Würth Elektronik WE-DCT Toroidal Double Power Chokes
Würth Elektronik WE-DCT Toroidal Double Power Chokes feature coupled inductivity with two identical windings. The ring core double chokes feature very low core losses, very low DC resistance (RDC), and high saturation currents of up to 120A. These chokes are stable, even at high temperatures, and have an operating temperature range of -40°C to +125°C with minimal aging. A special iron powder core material allows the choke to maintain excellent inductance when it undergoes temperature changes and low-level leakage inductance is due to its bifilar winding. Würth Elektronik WE-DCT Toroidal Double Power Chokes are ideal for high-performance switching controllers.
