Selection Notes
- Common-mode impedance rises with frequency, so the part is chosen by the band it must suppress.
- Differential-mode noise is not addressed by a common-mode choke alone.
- DCR adds to the supply drop — check it against the current budget.
- Winding capacitance sets how well high-frequency noise is blocked.
- At Optimized DCR DCR, voltage lost across the choke grows with load current.
Typical Applications
Engineers usually specify it for these duties:
- battery
- telecom
- industrial control
- automotive
- DC-DC
