4700-059MLF

Overview

The 4700-059MLF is a surface-mount EMI feedthrough capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features a capacitance of 100 pF and a DC voltage rating of 100 VDC. The component utilizes an LC (Pi) filter topology to provide third-order low-pass filtering characteristics. Designed for high-frequency noise suppression, it operates within a temperature range of -55°C to +125°C. The device is housed in a compact square pill package with three terminals, suitable for automated surface-mount assembly processes.

Feature Summary

• Integrates LC (Pi) network topology for enhanced third-order low-pass filtering performance
• Provides effective electromagnetic interference (EMI) and radio frequency interference (RFI) suppression
• Features a compact square pill package designed for efficient surface-mount technology integration

Applications

• General purpose electronic circuit noise filtering
• High-frequency signal line protection against EMI/RFI
• Surface-mount assembly in compact electronic devices

Procurement Notes

Verify the specific suffix 'MLF' to confirm lead-free compliance status as indicated by distributor listings. Ensure the selected variant matches the required 100 pF capacitance and 100 VDC rating for your circuit design. Confirm that the surface-mount square pill package dimensions align with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a third-order low-pass filter response is required in a surface-mount configuration. The 100 pF value is suitable for high-frequency noise attenuation where minimal capacitance loading is necessary. Consider the 100 VDC rating and wide operating temperature range for robustness in demanding environments compared to lower-rated alternatives.

Part Context

This component belongs to the 4700 series of feedthrough capacitors from Tusonix/CTS. The series offers various capacitance values and voltage ratings in surface-mount packages. The 4700-059MLF specifically addresses applications requiring precise 100 pF filtering in a compact form factor, distinguishing it from axial or through-hole variants within the broader product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative surface-mount Pi filters based on identical capacitance, voltage rating, and package dimensions if direct substitution is required.
