EMI103T-RC

Overview

The EMI103T-RC is a single-function EMI power line filter manufactured by Bourns Inc. It features a T-type LC network configuration designed for through-hole mounting. The component supports a maximum current rating of 5A and operates with a voltage rating of 50V. It provides an attenuation of 25 dB within the frequency range of 15 MHz to 200 MHz. The physical package dimensions are 9 x 3.2 x 8 mm, and it is supplied in an ammo pack for automated insertion.

Feature Summary

• Utilizes a T-type LC network topology for effective electromagnetic interference suppression
• Designed for through-hole PCB mounting with compact physical dimensions
• Capable of handling high continuous current loads up to 5A

Applications

• Power supply input filtering
• Electronic equipment noise reduction
• Industrial control circuit protection

Procurement Notes

Verify the specific datasheet version when sourcing, as packaging details may vary between standard tape-and-reel and ammo pack configurations. Confirm that the 5A current rating aligns with the thermal management capabilities of the target PCB layout. Ensure the 50V DC rating meets the system's maximum operating voltage requirements without derating issues.

Selection Notes

Select this component when a low-profile, through-hole EMI filter is required for moderate current applications. The T-network design offers a balance between size and attenuation performance in the VHF/UHF range. Consider the 9mm length for spatial constraints on the board. Verify compatibility with automated assembly processes if using the taped packaging option.

Part Context

This part belongs to the Bourns EMI T series of network filters. These components are engineered to suppress conducted emissions in electronic circuits. The series typically includes various capacitance and inductance values to suit different frequency and current requirements. The EMI103T-RC specifically targets applications requiring robust filtering in a small form factor.

Replacement Considerations

Direct substitutes must match the 5A current rating, 50V voltage rating, and T-network topology. Verify that alternative components provide equivalent attenuation characteristics in the 15-200 MHz range. Ensure physical footprint compatibility for through-hole mounting before substitution.
