Fixed Inductors Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm exact tolerances and packaging configurations. Ensure that the selected variant meets the required RoHS compliance status for your assembly process. Cross-reference the DigiKey or Mouser part numbers to confirm availability and standard delivery times prior to finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when a 56 µH inductance with ±10% tolerance is required for RF applications. Consider the 130 mA current rating and 3.4 Ohm DCR limits to ensure compatibility with circuit power constraints. Verify that the unshielded nature does not interfere with nearby sensitive components due to potential magnetic field radiation.

Fixed Inductors Part Context

This component belongs to the 1025R series of fixed RF inductors manufactured by Delevan. The series utilizes molded techniques with iron cores to achieve consistent electrical characteristics across various inductance values. These inductors are engineered for reliability in demanding electronic environments.

Fixed Inductors Replacement Considerations

Equivalent parts may include other 56 µH axial lead inductors from manufacturers such as API Delevan or Coilcraft, provided they match the 130 mA current rating and physical dimensions. Verify that substitute components offer comparable self-resonant frequencies and Q values for RF integrity.
