TECHNOLOGY

The resistor element is a resistive wire, which is wound, on ceramic rod.

Tinned copper leads are connected to the caps by welding. The resistor body are housed in a rectangular ceramic case with a

special inorganic potting which is non-flammable, will not melt even at high overloads and is resistant to most commonly used

cleaning solvents and moisture.

Notes:

(1) Special resistance values available upon request

(2) Other tolerances available upon request

Note:

(3) Temperature Coefficient of ± 30, 50 or 90 ppm/ºC available upon request
