To protect against catastrophic failures in these safety-critical applications, the devices’ built-in fuse guarantees protection at 5 A for 10 ms and is optimized to ensure activation, while avoiding false triggering.
TheT42 employs a multi-anode “mirror” structure that reduces ESR by at least 50 percent. Each internal anode within the device has a dedicated fuse, allowing unaffected anodes to maintain capacitance in the unlikely event of a failure. Depending on the application, this fault-tolerant design allows for a degraded mode of operation rather than a complete loss of functionality.
Vishay is one of the world’s largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment in diverse industries. Vishay’s product innovations, successful acquisition strategy, and “one-stop shop” service have made it a global industry leader.
