Procurement Notes

Verify the specific suffix designation when ordering, as variants such as NBM-30-471-D exist with different mounting styles like DIN rail. Confirm that the required termination type matches the chassis mount specification of this part number. Ensure the application voltage does not exceed the 250 VAC or 250 VDC limits. Check for regional certification requirements such as VDE or cURus if applicable to the final assembly.

Selection Notes

Select this model when a 30 A current capacity is required alongside stringent leakage current constraints. The 470 pF capacitance offers a specific noise attenuation profile suitable for general EMI suppression. Compare against the NBM-30-471-D variant if DIN rail mounting is preferred over chassis installation. Ensure the operating temperature range of -40°C to 85°C aligns with the environmental conditions of the target enclosure.

Part Context

This component belongs to the Cosel NB series of power line filters. The series includes various current ratings and capacitance values to address different EMI suppression needs. The NBM-30-471 specifically targets high-current applications where low leakage is critical. Other models in the lineup may offer different mounting options or voltage ratings.

Replacement Considerations

The NBM-30-471-D is a related variant within the same series but typically features DIN rail mounting instead of chassis mounting. Verify mechanical fitment before substitution. No other direct cross-model replacements are confirmed in the provided documentation.
