Procurement Notes
Verify the specific suffix against official documentation, as variants such as NBH-20-102-D indicate different mounting styles like DIN rail. Confirm that the terminal block interface matches your assembly requirements rather than screw or PCB options. Ensure the 20A current rating aligns with the system load. Check for updated certification marks on the latest production batches.
Selection Notes
Select this model when a two-stage filter topology is required for strict EMI compliance in chassis-mounted applications. The terminal block interface suits high-current wiring scenarios. Verify that the 250VAC/VDC ratings meet the circuit voltage specifications. Consider the physical dimensions and mounting hole patterns for panel integration. Compare leakage current specifications if sensitive to ground currents.
Part Context
This component belongs to the NBH series of power line filters from Cosel. The series offers various current ratings and mounting configurations. The NBH-20-102 specifically denotes the 20A chassis-mount variant with terminal blocks. Other series members may feature DIN rail mounting or different current capacities.
