Overview
The KEMET ST-202 is a two-line common mode choke designed for through-hole mounting. It features a maximum DC resistance of 40 milliohms and supports a rated current of 1A with a 50V DC rating. The component exhibits an impedance of 600 Ohms at 100 MHz. Its physical dimensions are 0.630 inches in diameter and height, utilizing a vertical package without a base and four pins. The operating temperature range spans from -20°C to 75°C.
Feature Summary
- Two-line configuration for differential signal filtering
- Through-hole toroidal construction for mechanical stability
- Low DC resistance to minimize power loss
- High impedance performance at 100 MHz
Applications
- DC line filtering in electronic circuits
- Common mode noise suppression in data lines
- Power supply input stages requiring EMI reduction
Procurement Notes
Verify the specific manufacturer part number against official KEMET documentation to ensure compatibility with design requirements. Confirm that the through-hole package dimensions and pin configuration match the target PCB layout. Check RoHS compliance status if restricted substances are a constraint. Ensure the rated current and voltage parameters meet the operational demands of the application circuit.
Selection Notes
Select this component when a two-line common mode choke with low DC resistance is required for through-hole assembly. The 1A current rating and 600 Ohm impedance at 100 MHz suit applications needing moderate noise suppression. Verify that the 50V DC rating aligns with the system voltage. Consider the physical size constraints as the component has a cylindrical form factor with a 0.630-inch diameter.
Part Context
The ST-202 belongs to the KEMET ST series of common mode chokes. This series offers various characteristics for different filtering needs. The ST-202 specifically provides a balance of low DC resistance and high impedance for effective noise attenuation in two-line configurations.
Replacement Considerations
The ST-202A is a related variant within the same series but features a higher DC resistance of 50 milliohms and a lower operating temperature range of -20°C to 65°C. Verify electrical and thermal specifications before substitution.
