The limiting factor insofar as the resistor is concerned is the film temperature. This should not exceed + 200 °C and for maximum stability should not exceed + 150 °C. Type designation resistance value, tolerance and code date of manufacture are printed on each unit. All types electroplated copper except SPW-212. The SPW-212 has silver coated termination bands.
