CT0402CSF-51NG

Overview

The CT0402CSF-51NG is a fixed surface-mount inductor from Central Technologies, designed for general-purpose applications. It features a nominal inductance of 51 nH with a tight tolerance of ±2%. The component utilizes a ceramic core and wire-wound construction within a compact 0402 package. Key electrical specifications include a maximum rated current of 0.76 A, a minimum quality factor of 20 at the nominal inductance, and a self-resilient frequency of 2 GHz. It operates reliably across a temperature range of -40 °C to 125 °C.

Feature Summary

• Wire-wound construction on a ceramic core for stable RF performance
• Compact 0402 surface-mount footprint for high-density layouts
• High Q-factor capability suitable for resonant circuits

Applications

• RF filter networks
• Impedance matching circuits
• General purpose signal processing

Procurement Notes

Verify the specific ordering suffix when placing orders, as tolerance codes are critical for this series. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected variant matches the required inductance tolerance for the target application design.

Selection Notes

Select this component for designs requiring precise inductance values in small form factors. The ±2% tolerance offers higher precision than standard 5% variants. Consider the 2 GHz self-resonant frequency limit when designing for high-frequency signals. Evaluate thermal requirements against the 125 °C maximum operating temperature rating.

Part Context

This part belongs to the CT0402CSF series of open-type wire-wound chip inductors. The series provides various inductance values ranging from low nanohenry ranges up to higher values, all housed in the standardized 0402 SMD package. These components are engineered for use in consumer electronics and communication devices where space is limited.

Replacement Considerations

Compatible substitutes within the same series include other CT0402CSF variants with different inductance values but identical package dimensions. Cross-referencing with other manufacturers' 0402 ceramic-core wire-wound inductors requires verifying that the self-resonant frequency and DC resistance parameters meet or exceed the original specifications.
