14AFR010E

14AFR Current Sense resistors feature a high temperature ceramic body which affords the user higher power densities than similar products which utilize silicone based epoxy molding compounds. The internal 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. SPeCiFiCAtiONS Material Terminals: Solder-plated copper terminals or copper clad steel depending on ohmic value. Encapsulation: Ceramic cased body Derating: Linearly from 4W@70°C to 0W@250°C Electrical 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. Maximum ∆r ∆R
