The PF2272 non-inductive, thin film power resistor series from Riedon offers all E12 resistance values in the range between 0.1Ω and 1MΩ, plus 2Ω and 5Ω, with a power rating of 200W. They offer a standard tolerance of 5%, with 1% available upon request, and a TCR as low as ±100 ppm/°C. The PF2272 power thin film resistors come in a standard TO-227 housing with an isolated back plate and M4 x 5mm screws included, and are available in three different terminal configurations. They require mounting on a suitable heat sink (please see the datasheet for calculations).
