C Series Heatsinks

Ideal type of heatsink for high power density and small size electronic packaging with forced convection cooling

Image of Ohmite's C Series HeatsinksOhmite's C series (patent pending) offers high performance, low cost and a compact heatsink with an integrated camming clip system for TO-126, TO-220, TO-247 and TO-264 devices. This powerful heatsink provides tool and fixture-free assembly operation, along with the largest surface area and smallest space occupation. It is the ideal type of heatsink for high power density and small size (1U or 2U) electronic packaging with forced convection cooling.

Features

  • Designed for general purpose supplies up to 30 W
  • Operates from universal AC mains supplies (80 V to 276 V)
  • Adjustable frequency for flexible design
  • RC oscillator for load insensitive regulation loop constant
  • Valley switching for minimum switch-on loss
  • Frequency reduction at low power output makes low standby power possible(< 100 mW)
  • Adjustable overcurrent protection
  • Undervoltage protection
  • Temperature protection
  • Short-circuit winding protection
  • Simple application with both primary and secondary (opto) feedback
  • Available in DIP8 and SO14 packages
Applications
  • Chargers
  • Adapters
  • Set Top Box (STB)
  • DVD
  • CD
  • TV/Monitor standby supplies
  • PC peripherals
  • Microcontroller supplies in home applications and small portable equipment, etc.
