Power Line Filter Modules Procurement Notes

Verify the specific datasheet version for the ESM-03-101 model to confirm exact mechanical dimensions and pinout configurations. Ensure that the operating environment temperature remains within the specified -40°C to 85°C range. Confirm compliance requirements such as UL or CSA match the target market regulations before finalizing procurement decisions.

Power Line Filter Modules Selection Notes

Select this component when a compact, single-phase filter is required for chassis-mounted applications. The screwless termination simplifies assembly compared to traditional screw terminals. Consider the 3 A current rating and 250 VAC/VDC limits to ensure adequate headroom for the specific circuit design without exceeding electrical ratings.

Power Line Filter Modules Part Context

This part belongs to the ESM series of power line filters from Cosel USA, Inc. The series offers various current ratings and mounting options. The ESM-03-101 specifically denotes the 3 A variant with chassis mounting capabilities. It is distinct from the DIN rail mounted variants in the same family.

Power Line Filter Modules Replacement Considerations

Direct substitutes may include other single-phase EMI filters with similar 3 A ratings and chassis mounting styles. Verify that replacement parts maintain equivalent leakage current and capacitance values to ensure compatibility with sensitive downstream components.
