1026R-04H

Fixed Inductors Overview

The Delevan 1026R-04H is a fixed axial leaded RF inductor designed for general-purpose applications. It features a molded unshielded coil construction with a phenolic core material. The component provides a nominal inductance of 0.033 µH (33 nH) with a tolerance of 2%. It exhibits a maximum DC resistance of 0.035 Ω and supports a maximum DC current of 2 A. Key performance metrics include a minimum Q factor of 40 at 25 MHz and a self-resonant frequency of 850 MHz. The device operates within a temperature range of -55 °C to +125 °C and utilizes standard axial terminals.

Fixed Inductors Procurement Notes

Verify the specific suffix against official API Delevan documentation, as variations such as the 1026R-04J exist with different tolerances. Confirm that the required 2% tolerance aligns with the 04H designation rather than other series variants. Ensure the axial lead length and diameter meet PCB layout requirements before finalizing procurement specifications.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-frequency solution is required for through-hole assembly. The unshielded design necessitates careful placement to minimize electromagnetic interference with adjacent components. Verify that the 2A current rating satisfies the peak load requirements of the target circuit without causing saturation or excessive heating.

Fixed Inductors Part Context

This part belongs to the 1026/R series of fixed inductors manufactured by API Delevan. The series is characterized by molded unshielded coils intended for radio frequency applications. It shares structural similarities with other axial inductors in the lineup but is distinguished by its specific low inductance value and tight tolerance specifications for precision RF tuning.

Fixed Inductors Replacement Considerations

The 1026R-04J is a documented variant within the same series. Note that the J suffix typically indicates a 5% tolerance compared to the 2% tolerance of the H suffix. Substitution requires verification that the looser tolerance meets the circuit's performance criteria.
