CTTF0402F-15NG

Overview

The CTTF0402F-15NG is a fixed thin film inductor manufactured by Central Technologies, designed for surface-mount applications. It features an unshielded construction within a standard 0402 (1005 Metric) package footprint. The component provides an inductance value of 15 nH with a tolerance specification typically associated with the series. It supports a maximum DC current rating of 130 mA and exhibits a maximum DC resistance (DCR) of 1.8 Ohms. Key electrical characteristics include a quality factor (Q) of 13 at 500 MHz and a self-resonant frequency of 3.3 GHz. The device operates reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Thin film technology ensures high precision and stability for RF signal paths
• Unshielded design minimizes parasitic coupling effects in dense layouts
• Compact 0402 surface-mount form factor facilitates automated assembly

Applications

• RF matching networks in wireless communication modules
• Impedance matching circuits for high-frequency signal processing
• Filter components in RF front-end assemblies

Procurement Notes

Verify the specific tolerance suffix if critical precision is required, as standard designations may vary. Confirm that the 130 mA current rating aligns with peak operational loads to prevent thermal degradation. Ensure PCB pad dimensions match the 0402 footprint guidelines provided in the official datasheet to guarantee reliable solder joint integrity during reflow processes.

Selection Notes

Select this component when a low-inductance, high-Q solution is needed for frequencies near 500 MHz. The 1.8 Ohm DCR limit suits low-current signal paths rather than power handling. Consider the unshielded nature for applications where magnetic interference from adjacent components must be minimized or managed through layout spacing.

Part Context

This part belongs to the CTTF0402F series of thin film chip inductors from Central Technologies. The series offers various inductance values optimized for RF applications. The '15NG' designation specifically identifies the 15 nH variant within this unshielded product line, distinguishing it from shielded or higher-current alternatives in the manufacturer's catalog.

Replacement Considerations

Direct substitutes require identical 15 nH inductance, 0402 package, and comparable Q factors at 500 MHz. Verify that alternative manufacturers offer similar 1.8 Ohm DCR limits and 130 mA ratings. Cross-reference self-resonant frequency specifications to ensure no impedance anomalies occur at 3.3 GHz.
