Welwyn Components Limited Bedlington, Northumberland NE22 7AA, UK Flameproof Power Flameproof Power Metal Film Resistors Metal Film Resistors MFP Series Welwyn Components MFP Series Performance Data Maximum Load at rated power : 1000 hours at 70C R % 5 Shelf life : 12 months at room temperature R % 2 Derating from rated power at 70C R % zero at 155C Climatic R % 3 Climatic category 50/155/56 Temperature rapid change R % 0.5 Resistance to solder heat R % 0.5 Voltage proof volts 500 min Packaging Application Notes MFP resistors are normally supplied tape packed ready for 1. If the resistors are to dissipate full rated power, it is loading onto automatic sequencing and insertion machines. recommended that the terminations should not be soldered closer than 4mm from the body. The standard taping method and critical dimensions are shown in Figure 1. 2. Due to operating temperature limitations imposed by some pcb materials, derating may be necessary. An estimate of Component wires will not protrude beyond the outside edge the temperature rise to be expected can be calculated of the tapes. using the thermal impedance figures given under Electrical Data. Alternative packaging available by request. 3. These products are also available in a range of lead forming options. In particular, MFP2 is available in ZI-form SMD format packed in blister tape - see:
