New Yorker Electronics is distributing the new Vishay direct water-cooled power wirewound resistor (WCR) for high-power applications. Available in seven different lengths, the Vishay Super 12 featured product saves space by reducing the number of components required to dissipate heat.
By providing direct liquid cooling without the need for a heatsink and multiple resistances, the Vishay MCB device from New Yorker Electronics also saves on assembly costs. The WCR makes a direct connection to the

The Vishay direct WCR is optimized as a snubber and DC grading resistor for large drives, high voltage inverters, rectifiers and high voltage DC transmission systems/static VAR compensators.
The WCR offers very high power dissipation up to 2500 W at 60° C water inlet temperature and tolerates high pulses up to 5000 W for 10 s. It features a resistance range from 4.7 Ω to 56k Ω with a ±5% tolerance, a temperature coefficient of 100 ppm/° C, and a maximum working voltage to 3500 V, with 6600 V available upon request.
The RoHS-compliant device offers a non-inductive option below 25 0nH and operates over a temperature range of -55° C to 120° C. Typical applications for the device include snubber, permanent discharge, balancing and filtering. New Yorker Electronics also offers the option for multiple resistors.
New Yorker Electronics is a franchise distributor for Vishay and supplies its full line of discrete semiconductors (diodes, MOSFETs and infrared optoelectronics) and passive electronic components (resistors, inductors and capacitors).
