Overview
The KEMET SH-211 is a through-hole common mode choke from the SH series, designed for DC line filter applications. It features an inductance of 0.5 µH measured at a test frequency of 100 kHz and supports a continuous current rating of 3 A. The component exhibits a low DC resistance of 18 mΩ and is rated for voltages up to 150 VAC. Its physical dimensions are limited to a maximum length of 14 mm, width of 12 mm, and height of 9.5 mm, with lead lengths specified at 4 mm ±1 mm.
Feature Summary
- Provides common mode noise suppression for DC power lines
- Utilizes nickel-zinc core material for effective interference mitigation
- Designed for through-hole mounting on printed circuit boards
Applications
- DC power line filtering circuits
- Electromagnetic interference (EMI) suppression
- General purpose noise reduction in electronic assemblies
Procurement Notes
Verify the specific voltage rating requirements against the application's peak operating conditions, as sources cite both 150 VAC and 250 VAC. Confirm that the 3 A current rating aligns with the circuit's load profile. Ensure the through-hole package dimensions fit the target PCB layout constraints before finalizing procurement decisions.
Selection Notes
Select this component when a compact, low-inductance solution is required for high-current DC lines. The 18 mΩ DCR minimizes power loss compared to higher-resistance alternatives. Consider the 100 kHz test frequency relevance for the specific noise spectrum being filtered. Evaluate mechanical stability needs for through-hole versus surface mount options if space permits.
Part Context
The SH-211 belongs to KEMET's SH series of common mode chokes. This series offers various inductance values and current ratings tailored for different filtering needs. The SH-211 specifically targets applications requiring moderate inductance with high current handling capabilities in a standard through-hole form factor.
Replacement Considerations
Cross-reference with other SH-series part numbers for adjusted inductance or current ratings. Verify pin compatibility and physical footprint equivalence when substituting with components from other manufacturers offering similar through-hole common mode chokes.
