LRZ series cross-over jumper resistors from IRC

TT electronics IRC Advanced Film Division is offering design engineers with an ultra-low resistance device with its new series of crossover jumper resistors. Available in three standard chip sizes, the LRZ series 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.

According to Gary Bleasdell, thick film business unit director for IRC Advanced Film Division, the specifications of the jumper resistors make them suitable for consumer applications. "With its alumina substrate, copper terminations and copper conductor element, the resistor exhibits ultra-low resistance values as well as a high current rating," said Bleasdell. "These features make the resistor ideal for power supply and power audio amplifier circuits, including those in consumer appliances."

The LRZ series jumper resistors are available in 1206, 2010 and 2512 package sizes. Resistance value is less than 3mΩ, with low inductance. Dielectric withstanding voltage is 200V, with a maximum current of 20-, 30- and 35A, respectively. The resistor is also qualified to MIL-PRF-32159 standards. IRC will also produce devices outside these specifications to meet customer requirements.

The LRZ series jumper resistor is available in both RoHS-compliant and standard Pb/Sn terminations, and is compatible with automatic pick and place equipment.

Pricing for the 1206 resistors is Rs.760.86 (18 cents) each in quantities of 10,000 pieces. Lead time is from stock to nine weeks.
