Procurement Notes
Verify the specific capacitance suffix (221) against project requirements to ensure correct filtering characteristics. Confirm that the chassis mount form factor fits the enclosure design. Check RoHS compliance status via the manufacturer datasheet before finalizing procurement decisions.
Selection Notes
Select this model when a 16A current rating and 250VAC/VDC voltage tolerance are required. The two-stage design offers superior attenuation compared to single-stage alternatives. Ensure the application environment accommodates chassis mounting constraints and utilizes compatible push-down terminals for reliable electrical contact.
Part Context
This component belongs to the Cosel NBM series of power line filters. The series provides various current ratings and capacitance options to suit different noise suppression needs. The NBM-16-221 specifically addresses high-current applications requiring robust EMI filtering capabilities within a compact chassis-mountable package.
Replacement Considerations
Direct substitutes may include other Cosel NBM-16 variants with different capacitance values, such as NBM-16-471 or NBM-16-101, if filtering requirements differ. Verify that any replacement maintains the 16A current rating and 250VAC/VDC voltage specification.
