Product Overview
Pulse Electronics P1967L is a heavy-duty toroidal power inductor designed for power conversion and filtering applications. Built with six turns of heavy enameled copper wire wound over an 18 mm blue toroidal core, this open bare-coil design provides low DC resistance and high current capability for switch-mode supplies and output choke duty.

Applications
- Output filtering in switch-mode power supply builds and repairs
- DC-DC buck and boost converter stages
- High-current DC ripple suppression and power smoothing
- Custom audio power supply and amateur radio RF choke circuits
Frequently Asked Questions
Is there polarity to observe when installing this inductor?
No. This toroidal inductor is non-polarized and functions identically in either orientation in a circuit.
What mounting configuration do the wire leads use?
The leads extend radially from the bottom of the coil, pre-tinned for direct through-hole printed circuit board mounting or terminal strip soldering.
Six turns of heavy copper on a blue toroid, built for circuits where current does real work. Solder it in, clean the board, and let the power flow.
