4700-003T

Overview

The 4700-003T is a surface-mount EMI/RFI filter capacitor manufactured by Tusonix, a subsidiary of CTS Electronic Components. It features an LC (Pi) network topology with a nominal capacitance of 2000 pF and an inductance of 0.1 uH. The component is rated for 100 VDC and supports a continuous current of 10 A. Designed for high-frequency noise suppression, it operates within a temperature range of -55°C to +125°C. The device utilizes a three-terminal SMD package configuration.

Feature Summary

• Integrates LC (Pi) network filtering for effective EMI/RFI suppression
• Utilizes a compact surface-mount three-terminal design
• Supports high continuous current handling capabilities

Applications

• High-speed data handling circuits
• FPGA power supply filtering
• Control system signal conditioning

Procurement Notes

Verify the specific suffix 'T' against official datasheets to confirm surface-mount packaging and exact electrical tolerances. Ensure compatibility with automated pick-and-place equipment due to the SMD form factor. Cross-reference thermal ratings with application requirements to maintain performance within the specified operating temperature range.

Selection Notes

Select this component when space-constrained PCB layouts require integrated LC filtering rather than discrete components. The 2000 pF value targets mid-to-high frequency noise attenuation. Confirm that the 10 A current rating aligns with the circuit's maximum load demands without exceeding thermal limits.

Part Context

This part belongs to the 4700 series of feedthrough capacitors from Tusonix/CTS. While similar to through-hole variants like the 4400 series, the 4700-003T is specifically engineered for surface-mount technology. It shares the manufacturer's focus on robust EMI suppression but differs in physical implementation and mounting style compared to axial leaded counterparts.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters before considering alternative manufacturers.
