AI summary

A 4.7 µH shielded wire-wound power inductor for compact DC power paths, rated at 3.00 A maximum by its thermal-current limit.

Best for

Compact power-conversion stages requiring a shielded 4.7 µH inductor
Consumer, LED-lighting, and telecom electronics within the stated current and temperature limits

Avoid if

A tighter than ±30% inductance tolerance is required
Continuous current exceeds 3.00 A under the applicable thermal conditions

Check before use

Validate inductance under the intended DC bias using application conditions.
Use the recommended 5040 land pattern and verify available height clearance.
Confirm operating temperature remains within -45 °C to +125 °C including self-heating.
