Bradford, Pa. - KOA Speer Electronics has extended the resistance range of its TLRH3AW metal plate chip current sense resistor. The TLRH3AW resistors now offer a resistance range of 10 mΩ ~ 270 mΩ with greater corrosion protection and higher temperature resistance up to +170°C.
The TLRH3AW current sense resistor, based on metal foil technology, allows for a 2-watt power rating in a 2512 package size. Thickness is as low as 0.5 mm. Performance characteristics include a temperature coefficient of resistance (TCR) of ±75 ppm over 10 mΩ~22 mΩ, and ±50 ppm over 24mΩ~270 mΩ, at a 1% resistance tolerance.
The TLRH metal plate chip current sense resistor series also offers power ratings of 0.25W (0805 size) and 1W (2010 size).
The TLRH3AW provides resistance to extreme temperatures, thermal and mechanical shock, moisture and vibration. The TLRH series is AEC-Q200 qualified and is available with lead-free terminations to meet EU RoHS requirements.
The TLRH3AW current sense resistors, used primarily for current detection, are suited for telecommunications and consumer electronics applications, including inverters, power supplies, computing devices, tablets and motor controls.
