TO-220, TO-247 POWER RESISTORS |
|
TO-220, TO-247 Power Resistors RMG series are ultra precision and high power resistors encapsulated in the TO-220/TO-247 style power package. Power resistors are manufactured in 20W, 30W, 35W, 50W and 100W. Resistance element is electrically insulated from metal heat sink mounting tab. When properly mounted DIRECT's RMG** TO-220/TO-247 packaged power resistors provide up to 50/100 watts of steady state power. These very low inductance resistors are ideal for many industrial applications: power supplies, power controls and inrush/bleeder resistors. DIRECT thin film power resistors are manufactured by depositing continuous and defect free metallic films conferring long-term stability, very low TCR, very low current noise and negligible non-linearity. DIRECT thin film power resistors are price competitive while outperforming the thick film power resistors currently used in high power applications. For more info as how thin film resistors compare with thick film resistors, see FCR, RCA, RCN. |
