Fixed Inductors Procurement Notes

Verify the specific manufacturer designation as sources list both Sumida America Components Inc. and Sumida Corporation. Confirm RoHS compliance status, as some related series parts may differ. Ensure the 1.2 A current rating aligns with thermal requirements. Check for lead-free availability if required by project specifications.

Fixed Inductors Selection Notes

Select this component for applications requiring radial leaded power inductors with moderate current handling. Compare against the RCH110NP series for higher current ratings or different temperature ranges. Verify that the unshielded nature does not interfere with nearby sensitive components on the PCB layout.

Fixed Inductors Part Context

This part belongs to the RCH110B series of power inductors designed for through-hole technology. It complements other variants like the RCH110BNP-331K and RCH110B-271KB within the same product family, offering consistent mechanical dimensions while varying electrical characteristics such as inductance and saturation current.

Fixed Inductors Replacement Considerations

Direct substitutes include other Sumida radial inductors from the RCH110 series with matching 150 µH values. Cross-reference with generic radial power inductors ensuring identical footprint (5 mm spacing) and current capacity.
