NBM-06-221

Overview

The NBM-06-221 is a single-phase EMC/EMI power line filter module manufactured by Cosel USA, Inc. It features a two-stage configuration designed for electromagnetic interference suppression in general-purpose applications. The component supports AC voltages up to 250 VAC and DC voltages up to 250 VDC with a rated current of 6 A. It utilizes push-down terminals for connection and is intended for chassis mounting. The unit has a leakage current of 25 uA and operates within a frequency range of 10 kHz to 10 MHz.

Feature Summary

• Two-stage filtering architecture for enhanced noise attenuation
• Low leakage current design suitable for sensitive equipment
• Push-down terminal interface for simplified wiring

Applications

• General-purpose electromagnetic interference suppression
• Single-phase power line conditioning
• Industrial control systems requiring EMI filtering

Procurement Notes

Verify the specific part number against official Cosel documentation to confirm voltage ratings, current capacity, and terminal type. Ensure compatibility with chassis mounting requirements and verify that the push-down terminal style matches existing panel designs. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration.

Selection Notes

Select this model when a single-phase solution with low leakage current is required for chassis-mounted installations. The push-down terminal option offers faster assembly compared to screw types. Consider the 6 A current rating and 250 VAC/DC limits to ensure adequate headroom for the target circuit load and operating environment.

Part Context

This component belongs to the NBM series of power line filters from Cosel USA, Inc. The series provides various current ratings and capacitance values to suit different power line filtering needs. The NBM-06-221 specifically denotes a 6 A rated unit with 220 pF capacitance, distinguishing it from higher current variants like the NBM-30-221 or different capacitance models.

Replacement Considerations

Direct substitutes may include other Cosel NBM series units with matching current and voltage ratings, such as NBM-06-471 if higher capacitance is acceptable. Verify mechanical dimensions and terminal compatibility before replacing with components from other manufacturers.
