IQ-0442H2

Power Line Filter Modules Overview

The IQ-0442H2 is a single-phase EMC/EMI line filter manufactured by DIT. It features a rated AC voltage of 250V and a current capacity of 4A, operating at frequencies between 50Hz and 60Hz. The unit incorporates a metal case for effective shielding and includes an integrated fuse holder and a double-pole power ON/OFF switch. Designed to meet the overvoltage category II requirements of IEC 60664, it utilizes a single-stage filtering architecture with Quick Connect terminals compatible with IEC 320-C14 inputs.

Power Line Filter Modules Feature Summary

• Integrated double-pole power ON/OFF switch and fuse holder
• Metal case construction providing good electromagnetic shielding effect
• Single-stage EMI/EMC filtering design for general-purpose suppression

Power Line Filter Modules Applications

• General-purpose electronic equipment requiring EMI suppression
• Single-phase AC power line filtering
• Equipment meeting IEC 60664 overvoltage category II standards

Power Line Filter Modules Procurement Notes

Verify that the specific order matches the IQ-0442H2 designation rather than similar variants like IP-0442H2 or IQ-0242H2. Confirm the presence of the integrated switch and fuse holder if required. Ensure compatibility with IEC 320-C14 connectors and Quick Connect terminal types. Check for compliance with IEC 60664 overvoltage category II specifications before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when a compact, single-phase filter with built-in switching and protection is needed. The 4A rating suits moderate power applications. The metal enclosure offers superior shielding compared to plastic alternatives. Verify that the operating frequency range of 50-60Hz aligns with the target power system.

Power Line Filter Modules Part Context

This part belongs to the DIT IQ series of power line filters. These modules are designed for direct connection to AC mains via standard IEC inlet connectors. The series emphasizes safety and interference reduction through integrated mechanical switches and fusing within a shielded metal housing.

Power Line Filter Modules Replacement Considerations

Cross-reference with IP-0442H2 only if functional equivalence is confirmed via official documentation. Do not assume interchangeability with IQ-0242H2 due to potential specification differences.
