CT0402CSF-10NJ

Overview

The CT0402CSF-10NJ is a fixed surface-mount inductor manufactured by Central Technologies. It features a nominal inductance of 10 nH (0.01 µH) with a tolerance of ±5%. The component utilizes a ceramic core and wire-wound construction within a standard 0402 package footprint. Key electrical specifications include a maximum DC resistance of 0.41 Ω, a minimum quality factor of 8 at the nominal inductance, and a maximum rated current of 0.32 A. It operates within a temperature range of -40 °C to 100 °C.

Feature Summary

• Wire-wound construction on a ceramic core for stable RF performance
• Compact 0402 surface-mount design for space-constrained applications
• General-purpose inductor suitable for high-frequency circuits

Applications

• RF filter circuits
• High-frequency signal processing
• General-purpose SMD inductive components

Procurement Notes

Verify the specific manufacturer datasheet for the CT0402CSF-10NJ to confirm current production status and lead times. Ensure that the selected component meets all required environmental standards, including RoHS compliance and operating temperature ranges defined by the original equipment manufacturer documentation before finalizing procurement decisions.

Selection Notes

Select this component when a low-inductance value near 10 nH is required for RF or high-speed digital applications. Consider the 0.41 Ω DC resistance and 0.32 A current rating against circuit load requirements. The ceramic core construction offers advantages over iron powder cores for maintaining Q-factor at higher frequencies compared to general-purpose alternatives.

Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors from Central Technologies. The series includes various values such as 68 nH and 11 nH, sharing similar physical dimensions and construction methods. These components are designed for surface-mount technology (SMT) assembly processes, providing reliable performance in consumer electronics and communication devices requiring small form factors.

Replacement Considerations

Direct substitutes may include other 0402 ceramic-core wire-wound inductors with 10 nH ±5% tolerance. Verify compatibility regarding DC resistance, current rating, and physical footprint dimensions. Cross-reference with distributor databases for equivalent parts from other manufacturers offering identical electrical characteristics and package styles.
