Jumpers Combine High Current With Ultra Low Resistance

Primed for use in power audio amplifiers and linear and switching power supplies, the LRZ Series of cross-over jumpers features a maximum current of 35A at a resistance of 0.003O and inductance of less than 0.2 nH. The components come in three standard chip sizes of 1206, 2010 and 2512. Constructed using a thick copper layer on an alumina substrate with a protective overcoat covering the jumper element, the devices are available in RoHS compliant versions or can be ordered with 60/40 tin lead solder plating and a nickel barrier layer. Compatible with automatic pick and place equipment, the packages have a dielectric withstanding voltage of 200V. Maximum current for the 1206, 2010 and 2512 packages range up to 20A, 30A and 35A, respectively. Operating temperature is -65°C to 150°C. All jumpers in the LRZ Series have been tested for environmental performance, short time overload, high temperature exposure, moisture resistance and low temperature operation. Typical pricing starts at $0.23 each/1,000. Lead time from stock is seven weeks. IRC Inc., Corpus Christi, TX. (361) 992-7900.
