Overview
The KEMET SS21VB-R080069 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 6.9 mH measured at 1 kHz and supports a maximum DC current of 800 mA. The component has a maximum DC resistance of 471 mOhms and operates within a temperature range of -40°C to +120°C. Rated for 250 VAC and 500 VAC, it utilizes proprietary core materials including metal, manganese-zinc ferrite, nano-crystal, and nickel-zinc ferrite.
Feature Summary
- Provides common mode noise suppression for AC power lines
- Utilizes proprietary multi-material core technology for enhanced performance
- Designed for robust operation across extended industrial temperature ranges
Applications
- AC line input filtering in electronic equipment
- Noise reduction in power supply circuits
- EMI suppression in consumer and industrial electronics
Procurement Notes
Verify the specific voltage rating requirements against the datasheet, as sources indicate both 250 VAC and 500 VAC ratings. Confirm the inductance value of 6.9 mH matches the design specifications. Ensure the through-hole mounting style fits the PCB layout constraints. Check RoHS compliance status if required by project standards.
Selection Notes
Select this component when high inductance is required for effective common mode noise attenuation at low currents. The wide operating temperature range makes it suitable for harsh environments. Compare the 471 mOhm DC resistance against allowable power loss limits in the circuit design. Consider the physical dimensions for board space allocation.
Part Context
This part belongs to the KEMET SS21VB series of common mode chokes. These components are engineered for AC line filter applications requiring reliable EMI suppression. The series offers various inductance values and current ratings to suit different power levels while maintaining consistent mounting and electrical characteristics.
