Overview
The KEMET SSR21NV-M07890 is a through-hole common mode choke filter designed for AC line applications. It features an inductance of 89 mH and supports a maximum DC current of 700 mA. The component has a maximum DC resistance of 1.05 Ohms and operates within a temperature range of -40°C to +120°C. Rated for 250 VAC, it utilizes a single-channel configuration with a test frequency of 10 kHz. Physical dimensions include a height of 14.5 mm, width of 23 mm, and length of 3.5 mm, weighing approximately 13 grams.
Feature Summary
- Provides common mode noise suppression for AC power lines
- Supports high-temperature operation up to 120°C
- Designed for PCB mounting via through-hole termination
Applications
- AC line filtering in electronic equipment
- Noise reduction in power supply inputs
- EMI suppression in consumer electronics
Procurement Notes
Verify the specific suffix M07890 against official KEMET documentation to confirm exact electrical tolerances and pinout configurations. Ensure compatibility with existing PCB footprints, as physical dimensions are critical for through-hole assembly. Confirm RoHS compliance status directly from the manufacturer's datasheet before integration into regulated products.
Selection Notes
Select this component when an 89 mH inductance value is required for common mode noise attenuation at 10 kHz. The 700 mA current rating suits moderate power applications. Consider the 1.05 Ohm DC resistance for voltage drop calculations. The wide operating temperature range allows use in environments exceeding standard industrial limits.
Part Context
This part belongs to the KEMET SSR21NV-M series of common mode chokes. These components are engineered for AC line filtering applications requiring robust noise suppression. The series offers various inductance and current ratings to suit different power levels while maintaining a standardized form factor for easy integration into printed circuit board designs.
Replacement Considerations
SSR21NH-M07890 shares identical electrical specifications including 89 mH inductance and 700 mA rating. Verify mechanical footprint differences, as the NH variant may have distinct dimensional constraints compared to the NV series.
