Overview
The ST-202A is a two-line common mode choke manufactured by KEMET, designed for through-hole mounting. It features a rated DC voltage of 50V and a maximum current rating of 1A. The component exhibits a DC resistance (DCR) of 50 milliohms and provides an impedance of 600 Ohms at 100 MHz. Its physical dimensions are 16.00mm in length, 10.50mm in width, and a maximum height of 10.50mm. The operating temperature range spans from -20°C to +65°C.
Feature Summary
- Utilizes proprietary Manganese-Zinc (Mn-Zn) and Nickel-Zinc (Ni-Zn) ferrite materials for effective noise suppression
- Provides high dielectric strength with a withstand voltage of 500 VDC between lines for one minute
- Designed for vertical installation with four pins for secure through-hole PCB attachment
Applications
- DC line filtering in low-voltage electronic circuits
- Common mode noise suppression for data and power lines
- EMI reduction in industrial control systems
Procurement Notes
Verify the specific manufacturer datasheet for the ST-202A to confirm current availability and compliance status. Ensure that the required impedance characteristics at 100 MHz align with the target application's noise profile. Confirm that the 50V DC rating and 1A current capacity meet the circuit requirements before procurement.
Selection Notes
Select this component when a through-hole solution is required for low-voltage DC applications. The 50mOhm DCR ensures minimal voltage drop, while the 600 Ohm impedance at 100 MHz targets high-frequency interference. Verify that the -20°C to +65°C operating range suits the environmental conditions of the intended deployment.
Part Context
The ST-202A belongs to the ST series of common mode chokes produced by KEMET. This series focuses on providing reliable EMI filtering solutions using specialized ferrite materials. The component is distinct from KEMET's capacitor products, serving specifically as a passive filter for signal and power integrity in electronic assemblies.
Replacement Considerations
Publicly confirmed substitute part numbers for the ST-202A were not identified in the provided documentation. Cross-referencing with other KEMET ST-series components or equivalent common mode chokes from other manufacturers requires independent verification of electrical and mechanical specifications.
