4702-005TLF

Overview

The 4702-005TLF is a feedthrough capacitor from the Tusonix 4702 series, designed for EMI/RFI suppression. 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.

Feature Summary

• Three-terminal feedthrough architecture for effective EMI/RFI filtering
• High current handling capability suitable for power line applications
• Wide operating temperature range for harsh environments
• Surface mount compatible square pill form factor

Applications

• Power supply input filtering
• Signal line noise suppression
• Electronic equipment chassis grounding
• Military and aerospace systems

Procurement Notes

Verify the specific suffix 'TLF' against manufacturer documentation to confirm terminal configuration and plating specifications. Ensure compatibility with surface mount assembly processes given the square pill package type. Confirm RoHS compliance status if required by project standards. Cross-reference part numbers such as 4702-005MLF for potential equivalent options if availability is constrained.

Selection Notes

Select this component when high capacitance values are required alongside significant current carrying capacity. The 4000 pF rating makes it suitable for lower frequency filtering compared to smaller value variants in the same series. Consider the 100 VDC rating relative to the system voltage. The wide temperature range supports operation in demanding thermal conditions without derating concerns.

Part Context

This component belongs to the Tusonix 4702 series of three-terminal network filter capacitors. These devices are engineered for surface mount applications requiring compact footprints. The series offers various capacitance values while maintaining consistent physical dimensions and electrical characteristics across the family.

Replacement Considerations

The 4702-005MLF is listed as an alternative part number with identical electrical specifications including 4000 pF capacitance and 100 V rating. Verify mechanical mounting requirements before substitution.
