Application Notes
1. If the resistors are to dissipate full rated power, it is recommended that the terminations should not be soldered
closer than 4mm from the body.
2. Due to operating temperature limits 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. To protect against fire under all conditions of overload, a positive clearance of at least 13mm should be provided
between the body of the resistor and any combustible materials.
3. EMC resistors can also be supplied loose packed with radial, goalpost or lancet pre-formed leads, tape packed with
radial pre-formed leads, or in blister tape with Z-formed leads for SMD mounting. Consult factory for details.
Packaging
Our standard packaging for EMC is taped and boxed. The critical dimensions are shown in Figure 1. The component
wires will not protrude beyond the outside edge of the tapes. Alternative packaging is available by request.
