Overview
The KEMET ST-101F2 is a through-hole common mode DC line filter designed for signal and power line noise suppression. It utilizes proprietary Manganese-Zinc (Mn-Zn) and Nickel-Zinc (Ni-Zn) ferrite materials within a toroidal coil structure. The component supports a maximum DC current of 200 mA with a typical DC resistance of 2.7 Ohms. It offers an impedance of 40 kOhms at standard test frequencies and withstands 500 VDC between lines for one minute. The operating temperature range spans from -20°C to +120°C, ensuring reliability in various electronic environments.
Feature Summary
- Utilizes proprietary Mn-Zn and Ni-Zn ferrite materials for effective noise attenuation
- Through-hole toroidal construction for robust mechanical stability
- High voltage isolation capability between lines
Applications
- Audio-visual equipment
- Home appliances
- Power supplies
- Office automation equipment
Procurement Notes
Verify the specific datasheet version for the ST-101F2 to confirm exact impedance curves and thermal derating characteristics. Ensure that the through-hole footprint dimensions match the target PCB layout constraints. Confirm RoHS compliance status if required by the final assembly specifications. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when common mode noise suppression is required for low-current DC lines up to 200 mA. The high impedance value makes it suitable for filtering high-frequency interference in sensitive audio or data circuits. Consider the through-hole termination style if surface mount options are not feasible or if higher mechanical strength is needed for the application environment.
Part Context
The ST-101F2 belongs to the KEMET ST series of common mode chokes. This series provides a range of through-hole and surface mount options for EMI suppression. The ST series is characterized by its use of specialized ferrite cores to achieve high performance in compact packages, catering to diverse industrial and consumer electronics needs.
Replacement Considerations
Check for direct substitutes within the KEMET ST series that match the 200 mA current rating and 40 kOhms impedance. Verify that any alternative component maintains the same through-hole package dimensions and voltage withstand capabilities to ensure physical and electrical compatibility.
