105-332H

Overview

The Delevan 105-332H is a fixed RF inductor designed for surface-mount technology applications. It features a nominal inductance of 3.3 µH with a tight tolerance of ±3%. The component utilizes a ferrite core and is constructed as an unshielded unit, suitable for general-purpose RF circuits. It exhibits a maximum DC resistance of 2.2 Ohms and supports a maximum DC current of 210 mA. Key electrical characteristics include a minimum Q factor of 25 and a self-resonant frequency of 62 MHz. The physical dimensions are standardized at 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height, utilizing standard SMD/SMT terminations.

Feature Summary

• Unshielded construction using ferrite core material for RF signal handling
• High precision inductance stability with ±3% tolerance rating
• Optimized quality factor (Q) and self-resonant frequency for RF circuit integration

Applications

• RF inductor circuits
• Surface mount PCB assembly
• General purpose inductive filtering

Procurement Notes

Verify the specific manufacturing lot and compliance documentation upon order confirmation. Confirm that the unshielded configuration aligns with the electromagnetic interference requirements of the target design. Ensure the selected package style matches the automated placement equipment capabilities. Review the official datasheet for any recent updates regarding material composition or testing standards prior to final procurement authorization.

Selection Notes

Select this component when a precise 3.3 µH value is required in a compact non-shielded form factor. The 210 mA current rating dictates suitability for low-power RF stages rather than high-current power supplies. Compare the 2.2 Ohm DC resistance against voltage drop constraints in the signal path. Consider the 62 MHz self-resonant frequency limit to ensure operation remains within the desired bandwidth without parasitic resonance effects.

Part Context

This part belongs to the Delevan fixed inductor family, specifically categorized under RF inductors. It shares the 3.3 µH inductance value with other variants like the 105-332HS but differs in shielding and tolerance specifications. The 105 series represents a standard line of chip inductors intended for high-frequency applications where size and precision are critical design parameters.
