Achieving 25W high power with surface mount on the substrate! SMD resistors that adopt a metal tab D-Pak package, balancing high-density mounting and excellent heat dissipation.
D-Pak Resistors Enabling Space-Saving and High Power for Surface Mount Circuit Boards
The 'MP725' from Cadock, USA, is a surface mount power film resistor in the D-Pak (TO-252) style, widely used in power transistors and other applications.
**Main Features**
- High Heat Dissipation: The metal tab on the bottom assists in efficient heat dissipation to the circuit board, supporting up to 25W of high power at a case temperature of 25°C.
- Improved Solderability: The metal tab is exposed externally, making visual inspection after reflow mounting easy.
- Current Detection Compatible: Offers ultra-low resistance values starting from 0.020Ω, ideal for current detection circuits in power supplies.
- Completely Inductance-Free: Reduces noise in high-frequency applications such as switching power supplies, snubber circuits, and RF devices.
