ESP-03-101

Power Line Filter Modules Overview

The ESP-03-101 is a single-phase EMI/EMC power line filter manufactured by Cosel USA, Inc. It features a chassis mount configuration with screwless termination for secure electrical connections. The component is rated for 250 VAC and 250 VDC operation with a continuous current rating of 3 A. Key electrical specifications include a capacitance value of 100 pF and a leakage current of 12.5 uA. The unit belongs to the ES series and holds UL, CSA, DIN, and ENEC compliance certifications.

Power Line Filter Modules Feature Summary

• Single-stage electromagnetic interference suppression for single-phase circuits
• Screwless terminal design for rapid and reliable wiring installation
• Chassis mounting style for stable integration into equipment enclosures

Power Line Filter Modules Applications

• Industrial control systems requiring EMI noise reduction
• Medical equipment power input stages
• Commercial machinery power conditioning

Power Line Filter Modules Procurement Notes

Verify the specific suffix designation when ordering, as the ESP-03-101 typically denotes a chassis mount variant, whereas the ESP-03-101-D indicates a DIN rail mount version. Confirm that the required voltage and current ratings align with the system's operational parameters before procurement. Ensure compatibility with the intended mounting infrastructure and terminal connection methods specified in the official datasheet.

Power Line Filter Modules Selection Notes

Select this component for applications requiring single-phase filtering with a 3 A current capacity. The chassis mount form factor is suitable for direct panel installation where space allows. Compare the 100 pF capacitance value against system leakage current limits to ensure regulatory compliance. Verify that the screwless termination method matches the available wiring tools and conductor types for the target assembly process.

Power Line Filter Modules Part Context

This part belongs to the Cosel ES series of power line filters, designed for general-purpose EMI suppression. The series offers various current ratings and capacitance values to suit different power requirements. The ESP-03-101 specifically addresses low-current single-phase applications, providing a compact solution for noise mitigation in sensitive electronic environments.

Power Line Filter Modules Replacement Considerations

The ESP-03-101-D serves as a functional substitute if DIN rail mounting is preferred over chassis mounting, provided the electrical ratings remain identical. Other models within the ESP-03 series may be considered if different current or capacitance values are required.
