TO-220 Clip-on Heat Sink (C8 clip-on heatsink black)

Voltage regulators and transistors can get a little hot sometimes! Most chips state that they can cope with high currents and voltage drops, but running these devices in high capacity situations can shorten their life. If you need to protect them from burning out, then add this nifty clip-on heat sink! No screws of thermal paste required, these heat sinks simply slide on to any TO-220 size chip.

These heat sinks have a thermal resistance of 28°C/W when connected to a TO-220 chip, which should let you dissipate around 4 Watts of power.

Technical Specification:

  • Packages Cooled : TO-220
  • Thermal Resistance : 28°C/W
  • External Height : 20mm
  • External Width : 19.7mm
  • External Length : 8.1mm
  • Mounting Type : Vertical / Horizontal clip-on
