EMI470T-RC

Overview

The Bourns EMI470T-RC is a third-order T-type LC low-pass EMI filter designed for through-hole mounting. It features a radial package with three leads and a pitch of 2.54mm. The component has a maximum operating voltage of 50V and a current rating of 5A. Key electrical parameters include a capacitance of 47pF and a resistance of 0.05 Ohms. Physical dimensions are 9.00mm x 3.20mm in size with a height of 8.00mm.

Feature Summary

• Provides third-order low-pass filtering to attenuate electromagnetic interference
• Utilizes a T-network topology combining inductance and capacitance
• Supports high current handling up to 5A for power applications

Applications

• Power supply input stages
• Battery charger circuits
• Portable electronic devices

Procurement Notes

Verify the specific suffix RC confirms RoHS compliance and lead-free status as per manufacturer documentation. Ensure the radial lead configuration matches the PCB footprint requirements. Confirm the 5A current rating and 50V voltage limits align with the target circuit design specifications before finalizing procurement.

Selection Notes

Select this component when a compact, high-current T-filter is required for EMI suppression in low-voltage DC systems. The 47pF capacitance and 0.05 Ohm resistance define the cutoff characteristics. Consider the radial package constraints and 2.54mm pitch for board layout compatibility.

Part Context

This part belongs to the Bourns EMI470T series of anti-interference filters. It is distinct from other series by its specific T-network architecture and through-hole radial construction. The series is designed for general-purpose EMI/RFI suppression in consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes within the same series or equivalent T-filter topologies from other manufacturers. Verify that any replacement maintains the 5A current rating, 50V voltage limit, and similar physical dimensions for mechanical fit.
