IEC 62 colours cement coating applied so that terminations remain are used. completely clear. Solvent Resistance This permits a well defined body length, (clean lead to clean The body protection and marking are resistant to all normal lead dimension L). industrial cleaning solvents suitable for printed circuits. Terminations Flammability Material Solder-coated copper wire. The resistors will not burn or emit incandescent particles under any condition of applied temperature or power Strength The terminations meet the requirements of overload. IEC 68.2.21 Solderability The terminations meet the requirements of IEC 115-1, Clause 4.17.3.2 Performance Data Maximum Load: 1000 hours at 70C R % 5 Shelf life: 12 months at room temperature R % 1 Derating from rated power at 70C R % zero at 155 C Climatic R % 1 Climatic category 40/125/56 Temperature rapid change R % 0.5 Resistance to solder heat R % 0.5 Packaging Application Notes The preferred method of packaging is taped and ammo 1. If the resistors are to dissipate full rate power, it is packed, see figure 1 for critical dimensions. recommended that the terminations should not be soldered closer than 4mm from the body. Alternative packaging is available by special request. 2. Due to operating temperature limitations imposed by some Figure 1 pcb materials, derating may be necessary. An estimate of the temperature rise to be expected can be calculated c using the thermal impedance figures given under Electrical Data. 3. Lead Formed resistors can also be supplied.
