DS1-40-0003

Common Mode Chokes Overview

The DS1-40-0003 is a leaded power inductor from Schurter, classified as a storage choke and common mode choke. It features radial termination for PCB mounting. Key electrical parameters include an inductance of 200 uH, a maximum DC current rating of 4 A, and a maximum DC resistance of 55 mOhms. The component operates within a temperature range of -40 C to +125 C and has a self-resonant frequency of 1.5 MHz.

Common Mode Chokes Feature Summary

• Functions as both a storage choke and a two-line common mode choke for noise suppression.
• Designed for through-hole PCB mounting with radial leads.
• Capable of handling high DC currents up to 4 A with low resistance.

Common Mode Chokes Applications

• Power supply input filtering
• Common mode noise suppression in two-line circuits
• DC-DC converter storage applications

Common Mode Chokes Procurement Notes

Verify the specific datasheet version (e.g., DS1-40-0003(1).pdf or (2).pdf) before procurement, as multiple documents exist. Confirm that the radial lead configuration matches the target PCB footprint. Ensure the application environment stays within the specified -40 C to +125 C operating temperature range to maintain performance integrity.

Common Mode Chokes Selection Notes

Select this component when a combined storage and common mode filtering solution is required. The 200 uH inductance and 4 A current rating suit moderate-power applications. Compare against the DS1-175-0003 if lower current (1 A) or different impedance characteristics are needed. Verify the 55 mOhm DCR fits the efficiency requirements of the circuit design.

Common Mode Chokes Part Context

This part belongs to the DS series of power inductors manufactured by Schurter. These components are designed for robust performance in industrial and consumer electronics. The DS1-40-0003 specifically addresses needs for compact, leaded magnetic components that provide both energy storage and electromagnetic interference reduction in a single package.

Common Mode Chokes Replacement Considerations

The DS1-175-0003 is a related Schurter model but is rated for only 1 A maximum DC current. Substitution requires verifying that the reduced current capacity meets the system's operational demands. No other direct substitutes are confirmed in the provided documentation.
