4302-183G

Fixed Inductors Overview

The Delevan 4302-183G is an unshielded surface-mount RF inductor designed for temperature stability. It features an inductance of 18 µH with a tolerance of 2% and a maximum DC resistance of 11 Ohms. The component supports a maximum DC current of 115 mA and operates within the 1008 (2520 metric) package dimensions. Key electrical characteristics include a minimum Q factor of 20 and a self-resonant frequency of 14 MHz, making it suitable for specific radio frequency applications.

Fixed Inductors Feature Summary

• Provides stable inductance performance across varying thermal conditions
• Utilizes an unshielded construction for standard SMD mounting
• Engineered for high-frequency radio signal processing

Fixed Inductors Applications

• Radio frequency circuit filtering
• Impedance matching networks
• RF signal conditioning modules

Fixed Inductors Procurement Notes

Verify the manufacturer part number against official Delevan documentation to confirm specifications. Ensure compatibility with PCB footprint requirements for the 1008 package size. Check for RoHS compliance status as indicated in current datasheets. Confirm supply chain availability through authorized distributors prior to ordering.

Fixed Inductors Selection Notes

Select this component when a precise 18 µH inductance is required with tight 2% tolerance. Consider the 115 mA current rating and 11 Ohm DC resistance for power handling limits. The 14 MHz self-resonant frequency defines the upper operational limit for effective inductive behavior in the target circuit design.

Fixed Inductors Part Context

This component belongs to the Delevan 4302/R series of fixed RF inductors. The series offers various inductance values in a standardized 1008 surface-mount package. These parts are engineered for consistency in radio frequency environments where thermal stability is critical for maintaining circuit performance.

Fixed Inductors Replacement Considerations

Cross-reference with other 4302-series variants such as 4302-182F or 4302-183F if different tolerance levels are acceptable. Verify that substitute components match the 1008 package dimensions and electrical parameters including inductance, current rating, and self-resonant frequency.
