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
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.
