55 Watt Thermal Surface-Mount Resistor - TKH55 Series
Designed to replace any TO-263 package. The TKH55 is rated at 55 watts with a thermal resistance of 3.0°C/W in a surface-mount design capable of high wattage dissipation with the proper heatsink and thermal considerations. The Ohmite D series heatsinks with the TKH55 presents a complete solution for your surface-mount wattage requirements. The thick film construction enables non-inductive performance and is suited for precharge and snubber applications. Other key design features include:
- Elimination of multiple thermal layers including a metal header for greater thermal performance.
- SMD shares same land pattern as TO-263 with a low profile
- Up to 55 watts of power dissipation
- Larger resistance area promoting higher energy and greater thermal performance
- Elimination of wire bonds for greater reliability
- Use Ohmite D Series heatsinks for maximum performance
