IRC Unveils New LRZ Series Jumper Components

The Advanced Film Division of IRC Inc. (Boone, NC), a subsidiary of TT electronics plc, unveiled its new LRZ Series of high-current, low-resistance, cross-over jumper components, which come in three standard chip sizes of 1206, 2010, and 2512 and providing an inductance value of less than 0.2 nH. The component is suitable for many applications, particularly in circuits for power supplies and power amps. Jumper components are often used in circuits involving power audio amplifiers and linear and switching power supplies.

The LRZ Series components are 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 they can be ordered with 60/40 tin lead solder plating and a nickel barrier layer. The LRZ Series chips are compatible with automatic pick-and-place equipment. The 1206, 2010, and 2512 packages have a maximum resistance value of 0.003 Ω and a dielectric withstanding voltage of 200 V. The maximum current for each package ranges up to 20 A, 30 A and 35 A, respectively. The operating temperature for the devices 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.

Pricing for the LRZ Series cross-over jumper components starts at $0.23 in minimum order quantities of 1,000 pieces. Lead time from stock is seven weeks.
