3-121-370

Overview

The Schurter 3-121-370 is a screw-mount power line filter designed for AC mains protection. It features a rated voltage of 250VAC and a current rating of 1A. The component utilizes quick-connect terminals for circuit integration and employs panel mounting for secure installation. This unit provides electromagnetic interference suppression to ensure signal integrity in connected electrical systems.

Feature Summary

• Provides electromagnetic interference suppression for AC power lines
• Features quick-connect terminals for simplified circuit integration
• Designed for secure panel mounting applications

Applications

• Protection of electronic equipment from mains-borne noise
• Integration into devices requiring AC power line filtering
• Installation in panels where space-efficient mounting is required

Procurement Notes

Verify the specific datasheet version for the 3-121-370 to confirm terminal pitch dimensions and mounting hole specifications before procurement. Ensure that the selected housing or panel cutout matches the physical requirements of this screw-mount filter type. Cross-reference the manufacturer's official documentation to validate compliance with relevant regional safety standards applicable to your deployment environment.

Selection Notes

Select this component when a compact, screw-mounted solution is required for low-current AC applications. The 1A rating suits light-duty electronics, while the 250VAC specification aligns with standard global mains voltages. Consider the quick-connect interface if rapid assembly or maintenance access is a priority over soldered connections in the final product design.

Part Context

This part belongs to Schurter’s range of passive EMI suppression components. It serves as a critical interface between the AC power source and sensitive downstream electronics. The design prioritizes reliable noise attenuation within a standardized form factor suitable for industrial and commercial enclosures.

Replacement Considerations
