Chip Resistor offers power dissipation up to 3 W at 70°C.September 17, 2007 -
LRF3W Series chip resistor features resistance range from 0.002-0.100W with absolute tolerances of ±1, ±2, ±5, and ±10% and TCR as low as ±100 ppm/°C. With operating temperature range of -55 to +150°C, they are available with leach-resistant wrap-around terminations with tin/lead or lead-free matte tin-over-nickel plating. Devices are suited for high current-sensing applications such as fuel-gauging and over-current detection as well as ac/dc power supplies and VRMs.

IRC's Surface Mount Chip Resistors Feature Low Resistance and High Power Capabilities in Small Package
CORPUS CHRISTI, TX (September 7, 2007) - Providing power electronics design engineers with high power devices for space-constrained applications, TT electronics IRC Advanced Film Division offers a 3W surface mount chip resistor. Designated the LRF3W Series, the chip resistors are offered in a package size traditionally rated at 1W.
"The surface mount resistors, in a 1225 package, have terminations on the long end of the devices, creating a low inductance part and resulting in less stress on the solder joints," said Gary Bleasdell, thick film business unit director for IRC's Advanced Film Division. "The thermal properties of the chip are also much better than traditional designs, allowing it to be rated to 3W as opposed to 1W."
Because of its high power rating in the space-saving package, the LRF3W Series resistor is ideal for high current-sensing applications including fuel-gauging and over-current detection, AC/DC power supplies and VRMs, motorized seats, power windows, seat heaters and automotive fuel pump collision cut-off.
The LRF3W Series chip resistor features a resistance range from 0.002W to 0.100W, with absolute tolerances of ±1%, ±2%, ±5% and ±10%. Power dissipation is up to 3W at 70°C, with TCR as low as ±100ppm/°C. Operating temperature ranges from -55°C to +150°C. The chip resistors feature leach-resistant wrap-around terminations with either tin/lead or lead free matte tin over nickel plating. IRC will also produce devices outside these specifications to meet customer requirements.
Pricing for the LRF3W Series chip resistor is $0.20 at 1800-piece MOQ. Please contact the factory for lead times.
