Crossover Jumper Resistors Have High Current Ratings

The LRZ Series crossover jumper resistors from TT electronics IRC Advanced Film Div. offer designers extremely low resistances as well as a high current ratings. Available in three standard chip sizes, the jumper resistors consist of copper thick film on an alumina substrate, with wrap-around nickel barrier terminations and a protective overcoat covering the jumper element. The resistors are well-suited for power supply and power audio amplifier circuits, including those in consumer applications.

These resistors come in 1206, 2010, and 2512 package sizes. Resistance value is less than 0.003 Ω, with low inductance. Dielectric withstanding voltage is 200 V, and maximum current ratings are 20, 30, or 35 A. The resistors are also qualified to MIL-PRF-32159 standards. In addition, the company can produce devices with specifications to meet specific customer requirements. The LRZ Series is available in both RoHS-compliant and standard Pb/Sn terminations and is compatible with automatic pick-and-place equipment.


Lead time for the LRZ Series 1206 resistors is stock to nine weeks.


The resistors cost $0.18 each in quantities of 10,000 pieces.
