SWRPxxW TO220 series are high precision and high power resistors encapsulated in the TO-220 package. Power resistors are manufactured in 20W, 25W, 30W, 35W, 50W and 60W. Resistance element is electrically insulated from metal heat sink mounting tab. When properly mounted Semiconwell's SWRPxxW TO220 packaged power resistors provide up to 60 watts of steady state power. These very low inductance resistors are ideal for many industrial applications: power supplies, power controls and inrush/bleeder resistors.
Semiconwell 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.
Semiconwell 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 SWAN04.
