Stackpole Electronics, Inc. Expands Open Air Metal Shunt Type Current Sense Resistors Down to .002 Ohms
RALEIGH, N.C. (October 31, 2005) - Stackpole Electronics, Inc. has extended the resistance range of its BR Series of current sensing resistors down 0.002 Ohms, in tolerances to ±5%.
The BR Series of flameproof, open air current sense resistors are capable of withstanding 70 amps of current and are rated from 1 to 5 watts at 85ºC, with resistance values now available from from 0.002 ohm to 0.1 ohm. Many BR Series resistance values are available in ±1% tolerances with TCRs as low as +20ppm/ºC. Operating temperature range for the BR Series 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 from stock to 3 weeks.
