Procurement Notes
Verify the exact part number against official Sumida documentation before procurement. Confirm that the suffix B-B502 corresponds to the specific 10 mH inductance and 260 mA current rating. Ensure compatibility with existing PCB footprints and thermal requirements. Cross-reference datasheet specifications for DC resistance and operating temperature limits to validate suitability for the target application environment.
Selection Notes
Select this component when a 10 mH common mode choke with through-hole termination is required. Verify that the 260 mA current rating meets the circuit's operational demands. Check that the 350 Ohm DC resistance does not introduce excessive voltage drop. Ensure the vertical pin spacing matches the PCB layout constraints and that the operating temperature range covers the intended environmental conditions.
Part Context
This component belongs to the UU9LFBNP series of common mode chokes from Sumida. The series offers various inductance values and current ratings for different filtering needs. The UU9LFBNP-B-B502 specifically provides high inductance for effective low-frequency noise attenuation while maintaining a compact form factor suitable for space-constrained designs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Sumida technical support or authorized distributors for verified alternatives with matching electrical and mechanical specifications.
