IS-0442H2

Power Line Filter Modules Overview

The IS-0442H2 is a single-phase EMC/EMI line filter manufactured by DIT. It is rated for 4 A current and operates at voltages up to 250 VAC/VDC within a frequency range of 50 to 60 Hz. The component utilizes a single-stage filtering architecture and features panel mount installation. It incorporates an IEC 320-C14 connector interface with quick connect terminals, housed in a metal case to provide effective electromagnetic interference suppression.

Power Line Filter Modules Feature Summary

• Integrates a fuse holder and double pole power ON/OFF switch
• Provides good shield effect using a metal case construction
• Meets over voltage category II requirements per IEC 60664

Power Line Filter Modules Applications

• General-purpose electromagnetic interference suppression
• Single-phase power line filtering
• Equipment requiring IEC 320-C14 inlet compatibility

Power Line Filter Modules Procurement Notes

Verify the specific suffix variant against official DIT documentation to confirm exact terminal type and enclosure specifications. Ensure the selected unit meets the required over-voltage category II standard for your application environment. Cross-reference the IEC 320-C14 mating connector compatibility before integration into the final assembly design.

Power Line Filter Modules Selection Notes

Select this component when single-stage EMI attenuation is sufficient for the noise profile. The integrated switch and fuse holder simplify system design by reducing external component count. Verify that the 4 A rating aligns with the maximum load current and that the panel mount form factor fits the available chassis space.

Power Line Filter Modules Part Context

This part belongs to the DIT series of single-phase power line filters. These components are designed to suppress conducted emissions from switching power supplies and other electronic loads. The metal housing distinguishes it from plastic-housed alternatives, offering enhanced shielding capabilities for sensitive applications.

Power Line Filter Modules Replacement Considerations

Check for direct substitutes with identical IEC 320-C14 interfaces and 4 A ratings. Ensure replacement units maintain the same panel mount dimensions and include equivalent protective features such as integrated fusing and switching mechanisms.
