CT0402CSF-43NJ

Fixed Inductors Overview

The CT0402CSF-43NJ is a wire-wound chip inductor from Central Technologies, designed for surface-mount applications. It features a nominal inductance of 43 nH with a tolerance of ±5%. The component has a DC resistance of 0.5 Ω and a maximum rated current of 300 mA. It operates within a temperature range of -40 °C to 125 °C. The self-resonant frequency is specified at 2 MHz, and the minimum quality factor at the nominal inductance is 26. The package dimensions are 1.0 × 0.68 × 0.55 mm.

Fixed Inductors Feature Summary

• Wire-wound construction on an open core structure
• Surface-mount compatible rectangular package
• RoHS compliant lead-free termination

Fixed Inductors Applications

• RF inductor circuits
• General purpose filtering
• Signal conditioning

Fixed Inductors Procurement Notes

Verify RoHS compliance status and lead-free designation against the specific manufacturing batch documentation. Confirm that the ±5% tolerance code 'J' matches the design requirements. Ensure the operating temperature range up to 125 °C aligns with the thermal profile of the target application environment.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 43 nH is required in a compact 0402 footprint. Consider the 300 mA current rating and 0.5 Ω DC resistance for power handling needs. Verify that the 2 MHz self-resonant frequency is sufficient for the intended signal frequencies to avoid parasitic resonance issues.

Fixed Inductors Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors manufactured by Central Technologies. The series offers various inductance values in the 0402 package size. The 'F' suffix typically denotes RoHS compliance, while 'J' indicates the ±5% tolerance class.

Fixed Inductors Replacement Considerations

Cross-reference with other 43 nH ±5% inductors in the 0402 package. Ensure equivalent DC resistance and current ratings. Verify mechanical compatibility and soldering process requirements.
