Encapsulation Ceramic cased body Derating Linearly from 4W@70°C to 0W@250°C Max.Voltage √(PxR) RMS Climatic Category 55/200/56 TCR Varies from +150 to +1100ppm/°C based on resistance value. TCR increases as resistance value reduces from 51 to 4milliohms. TCR is tested as per IEC Specification 115-1 Clause 4.8.4.2 Tolerance ±1% standard. Others available. Power rating 4W@70°C Dielectric withstanding voltage 1000 VRMS for 3 and 5 watt; 500 VRMS for 2 watt. Insulation resistance Not less than 1000MΩ. Thermal EMF Less than ±2µV/°C. Temperature range -55°C to 275°C. 14AFR Current Sense resistors feature a high tem- perature ceramic body which affords the user higher power densities than similar products which utilize silicone based epoxy molding compounds. The inter- nal construction involves a straight, low inductance, 3-piece welded metal element at 1% tolerance. This series is stocked in 9 popular resistance values for easy accessibility.
