CTS3F-4R7J

Fixed Inductors Overview

The CTS3F-4R7J is a fixed axial leaded molded shielded inductor from Central Technologies. It features an inductance of 4.7 µH with a ±5% tolerance. The component has a DC resistance of 0.55 Ω and a self-resonant frequency of 70 MHz. It supports a current rating of 380 mA and achieves a Q factor of 44 at the test frequency. The physical dimensions are 10.4 × 4.06 × 29.2 mm, designed for through-hole mounting.

Fixed Inductors Feature Summary

• Molded shielded construction to minimize electromagnetic interference
• Axial leaded package for through-hole PCB integration
• High self-resonant frequency for stable performance

Fixed Inductors Applications

• General purpose filtering circuits
• Power supply input/output stages
• Signal conditioning networks

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' confirms the ±5% tolerance requirement for your design. Ensure the 380 mA current rating meets the operational load. Confirm the axial lead length matches the board layout constraints. Check RoHS compliance status if restricted substances are prohibited in your manufacturing process.

Fixed Inductors Selection Notes

Select this component when a compact, shielded axial inductor is required for low-current applications. The 4.7 µH value suits intermediate frequency filtering. Consider the 0.55 Ω DCR impact on voltage drop. Compare against unshielded alternatives if EMI sensitivity is low. Verify thermal limits for high-temperature environments.

Fixed Inductors Part Context

This part belongs to the CTS3F series of fixed inductors. The series offers various inductance values and tolerance codes. The 'F' suffix typically denotes the molded shielded variant. Other parts in the family share similar physical dimensions but differ in electrical specifications.

Fixed Inductors Replacement Considerations

Direct substitutes must match the 4.7 µH inductance, ±5% tolerance, and 380 mA current rating. Axial leaded packages with similar dimensions ensure mechanical compatibility. Verify that replacement components offer equivalent shielding and self-resonant frequency characteristics.
