4302R-222J

Fixed Inductors Overview

The Delevan 4302R-222J is a surface-mount RF inductor from the 4302/R series, designed for temperature-stable performance. It features an inductance of 2.2 µH with a ±5% tolerance and a maximum DC resistance of 1.25 Ohms. The component supports a maximum DC current of 345 mA and achieves a minimum Q factor of 30 at its self-resonant frequency of 50 MHz. Housed in a compact 1008 (2520 metric) package, it utilizes an unshielded wirewound construction with a ferrite core, operating within a temperature range of -55°C to +125°C.

Fixed Inductors Feature Summary

• Temperature-stable design suitable for precision RF applications
• Unshielded wirewound construction for specific circuit requirements
• Compact 1008 surface-mount footprint for space-constrained PCBs

Fixed Inductors Applications

• RF signal filtering circuits
• Impedance matching networks
• General-purpose radio frequency choke applications

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as some sources list API Delevan while others reference Delevan directly. Confirm RoHS compliance status through official documentation, as availability varies across distributors. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel quantities, prior to finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a stable 2.2 µH inductance is required in a small SMD form factor. The unshielded design necessitates careful layout consideration regarding electromagnetic interference. Verify that the 345 mA current rating meets the application's peak load requirements and that the 1.25 Ohm DCR aligns with power loss constraints.

Fixed Inductors Part Context

This part belongs to the 4302/R series of fixed RF inductors manufactured by Delevan. The series is characterized by temperature-stable performance and unshielded construction, targeting high-frequency electronic applications. It serves as a specialized passive component within the broader category of surface-mount inductors and chokes.

Fixed Inductors Replacement Considerations

Direct substitutes include the 4302-222F for tighter tolerance requirements and the 4232R-222H for alternative physical dimensions. Cross-reference electrical parameters carefully, particularly DC resistance and self-resonant frequency, to ensure functional compatibility in existing designs.
