Overview
The KEMET SSHB21H-R12296 is a dual-mode common mode choke designed for through-hole mounting. It features an inductance of 29.6 mH and supports a DC current rating of 1.2 A with a maximum DC resistance of 0.49 ohms. The component operates within a voltage range of 250 VAC and functions across a temperature spectrum from -40°C to +120°C. Its physical dimensions include a maximum length of 26 mm, width of 23 mm, and height of 15.5 mm, with a lead spacing of 21 mm.
Feature Summary
- Dual-mode filtering capability for enhanced noise suppression
- Through-hole construction for robust mechanical stability
- High inductance value for effective common mode interference reduction
Applications
- AC line input filtering in power supplies
- Electromagnetic interference suppression in industrial equipment
- Noise mitigation in consumer electronics AC interfaces
Procurement Notes
Verify the specific suffix and series designation against official KEMET documentation to ensure compatibility with design requirements. Confirm that the through-hole footprint and lead spacing match the target PCB layout. Cross-reference the electrical ratings with system operating conditions to guarantee performance under load. Ensure sourcing channels provide authentic components with traceable manufacturing data.
Selection Notes
Select this component when high inductance is required for common mode noise attenuation in through-hole applications. The dual-mode characteristic offers versatility in handling both differential and common mode signals. Evaluate the thermal performance limits against the expected operating environment. Consider the physical size constraints relative to the enclosure design before finalizing the selection.
Part Context
This component belongs to the SSHB21H series of dual-mode chokes manufactured by KEMET. These devices are engineered for through-hole assembly, providing reliable performance in environments requiring robust electromagnetic interference filtering. The series is commonly utilized in applications where standard single-mode chokes may not suffice for complex noise profiles.
Replacement Considerations
Potential substitutes include parts from the UALSB2R1229600 alias group. Verify inductance, current rating, and physical dimensions before substitution. Ensure any alternative component meets the same dual-mode specifications and through-hole mounting requirements.
