Resistance Tolerance: ±1% (tolerances to ±0.1% available on values of 30 ohms or higher).

Overload/Overvoltage: 5 times rated power with applied voltage not to exceed 1.5 times maximum continuous operating voltage for 5 seconds, AR ±(0.15 percent + 0.01 ohm) max.

Operating Temperature: -55°C to +175°C.

Temperature Coefficient:


	Resistance Range	Temp. Coef.
	Standard : 5 Q and above	50 ppm/°C
	Low : 1 d to 4.99 d	200 ppm/°C

Temperature Coefficient referenced to +25°C, AR taken at -15°C and +105°C.

Insulation Resistance: 10,000 Megohms, minimum.

Measurement Note: Resistance measurement on low resistance values shall be made at a point within 0.2 inch (5.08 mm) of the body.
