ETD Bobbins
ETD bobbins for round centre leg ETD cores used in higher power converters.
What This Series Covers
ETD bobbins for round centre leg ETD cores used in higher power converters. There are 13 published part numbers, and every one lists the plastic, the pin count and the pin geometry where the drawing states them.
If a geometry in this series is close but not exact, the tool room can modify pin counts, section splits and mounting features on a new tool rather than forcing a redesign around a stock part.
