Overview
The NBM-10-221-D is a single-phase power line filter from the Cosel NB series, rated for 10 A current and 250 VAC/VDC. It features a low leakage current design with a maximum of 25 µA/50 µA and a capacitance of 220 pF. The unit utilizes push-down terminal connections and is designed for DIN rail mounting. This component serves as an EMC/EMI filter to suppress electromagnetic interference in AC and DC circuits.
Feature Summary
- Low leakage current capability suitable for sensitive applications
- Two-stage filtering architecture for effective noise suppression
- Push-down terminal connection system for simplified wiring
Applications
- Industrial control systems requiring EMI suppression
- Medical equipment power input stages
- Precision instrumentation power conditioning
Procurement Notes
Verify the specific suffix designation to confirm the mounting style, as variants exist for chassis and DIN rail installation. Ensure the voltage rating matches the operational circuit requirements. Confirm compliance certifications such as UL, CSA, or VDE are required for the target market. Check lead times as production cycles may vary by manufacturer batch.
Selection Notes
Select this model when a low leakage current specification is critical for safety or signal integrity. The 10 A rating suits moderate power loads. Compare against the NBM-10-221 if chassis mounting is preferred over DIN rail. Verify that the 220 pF capacitance does not interfere with specific circuit grounding schemes.
Part Context
This component belongs to the Cosel NB series of power line filters. The series offers various current ratings and mounting options. The NBM-10-221-D specifically denotes the 10 A variant with DIN rail compatibility. Other models in the family include higher current ratings like 20 A or 30 A with different leakage characteristics.
Replacement Considerations
The NBM-10-221 is a related variant within the same series but typically differs in mounting style, often supporting chassis mount instead of DIN rail. Verify physical dimensions and terminal orientation before substitution.
