This permits a well defined body length, (clean lead to clean lead dimension L). Terminations Material Strength Solderability Solder-coated copper wire. The terminations meet the requirements of IEC 68.2.21 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.

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. 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. 3. Lead formed resistors can also be supplied. Standard options of Lancet, Radial, and Goalpost forming are shown in lead Form Information section.
