Procurement Notes
Verify the specific part number SH-312 against official KEMET documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with required current and voltage specifications for the target application. Check for RoHS compliance status as indicated in the manufacturer datasheet. Confirm lead availability and packaging details directly with authorized distributors or the manufacturer.
Selection Notes
Select this component when common mode noise attenuation is required for DC or low-frequency signal lines. The 3 A current rating and low DC resistance make it suitable for power-sensitive applications. Consider the through-hole form factor if surface mount options are not feasible. Evaluate thermal performance within the specified -25 °C to 80 °C range for the intended environment.
Part Context
The SH-312 belongs to KEMET's SH series of common mode chokes. This series focuses on providing effective electromagnetic interference (EMI) suppression for various electronic systems. The component utilizes a through-hole technology, ensuring robust mechanical attachment to printed circuit boards. It is engineered to handle significant current loads while maintaining low insertion loss.
Replacement Considerations
Consult official KEMET substitution guides for verified alternatives. Cross-reference inductance, current rating, and DC resistance values when evaluating potential substitutes. Ensure physical footprint compatibility if board space is constrained.
