Axial choke
Ferrite-core inductor · 100 µH · DCR 350 mΩ · saturates near 900 mA
Try it on the benchThe lab drops it on an empty bench and opens its datasheet card.
Typical part: Axial RF choke
Pins
- Lead 1
- Lead 2
Ratings and limits
| Inductance | 100 µH |
|---|---|
| DCR | 350 mΩ |
| Saturation | 900 mA |
How to use it
Smooths current in converters and filters noise. Past the saturation current the core stops helping and inductance collapses.
