Type FRN Series

The resistive element comprises a

resistive film sputtered onto a ceramic

element. Metal end caps are force

fitted to the element prior to spiralling.

Tinned copper lead wires are welded to

the end caps and the components are

then coated with four layers of a flame-

proof cement. All resistors are tested

for value and tolerance. The technology

allows the manufacture of custom

fusible characteristics.

Key Features

■

Literature No. 1773218

Issued: 10-08

Superior quality

resistors with fusing

characteristics for

overload conditions.

Flame-proof during

fusing.

Ideal for use in safety-

critical and circuit

protection applications.

These resistors fuse in

less than 60 seconds at

16 times rated power.
