ELJ-RF15NGFB

Fixed Inductors Overview

The ELJ-RF15NGFB is a ceramic chip inductor from Panasonic, designed for high-frequency applications. It features a non-winding structure with an inductance of 0.015 µH (15 nH) and a tolerance of ±2%. Measured at 100 MHz, it offers a minimum Q factor of 8.0. The component has a maximum DC resistance of 0.6 Ω and supports a maximum DC current of 240 mA. Its self-resonant frequency is typically above 3 GHz. The physical dimensions are 1.0 mm x 0.5 mm, corresponding to the 0402 metric package.

Fixed Inductors Feature Summary

• Utilizes a non-winding ceramic structure for stable high-frequency performance
• Optimized for signal circuits requiring precise low-inductance values
• Compact rectangular form factor suitable for dense surface-mount layouts

Fixed Inductors Applications

• High-frequency circuit filtering
• RF signal path impedance matching
• Noise suppression in compact electronic devices

Fixed Inductors Procurement Notes

Verify the exact suffix and marking code against the manufacturer's latest datasheet to ensure compatibility with specific reflow soldering profiles. Confirm that the 240 mA current rating aligns with the thermal management requirements of the target application board. Check for any end-of-life notifications or obsolescence warnings prior to finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when a low inductance value near 15 nH is required for RF applications. Ensure the operating frequency remains below the self-resonant frequency to maintain inductive behavior. Verify that the PCB footprint matches the 1.0 mm by 0.5 mm dimensions. Consider the 0.6 ohm DC resistance impact on series loss if used in power-sensitive paths.

Fixed Inductors Part Context

This part belongs to Panasonic's ELJ-RF series of high-frequency chip inductors. These components are characterized by their ceramic construction and lack of magnetic cores, which minimizes saturation effects. The series is engineered for stability in microwave and RF environments where standard wire-wound inductors may exhibit parasitic issues.

Fixed Inductors Replacement Considerations

No direct substitute part numbers are publicly confirmed in the provided documentation. Cross-referencing tools suggest similar 0402 package inductors but do not guarantee electrical equivalence. Evaluate alternative vendors only after verifying identical inductance, Q factor, and current ratings.
