The value range for Stackpole's CSRF0402 series of metal foil on ceramic current sensing resistors has recently been extended down to 3 milliohms. This is among the lowest resistance values currently available in the 0402 chip size. The CSRF0402 has an operating temperature range of -55C° to +175C°, TCR of 200 ppm, and outstanding power handling capability up to 0.125 W. Higher power versions are also available. The outstanding performance of the CSRF0402 is ideal for a variety of small size portable power and battery management applications, small motor drives, voltage regulators, LED lighting, portable test instruments, portable scanners, and portable power tools.
