Ohmite’s Axiohm resistors are

Centohm coated for maximum

reliability. These all-welded

units are characterized by their

low temperature coefficients

and resistance to thermal

shock, making them ideal for

a wide range of electrical and

electronic applications.

• Welded construction

Axiohm Series

• Inorganic and non-hygroscopic,

Centohm coating seals and pro-

tects the resistance wire.

• Exceeds MIL-R-26 moisture

requirements

• Centohm Resistors are designed

to meet and exceed performance

characteristics of vitreous enam-

el resistors.

Centohm Coated

Axial Terminal Wirewound

1.5 in. / 38.1mm

• Centohm is more cost effective

than vitreous enamel.

• ±5% resistance tolerance
