Fixed Inductors Procurement Notes

Verify the specific suffix 'L' against official Sumida documentation to confirm lead-free compliance and exact electrical tolerances. Ensure the procurement channel provides valid traceability for the active part status. Cross-reference the 100 kHz test frequency requirement with system specifications to guarantee accurate inductance validation during integration.

Fixed Inductors Selection Notes

Select this component when a 560 µH inductance value is required for through-hole assembly processes. The 640 mA current rating suits moderate power levels, while the 1.125 Ohm resistance impacts efficiency calculations. Consider the unshielded nature for layout planning to manage potential electromagnetic interference in sensitive adjacent circuits.

Fixed Inductors Part Context

This model belongs to the RCH8011 series of fixed power inductors manufactured by Sumida America Components Inc. The series is characterized by radial leads and vertical cylinder packaging, designed specifically for robust through-hole applications.
