1026R-02H

Fixed Inductors Overview

The Delevan 1026R-02H is a leaded RF inductor from the 1026/R series, designed for high-frequency applications. It features an axial termination style and a molded unshielded construction. The component provides an inductance of 18 nH with a tight tolerance of 3%. It supports a maximum DC current of 420 mA and exhibits a maximum DC resistance of 120 mOhms. Key performance metrics include a minimum Q factor of 28 and a self-resonant frequency of 750 MHz. The physical dimensions are 2.41 mm in diameter by 6.35 mm in length.

Fixed Inductors Feature Summary

• Molded unshielded coil construction for high-frequency stability
• Axial leaded termination for through-hole PCB mounting
• High self-resonant frequency capability up to 750 MHz

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• High-frequency signal processing

Fixed Inductors Procurement Notes

Verify compliance with RoHS and REACH regulations prior to procurement, as status may vary by production batch. Confirm that the specific manufacturing date code aligns with project requirements. Ensure ordering quantities match the factory pack specifications to avoid partial reel handling issues. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and lead times before finalizing supply chain logistics.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 18 nH is required for RF tuning. The unshielded design necessitates careful layout planning to minimize electromagnetic interference with adjacent traces. Verify that the operating frequency remains below the 750 MHz self-resonant point to maintain inductive behavior. Ensure the PCB footprint accommodates the 6.35 mm length and 2.41 mm diameter for proper mechanical clearance.

Fixed Inductors Part Context

This part belongs to the Delevan 1026/R series of RF inductors, which are characterized by molded phenolic cores and axial leads. This series is engineered for reliability in demanding electronic environments. The 1026R-02H specifically targets applications requiring precise, low-value inductance with minimal parasitic effects at VHF frequencies.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include the 1026-02H (non-R suffix) if lead-free terminations are not strictly mandated. Other 18 nH axial inductors from different manufacturers require verification of Q-factor, SRF, and current rating equivalence.
