4702-005MLF

Overview

The 4702-005MLF is a feedthrough capacitor from the Tusonix 4702 series, designed for EMI/RFI filtering. It features a capacitance of 4000 pF with a tolerance of -20%, +80%. Rated for 100 VDC and capable of handling 20 A current, it operates within a temperature range of -55°C to 125°C. The component utilizes a square pill package measuring 8.00 mm in length, 2.29 mm in width, and 2.42 mm in maximum height. It provides an insertion loss of 30 dB at 100 MHz and complies with RoHS3 standards.

Feature Summary

• Provides effective electromagnetic interference suppression through high-current feedthrough architecture
• Supports surface mount integration via a compact square pill footprint
• Maintains stable electrical performance across extended industrial temperature ranges

Applications

• Power supply input filtering for electronic equipment
• Signal line protection against radio frequency interference
• EMI suppression in aerospace and military communication systems

Procurement Notes

Verify that the suffix MLF confirms RoHS3 compliance and lead-free termination requirements. Confirm the specific packaging format (TR, CT, or Digi-Reel) matches assembly line capabilities. Ensure the -20%, +80% capacitance tolerance aligns with circuit design specifications. Validate that the 20 A current rating exceeds peak operational loads to prevent component failure.

Selection Notes

Select this component when a 4000 pF capacitance value is required for high-frequency noise attenuation. The 100 VDC rating suits low-voltage DC distribution networks. The square pill form factor facilitates automated pick-and-place mounting. Consider the 20 A current capacity for applications involving significant power line filtering needs without excessive thermal rise.

Part Context

This part belongs to the Tusonix 4702 series of three-terminal network filter capacitors. These components are engineered as surface-mount EMI/RFI filters. They integrate a capacitor between the center conductor and ground terminal to shunt high-frequency noise. The series offers various capacitance values while maintaining consistent mechanical dimensions for board layout standardization.

Replacement Considerations

The 4702-005M is a non-RoHS variant with identical electrical characteristics. Verify environmental compliance requirements before substitution. Other series like 4700 offer different current ratings and temperature limits.
