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. Type reference, TCR code, resistance value and tolerance code. The resistance value marking conforms to IEC 62. The body protection and marking are resistant to all normal industrial cleaning fluids suitable for printed circuits. Terminations Material Strength Solderability Solvent Resistance 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 Performance Data Values 10 ≤ 250k Values > 250k Actual Performance Actual Performance Maximum Typical Maximum Typical 0.02 0.25 0.05 Load at rated power : 1000 hrs at 70°C (or 85°C) ∆R % 0.05 Dry heat : 1000 hrs at 155°C ∆R % 0.15 0.08 1 0.2 Shelf life : 12 months at room temperature ∆R % 0.01 0.003 0.04 0.02 Derating from rated power at 70°C (or 85°C) Zero at 155°C Zero at 155°C Short term overload ∆R % 0.01 0.001 0.08 0.01 Climatic ∆R % 0.05 0.02 0.2 0.05 Long term damp heat ∆R % 0.05 0.02 0.2 0.05 Temperature rapid change ∆R % 0.04 0.02 0.25 0.05 Resistance to solder heat ∆R % 0.02 0.003 0.05 0.005 Vibration and bump ∆R % 0.02 0.002 0.06 0.02 Noise (in a decade of frequency) µV/V 0.2 0.03 1 0.1 Voltage coefficient of resistance ppm/V 0.3 <0.05 0.2 <0.05 Climatic category 55/155/56 Application Notes 55/155/56 Figure 1 Resistors can be supplied matched for tolerance and TCR down to ±0.005% and ±1ppm/°C, respectively, either as separate resistors or pre-assembled and encapsulated within a plastic box.
