3-143-618

Overview

The Schurter 3-143-618 is a single-phase EMC/EMI power line filter module designed for AC circuits. It features a rated current of 4 A and operates at 250 VAC with 50/60 Hz frequency. The unit utilizes a quick connect terminal interface with dimensions of 6.3 x 0.8 mm. Certified for medical applications under the M80 version, it provides high-performance filtering in a compact form factor measuring 51 mm in length. Operating temperatures range from -40°C to +100°C.

Feature Summary

• Single-stage electromagnetic interference suppression for single-phase AC lines
• Medical device certification compliant with M80 standards
• Quick connect terminal configuration for simplified PCB integration

Applications

• Single-phase AC power input stages in medical equipment
• EMC compliance filtering for electronic devices requiring M80 certification
• Power line noise reduction in industrial control systems

Procurement Notes

Verify that the specific order corresponds to the M80 medical version, as this designation indicates compliance with specific medical safety standards distinct from general industrial variants. Confirm the quick connect terminal pitch matches the target PCB footprint before integration. Ensure the application environment remains within the specified -40°C to +100°C operating temperature range to maintain performance integrity.

Selection Notes

Select this component when medical certification (M80) is mandatory for the end product. The 4 A rating suits moderate power applications, while the single-stage design offers cost-effective EMI reduction. Verify that the 250 VAC rating aligns with the local mains voltage requirements. Consider the physical length of 51 mm during enclosure layout planning.
