CT0603CSF-12NJ

Fixed Inductors Overview

The CT0603CSF-12NJ is a general-purpose wire-wound chip inductor from Central Technologies, designed for surface-mount applications. It features a ceramic core and operates within a temperature range of -40 °C to 125 °C. The component has a nominal inductance of 0.012 µH with a tolerance of ±5%. Key electrical specifications include a maximum DC resistance of 86 mΩ, a minimum quality factor of 24 at 200 MHz, and a maximum rated current of 0.7 A.

Fixed Inductors Feature Summary

• Utilizes a ceramic core construction for stable inductance characteristics
• Designed as a high-current inductor suitable for demanding circuit loads
• Compliant with RoHS standards and lead-free manufacturing processes

Fixed Inductors Applications

• High current inductor circuits
• General purpose signal filtering
• RF circuit impedance matching

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' confirms the ±5% tolerance rating when ordering. Ensure the package size matches the 0603 footprint requirements of the target PCB layout. Confirm that the operating temperature range of -40 °C to 125 °C aligns with the environmental conditions of the intended application. Cross-reference the DC resistance value of 86 mΩ against power loss constraints.

Fixed Inductors Selection Notes

Select this component when a low-inductance, high-current solution is required in a compact 0603 package. The ceramic core provides stability compared to iron powder alternatives. Consider the 0.7 A current rating to ensure it exceeds the peak current demands of the circuit. The 200 MHz test frequency indicates suitability for higher frequency applications where lower parasitic effects are critical.

Fixed Inductors Part Context

This part belongs to the CT0603CSF series of wire-wound chip inductors manufactured by Central Technologies. The series offers various inductance values ranging from 1.6 nH to 390 nH. The 'CSF' designation typically denotes a ceramic core construction optimized for high-current performance. This specific model represents one of the lower inductance options available in the lineup.

Fixed Inductors Replacement Considerations

Direct substitutes include other CT0603CSF variants with different tolerances such as CT0603CSF-12NG or CT0603CSF-12NK, provided the tolerance change is acceptable. Cross-manufacturer equivalents like Wurth Elektronik WE-KI HC series may offer similar form-factor and performance characteristics.
