Current Sense Resistor uses 20 ppm resistance material.

Press Release Summary:




With bare metal element design, BR Series radial leaded thru-hole current sense resistor allows for cooling via airflow, forcing less heat into PCB. It is inherently flameproof, has low typical inductance of 1 nH or less, and exhibits resistance shifts of less than 0.5% and 0.25% for short time overloads. Capable of operating at up to 275ºC, RoHS compliant, lead free resistor is available in 1, 3, and 5 W sizes with TCR ranging from 100-20 ppm depending on resistance value.

Stackpole Electronics, Inc. Introduces the BR Series Bare Metal Current Sense Resistor



Open bare metal element offers low resistance values at low cost ...

RALEIGH, NC (February 11, 2009) - Stackpole Electronics, Inc. announced today the release of the BR Series, a radial leaded thru-hole current sense resistors. The bare metal element design allows for maximum cooling via airflow, forcing less heat into the PCB. The BR Series uses 20 ppm resistance material for outstanding stability over temperature. This series is inherently flameproof and has extremely low typical inductance of 1 nH or less. The product is extremely stable over many hours of life, showing resistance shifts of less than 0.5% and less than 0.25% for short time overloads.

The BR Series is available in 1, 3, and 5 watt sizes with TCR ranging from 100 ppm to 20 ppm depending on resistance value. 1%, 2%, and 5% tolerances are available and resistance values as low as 1 milliohm are possible. The BR Series is also capable of operating temperatures up to 275ºC. These factors make the BR Series an outstanding choice for all types of high current power supplies and power applications requiring a robust part that is impervious to most environmental stresses.

The BR Series is available in bulk packaging in 1000 increments, is RoHS compliant and lead free. Lead time is stock to 8 weeks ARO. Pricing varies by size, resistance value and tolerance, and ranges from $0.20 each to $0.47 each in minimum quantities. Contact Stackpole for volume pricing.
