Overview
The KEMET SSHB21H-R07700 is a dual mode common mode choke designed for through-hole mounting. It features an inductance of 70 mH at 10 kHz and supports a DC current rating of 700 mA with a maximum DC resistance of 1.16 Ohms. The component operates within a temperature range of -40°C to +85°C and is rated for 250 VAC. Its physical dimensions include a diameter of 26 mm and a lead spacing of 21 mm, utilizing 0.8 mm diameter leads.
Feature Summary
- Dual mode functionality combining normal mode countermeasures with common mode filtering
- Hybrid coil construction optimized for AC line filter applications
- Through-hole radial leaded package for robust mechanical mounting
Applications
- AC line filtering in electronic equipment
- Common mode noise suppression in power supplies
- EMI reduction in industrial control systems
Procurement Notes
Verify the specific lot marking R07 on the component body to confirm authenticity against official KEMET documentation. Ensure the procurement specification matches the 70 mH inductance tolerance and 700 mA current rating requirements. Confirm that the through-hole footprint aligns with the 21 mm lead spacing and 26 mm diameter constraints for the target PCB design.
Selection Notes
Select this component when dual mode filtering is required for AC lines up to 250 VAC. The 700 mA current rating suits moderate power applications where space allows for a 26 mm diameter through-hole mount. Consider the 1.16 Ohm DC resistance impact on circuit efficiency during initial design phases.
Part Context
This part belongs to the KEMET SSHB series of hybrid coils. These components are engineered to provide both common mode and normal mode attenuation in a single package. The series is characterized by high impedance characteristics suitable for commercial grade EMI suppression tasks.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing footprints if considering alternative manufacturers.
