RL-7500-2-220M

Fixed Inductors Overview

The RL-7500-2-220M is a fixed shielded drum core wirewound inductor manufactured by Renco Electronics, Inc. It features a nominal inductance of 22 µH with a tolerance of ±20%. The component supports a maximum current rating of 2.8 A and exhibits a maximum DC resistance of 36 mΩ. Designed for surface mount applications, it utilizes a nonstandard package configuration suitable for high-current power supply circuits.

Fixed Inductors Feature Summary

• Shielded drum core construction minimizes electromagnetic interference
• Wirewound design ensures stable performance under load
• Surface mount format facilitates automated assembly processes

Fixed Inductors Applications

• DC-DC converter input filtering
• Power supply output stages
• High-current signal processing circuits

Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm package dimensions and tape/reel specifications. Confirm that the 18-week standard lead time aligns with project schedules. Ensure the RoHS status meets environmental compliance requirements for the target market. Cross-reference the nonstandard package outline against PCB footprint designs prior to procurement.

Fixed Inductors Selection Notes

Select this component when a 22 µH inductance value is required with a minimum 2.8 A current handling capability. The low DC resistance of 36 mΩ makes it suitable for efficiency-critical power paths. Consider the shielded drum core geometry for applications requiring reduced magnetic field leakage compared to unshielded alternatives.

Fixed Inductors Part Context

This part belongs to the RL-7500 series of shielded high-current SMD power inductors from Renco Electronics. The series offers various inductance values and current ratings within similar physical footprints. The '2' in the model number typically denotes specific winding or core variations within the product family line.

Fixed Inductors Replacement Considerations

Direct substitutes include other RL-7500 series variants such as RL-7500-2-270M for different inductance needs. Verify pin compatibility and thermal characteristics before swapping. No alternative manufacturer equivalents are confirmed in public documentation.
