Overview
The KEMET SSR21H-13120 is a single-phase AC line filter belonging to the SSR21H series, designed for through-hole mounting. It functions as a high impedance common mode choke with an inductance of 12 mH at 10 kHz and a maximum DC resistance of 240 mOhms. The component supports a rated current of 1.3 A and operates within a voltage range up to 250 VAC. Physical dimensions are 23.0 mm in length and width, with a height of 14.5 mm. It complies with RoHS standards and maintains an insulation resistance of at least 100 MΩ.
Feature Summary
- Provides high impedance common mode filtering for AC line applications
- Compact, low profile, and lightweight construction suitable for space-constrained designs
- Through-hole mounting configuration for secure PCB integration
Applications
- Single-phase AC power line EMI suppression
- Electronic equipment requiring common mode noise reduction
- Power supply input filtering stages
Procurement Notes
Verify the specific part number SSR21H-13120 against official KEMET documentation to confirm electrical parameters such as 12 mH inductance and 1.3 A rating. Ensure compatibility with through-hole assembly processes and check for any design life notices or obsolescence warnings associated with this component series before procurement.
Selection Notes
Select this component when a single-phase AC filter with 12 mH inductance and 1.3 A current handling is required. Consider the 23.0 x 23.0 x 14.5 mm footprint and through-hole termination style. Verify that the operating temperature range and voltage ratings meet the system requirements for the intended application environment.
Part Context
The SSR21H-13120 is part of the KEMET SSR21H Series, which comprises compact AC line filters. This series is characterized by its high impedance type design, offering effective common mode noise attenuation. The components are engineered for reliability in standard electronic assemblies, providing a balance between performance and physical size for AC line filtering tasks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult KEMET technical support or updated distributor catalogs for potential cross-references or newer generation equivalents if this specific part is unavailable.
