4700-005T

Overview

The 4700-005T is a surface-mount LC (Pi) EMI filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It integrates a 0.1 µH inductor and a 1000 pF capacitor within a single pill-shaped package. The component is rated for a maximum voltage of 100V and operates reliably across a temperature range of -55°C to +125°C. Designed for high-frequency noise suppression, it provides third-order filtering characteristics suitable for compact electronic assemblies requiring efficient electromagnetic interference mitigation.

Feature Summary

• Integrates LC (Pi) topology combining inductive and capacitive elements for third-order filtering
• Surface-mount construction enables automated assembly and space-efficient PCB layouts
• Pill-shaped square package design facilitates secure mounting on printed circuit boards

Applications

• General purpose electromagnetic interference suppression
• High-frequency signal line filtering in compact electronics
• Power supply input/output noise reduction

Procurement Notes

Verify the exact suffix designation during procurement, as variations such as LF or M may indicate different material compositions or packaging types. Confirm that the specific part number matches the required surface-mount configuration and thermal ratings. Ensure compatibility with standard pick-and-place equipment due to the pill package form factor. Cross-reference manufacturer documentation to validate current production status and availability constraints.

Selection Notes

Select this component when a combined inductor-capacitor solution is required for high-density designs. The integrated nature reduces component count compared to discrete LC filters. Evaluate the 0.1 µH inductance and 1000 pF capacitance values against target cutoff frequencies. Consider the 100V rating and wide operating temperature range for robustness in demanding environments.

Part Context

This component belongs to the 4700 series of feedthrough and surface-mount filters from Tusonix. The series offers various capacitance and inductance combinations tailored for EMI/RFI suppression. The 4700-005T specifically addresses applications needing third-order filtering in a minimal footprint, distinguishing it from simple capacitive feedthroughs.
