EMI271T-RC

Overview

The EMI271T-RC is a third-order LC T-type electromagnetic interference filter manufactured by Bourns Inc. It features a radial through-hole package with three leads and measures 9x8x3.2mm. The component has a rated voltage of 50V, a current rating of 5A, an inductance resistance of 0.05 Ohms, and a capacitance of 270pF. It is RoHS compliant and lead-free.

Feature Summary

• Provides third-order low-pass filtering for effective noise suppression
• Utilizes a compact T-network LC topology
• Designed for through-hole mounting applications

Applications

• General electronic circuit noise suppression
• Power supply input filtering
• Signal line interference reduction

Procurement Notes

Verify the specific suffix RC confirms lead-free and RoHS compliance status as documented. Confirm the radial three-lead package dimensions match the 9x8x3.2mm specification required for your PCB layout. Ensure the 5A current rating and 50V voltage rating meet your circuit requirements before procurement.

Selection Notes

Select this component when a third-order attenuation characteristic is required for EMI suppression. The T-type configuration offers specific impedance matching properties compared to Pi filters. Consider the radial through-hole form factor if surface mount options are not suitable for the assembly process or mechanical stress requirements.

Part Context

This part belongs to Bourns' EMI/RFI filter product line, specifically within the LC network category. It is designed to complement other passive components in power and signal conditioning circuits. The manufacturer provides datasheets detailing electrical characteristics and mechanical drawings for integration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by comparing electrical parameters such as inductance, capacitance, and current ratings against alternative components.
