CT0402CSF-13NJ

Overview

The CT0402CSF-13NJ is a fixed inductor from Central Technologies, designed for surface-mount applications. It features a ceramic core and wire-wound construction within a standard 0402 (1005 metric) rectangular package. The component has a nominal inductance of 13 nH with a tolerance code 'J' indicating ±5%. It operates at a maximum rated current of 0.31 A and exhibits a DC resistance of 0.46 Ω. The self-resonant frequency is specified at 2200 MHz, supporting RF applications. The device functions reliably within an ambient temperature range of -40 °C to 125 °C.

Feature Summary

• Wire-wound chip inductor architecture utilizing a ceramic core for stable performance
• Surface-mount design compatible with automated assembly processes
• High self-resonant frequency suitable for radio frequency signal handling

Applications

• RF Inductor circuits
• General Purpose Inductor applications
• Communication Device modules

Procurement Notes

Verify the specific suffix 'NJ' corresponds to the required ±5% tolerance when ordering, as other codes like 'G' or 'K' denote different tolerances. Confirm RoHS compliance status, as datasheets indicate this series may not be fully compliant depending on the specific variant. Ensure the 0402 footprint matches the PCB layout constraints and that the 0.31 A current rating meets the circuit's peak load requirements without saturation.

Selection Notes

Select this component for designs requiring precise low-nanohenry inductance values in compact spaces. The 13 nH value is ideal for high-frequency filtering or impedance matching networks where space is limited. Consider the 0.46 Ω DC resistance impact on power loss if the operating current approaches the 0.31 A limit. Compare against multilayer alternatives if higher Q-factors are needed, though wire-wound types offer specific magnetic properties.

Part Context

This part belongs to the CT0402CSF series of wire-wound chip inductors manufactured by Central Technologies. The series offers a wide range of inductance values from 1.0 nH to 68 nH in the 0402 package. It is positioned as a general-purpose solution for consumer electronics and communication devices, balancing size, performance, and cost for mass-produced hardware.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 13 nH inductance, ±5% tolerance, 0402 package dimensions, and similar current/DCR specifications from other manufacturers.
