ELJ-QE27NGFA

Fixed Inductors Overview

The ELJ-QE27NGFA is a surface-mount RF inductor from the Panasonic ELJQE series, designed for high-frequency applications. It features a non-magnetic ceramic core and a non-winding multilayer structure within a 0603 (1608 metric) package measuring 1.6 mm x 0.8 mm x 0.8 mm. The component provides an inductance of 27 nH with a tolerance of 5%. Key electrical parameters include a minimum Q factor of 15, a self-resonant frequency of 3.4 GHz, a maximum DC resistance of 660 mOhms, and a maximum DC current rating of 260 mA. It operates reliably between -20°C and +85°C.

Fixed Inductors Feature Summary

• Utilizes unique ceramic core and laser-cut technology to achieve high Q factors suitable for RF circuits.
• Features a non-magnetic, non-winding multilayer construction that prevents saturation effects common in wirewound designs.
• Capable of withstanding reflow or flow soldering processes without compromising structural integrity.

Fixed Inductors Applications

• RF signal processing circuits
• High-frequency communication systems
• Impedance matching networks

Fixed Inductors Procurement Notes

Verify availability status carefully as this component may be discontinued or subject to limited supply. Confirm RoHS compliance details through official manufacturer documentation before integration. Ensure ordering suffixes match exact specifications, as variations exist within the ELJQE family. Cross-reference datasheets for specific lot codes and manufacturing dates to guarantee authenticity and performance consistency.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-Q solution is required for RF filtering or matching. The 0603 footprint offers space efficiency compared to larger packages. Consider the 260 mA current limit and 660 mOhm resistance for power handling requirements. Compare against similar ELJQE variants if different inductance values or tighter tolerances are needed for the target circuit design.

Fixed Inductors Part Context

This part belongs to the ELJQE series of fixed chip inductors manufactured by Panasonic Industry. The series is characterized by its use of proprietary ceramic materials and laser-cut techniques to enhance high-frequency performance. These components are specifically engineered for surface mount technology (SMT) applications where size constraints and signal integrity are critical factors in electronic design.

Fixed Inductors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The ELJRE27NJFA is listed as a related product but has different electrical characteristics such as lower Q and DCR limits. Verify compatibility with any potential alternative components against the specific RF requirements of the application.
