KOA’s TLR series metal plate current sensing resistors set a new standard for precision and reliability in power electronics. Designed for demanding applications, these resistors offer an ultra-low resistance range from 0.5 mΩ to 20 mΩ, enabling accurate current measurement from 7A - 100A with a TCR as low as 50ppm.
The TLR series employs KOA’s special trimming technique, which delivers two critical benefits:
This precision trimming process also eliminates laser-cut interruptions, improving pulse resistance and ensuring stable performance under transient loads. Combined with resistance tolerances as tight as ±1%, the TLR series guarantees consistent and accurate sensing in high-power circuits.
The TLR series is available in 1206, 2010 and 2512 case sizes with power ratings from 1W to 5W at 90°C to 120°C terminal temperatures (depending on series and resistance value).
The TLR series is AEC-Q200 qualified and are ideal for harsh environments and high-reliability demanded by automotive applications.
