Overview
The Coilcraft DR0810-682L is a robust wirewound power inductor designed for demanding DC-DC converter and power filtering applications. Its key operational characteristic is the high saturation current of 7.4A, enabling it to handle significant current transients without significant inductance derating. A critical design consideration for this unshielded ferrite core inductor is its relatively low self-resonant frequency (SRF) of 26 MHz; engineers must carefully consider this when designing circuits operating at or above this frequency to avoid unwanted parasitic resonance and ensure stable operation, especially in high-frequency switching power supplies.
Key Features
- Inductance: 6.8 µH
