Ohmite's CSM series heatsinks are suitable for use with multiple TO-220 devices found in active components as well as power resistors. With surface areas ranging from 1,188 mm2 to 6,645 mm2, the CSM family comes in five configurations, all of them with black anodized surface treatment. These heatsinks offer a range of thermal performance from 18 C/W to 9.8 C/W. Each device has solderable-mounting feet and one, two, or three mounting holes are available for convenient device attachment.
