A helical cut is used to adjust the film to its final value. Termination wires are welded to the caps and the resistor is protected with a specially formulated epoxy coating. 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 Dimensions (mm) and Weight (g) PCB Min mounting Bend Wt. Type L Max D Max f min d nom. centres Radius nom. Physical Data LD f d Marking Type reference, TCR code, resistance value and tolerance code. The resistance value marking conforms to IEC 62. Solvent Resistance The body protection and marking are resistant to all normal industrial cleaning fluids suitable for printed circuits. 5(V), 10(T), 15(Y), 25(D), 50(C), 100(Z) See resistance Make Possible Resistors 11.14 General Note TT Electronics reserves the right to make changes in product specification without notice or liability.

Resistors can be supplied matched for tolerance and TCR down to ±0.02% and ±2ppm/°C, either as separate resistors or pre-assembled and encapsulated within a plastic box. The individual resistors within a set or module can be manufactured with a tolerance of ±0.05% and a TCR of ±5ppm/°C.

Based on sampling. 100% screened product is available. 2. For maximum availability, where the ohmic value permits, 25ppm/˚C is preferred to 50 or 100ppm/˚C. 3. For maximum availability, where the ohmic value permits, 0.25% is preferred to 0.5%. Packaging The standard method of packaging RC55P resistors is taped in ammopacks. Taped resistors on reel or loose packed components can also be supplied by special request. In the case of tape packed components the usable lead length is reduced by the width of the tape.
