Stackpole Electronics, Inc. Introduces Metal Resistor Technology for Current Sense Applications
Open Air Design Allows for Cooler Operation...
RALEIGH, N.C. (March 10, 2005) - Stackpole Electronics, Inc. has introduced a new flameproof, open air current sense resistor technology ideally suited for high current motor control and power regulation applications.
Designated the BR Series, these current sense resistors are capable of withstanding 70 amps of current are rated from 1 to 5 watts at 85ºC with resistance values from 0.005 ohm to 0.1 ohm and tolerances down to ±1 percent. They feature TCRs as low as +20ppm/ºC. Operating temperature range is -40ºC to +125ºC.
The BR Series of resistors features a resistive element with a unique off the board design that keeps the resistor's "hot spot" safely off the PC board and allows air to circulate around it, contributing to cooler operation.
Applications for the BR series include: large portable electronics, power supplies, servers, satellite communications, window lift and sunroof motors, wiper controls, power steering systems and anti-lock braking systems. The BR Series is typically used in current sense, feedback and surge protection circuitry.
Typical pricing for the BR Series of resistors is approximately $.15 in quantities of 5,000, with delivery times 6 of 8 weeks. Samples of standard products are available immediately.
