CT0603CTF-22NG

Fixed Inductors Overview

The CT0603CTF-22NG 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 22 nH with a tolerance of ±2%. Key electrical specifications include a DC resistance of 0.335 Ω, a maximum rated current of 600 mA, and a minimum quality factor of 28 at the nominal inductance. The package dimensions are 1.6 mm x 0.9 mm x 0.55 mm.

Fixed Inductors Feature Summary

• Wire-wound construction on a ceramic core for stable inductance
• High-current capability suitable for power filtering
• Precision ±2% tolerance for tight circuit requirements

Fixed Inductors Applications

• RF circuits requiring precise impedance matching
• DC-DC converter input/output filtering
• Signal line noise suppression

Fixed Inductors Procurement Notes

Verify RoHS compliance status as datasheets may vary by production batch; confirm lead-free soldering compatibility for assembly processes. Ensure ordering suffixes match required tolerance codes. Cross-reference manufacturer part numbers against distributor catalogs to avoid counterfeit components. Request material traceability documentation for critical supply chain audits.

Fixed Inductors Selection Notes

Select this component when a low-profile 0603 footprint is required alongside high current handling. Compare DCR and Q-factor against similar inductors to minimize power loss. Verify self-resonant frequency constraints relative to operating bandwidth. Consider thermal derating curves if ambient temperatures exceed standard limits.

Fixed Inductors Part Context

This part belongs to the CT0603CTF series of fixed wire-wound inductors. The series offers various inductance values from 1.6 nH to 390 nH. It is distinct from the CT0603CS series which may have different tolerance or lead-free specifications. The CTF designation typically indicates specific winding and termination characteristics optimized for SMD reflow processes.

Fixed Inductors Replacement Considerations

Direct substitutes include other 22 nH ±2% 0603 ceramic-core wire-wound inductors from manufacturers like Murata or TDK. Verify that replacement parts meet the same 600 mA current rating and 0.335 Ω max DCR. Check physical dimension compatibility for PCB layout reuse.
