Product Advantages
- Double power density — 2W in a 2512 footprint where standard thick film resistors deliver only 1W, enabling sustained current up to ~1.05A at 1.8Ω without parallel arrangement.
- Stable over wide temperature range — ±100ppm/℃ TCR keeps resistance drift minimal from -55℃ to +155℃; <0.5% shift after 1000h load life at 70℃.
- High surge withstand — tolerates 3W pulse loads for 10 seconds, suitable for motor start/stop and power-up inrush scenarios.
- Cost-effective — thick film process with ±1% tolerance offers significant cost advantage over metal film or alloy current sense resistors while meeting most industrial accuracy requirements.
Typical Applications
- Switching power supplies & DC-DC converters: MOSFET snubber, output current limiting, secondary feedback divider
- Motor drives & VFDs: inverter power stage current limiting and brake circuits
- Battery Management Systems (BMS): cell balancing resistors
- LED drivers: constant-current source sense resistor
- On-board chargers & automotive ECUs: low-voltage auxiliary control loops
- Industrial PLCs & telecom power modules
