Overview
The KEMET ST-110BV is a through-hole common mode choke designed for DC line filtering. It utilizes proprietary manganese-zinc ferrite material and features a toroidal core construction. The component has a maximum DC current rating of 150 mA and a DC resistance of 7.5 Ohms. It withstands 500 VDC for one minute between lines and offers insulation resistance exceeding 10 MΩ at 250 VDC. Operating temperatures range from -20°C to +75°C.
Feature Summary
- Proprietary manganese-zinc ferrite material for effective noise suppression
- Through-hole toroidal design for robust mechanical mounting
- High dielectric strength withstanding 500 VDC test voltage
Applications
- DC power line filtering in electronic circuits
- Common mode noise reduction in low-current signal paths
- Electromagnetic interference suppression in consumer electronics
Procurement Notes
Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters such as DC resistance and current ratings. Ensure the through-hole package dimensions match the target PCB layout. Confirm compliance requirements including RoHS status and lead-free specifications before finalizing procurement decisions.
Selection Notes
Select this component when low current filtering is required for DC lines. The 150 mA rating suits applications with minimal power consumption. Consider the 7.5 Ohm DC resistance impact on voltage drop. Verify that the operating temperature range meets environmental conditions. Compare physical size constraints against available board space.
Part Context
The ST-110 series consists of common mode chokes manufactured by KEMET Corporation. These components are part of a broader family of passive filters designed for electromagnetic compatibility. The ST-110BV variant specifically targets through-hole assembly processes, providing reliable performance in compact electronic designs requiring noise attenuation.
Replacement Considerations
Consult official KEMET documentation for verified substitute part numbers within the ST-110 series or equivalent product lines. Ensure any replacement matches the 150 mA current rating, 7.5 Ohm resistance, and through-hole package type. Verify dimensional compatibility and electrical characteristics before substitution.
