Overview
The KEMET SSR21NV-M031900 is a through-hole common mode filter choke designed for AC line filtering applications. It features an inductance of 190 mH measured at 10 kHz and supports a maximum DC current of 300 mA. The component is rated for 250 VAC and exhibits a maximum DC resistance (DCR) of 2.9 Ohms. It operates within a temperature range of -25°C to +120°C. The physical dimensions are 22.00 mm in length, 16.00 mm in width, and 27.00 mm in height, utilizing a vertical package with four pins.
Feature Summary
- Provides common mode noise suppression for AC power lines
- Supports high-temperature operation up to 120°C
- Designed for reliable through-hole PCB mounting
Applications
- AC line input filtering in electronic equipment
- EMI/RFI suppression in power supply circuits
- Common mode noise reduction in consumer electronics
Procurement Notes
Verify the specific suffix M031900 against official KEMET documentation to confirm the exact inductance and current ratings. Ensure compatibility with existing PCB footprints, as the SSR21NV series utilizes a vertical through-hole configuration. Confirm RoHS compliance status directly from the manufacturer's datasheet before integration into regulated products.
Selection Notes
Select this component when a 190 mH inductance at 10 kHz is required for common mode noise attenuation. The 300 mA current rating suits low-power AC line applications. Verify that the 2.9 Ohm DCR meets system loss requirements. Ensure the operating environment stays within the specified -25°C to +120°C temperature range for optimal performance.
Part Context
This part belongs to the KEMET SSR21NV-M series of AC line filters. These components are engineered for general-purpose EMI suppression in single-phase AC circuits. The series offers various inductance and current combinations to suit different power levels while maintaining a compact vertical form factor suitable for dense PCB layouts.
Replacement Considerations
The alias UALM21V0319000 may serve as a cross-reference identifier. Verify electrical equivalence with other 190 mH, 300 mA common mode chokes if substitution is necessary. Ensure replacement parts match the 22x16x27 mm footprint and through-hole pin configuration.
