Overview

The Schurter 3-143-899 is a compensated high-current suppression choke designed for two-line applications. It features an inductance of 24.3 mH and supports a continuous current rating of 50 A. The component has a DC resistance of 2.5 mΩ and is rated for 800 V DC and 250 V AC. It utilizes through-hole radial leads for mounting.

Feature Summary

Compensated design ensures low impedance under load conditions
High current handling capability for demanding power circuits
Dual voltage ratings support diverse system architectures

Applications

DC link filtering in photovoltaic inverters
EMI suppression in industrial power supplies
Common mode noise reduction in motor drives

Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and thermal characteristics. Ensure the selected variant matches the required insulation class and safety certifications for the target market. Cross-reference the manufacturer part number with official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when high current compensation is required to maintain inductance stability. Consider the 2.5 mΩ resistance for efficiency calculations in low-voltage, high-amperage systems. Evaluate the 800 V DC rating against peak bus voltages to ensure adequate safety margins.

Part Context

This component belongs to the DKUH series of compensated chokes from Schurter. These devices are engineered for high-efficiency power conversion environments where magnetic saturation must be minimized. The series is commonly integrated into renewable energy and industrial automation hardware.
