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.

Application Notes
1. If the resistors are to dissipate full rate power, it
is recommended that the terminations should not be
soldered closer than 4mm from the body.
Sample Part No.

Value
2. Due to operating temperature limitations imposed
by some pcb materials, derating may be necessary. An
estimate of the temperature rise to be expected can be
calculated using the thermal impedance figures given
under Electrical Data.
