Riedon PF2276 Series

The PF2276 non-inductive, thin film power resistor series from Riedon offers all E12 resistance values in the range between 50Ω and 1kΩ, plus 2Ω and 5Ω, with a power rating of 600W. They offer a standard tolerance of 5% (1% available on request) and a TCR as low as ±100 ppm/°C. These thin film power resistors come in a standard TO-227 housing with 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 (see datasheet for calculations).

• Power rating of 600W with heat sink (5W without heat sink)
• Resistance range 50Ω to 1kΩ, nominal E12 plus 2Ω and 5Ω
• Inductance as low as 14nH
• Standard tolerance ±5%, ±1% available upon request
• Thermal resistance as low as 0.11°C/W
• TCR of ±100 ppm/°C
• Temperature range −55°C to +155°C
• TO-227 housing
• Isolated back plate
