1.1

Construction

The resistance element is a precisely controlled thin film

of metal alloy on a high purity ceramic core, protected

by a cement coating applied so that terminations remain

completely clear.

This permits a well defined body length, (clean lead to

clean lead dimension L).

Terminations

Material

Solder-coated copper wire.

Strength

The terminations meet the

requirements of IEC 68.2.21

Solderability

The terminations meet the

requirements of IEC 115-1,

Clause 4.17.3.2

Marking

MF Series resistors are color coded with 4 bands. IEC 62

colors are used.

Solvent Resistance

The body protection and marking are resistant to all normal

industrial cleaning solvents suitable for printed circuits.

Flammability

The resistors will not burn or emit incandescant particles under

any condition of applied temperature or power overload.
