PMC9539.254NL

Common Mode Chokes Overview

The PMC9539.254NL is a two-line common mode choke manufactured by Pulse Electronics, designed for through-hole mounting. It features an inductance of 250 µH and supports a DC current rating of 18 A. The component exhibits a DC resistance (DCR) of 2.7 mΩ and provides a common mode impedance of 750 Ω at a frequency of 1.6 MHz.

Common Mode Chokes Feature Summary

• Provides effective common mode noise suppression for two-line circuits
• Supports high current handling capabilities suitable for power applications
• Utilizes a through-hole radial leaded package for secure board attachment

Common Mode Chokes Applications

• Power supply input filtering
• EMI suppression in AC/DC converters
• Noise reduction in industrial control systems

Common Mode Chokes Procurement Notes

Verify the specific suffix '254' to confirm the 250 µH inductance and 18 A current rating, as the PMC9539 series includes variants with different electrical characteristics. Ensure the through-hole footprint dimensions match the target PCB layout. Confirm RoHS compliance status if required by project specifications.

Common Mode Chokes Selection Notes

Select this component when a 250 µH inductance and 18 A continuous current rating are required for common mode noise attenuation. The low DCR minimizes power loss in high-current paths. Consider the physical size constraints associated with the radial through-hole package during mechanical design.

Common Mode Chokes Part Context

This part belongs to the PMC9539.XXXNL series of THT common mode chokes from Pulse Electronics. The series offers various inductance and current ratings, distinguished by the numeric suffix in the part number. These components are engineered for robust performance in demanding power electronics environments.

Common Mode Chokes Replacement Considerations

Direct substitutes within the same series include PMC9539.903NL and PMC9539.164NL, though these differ in inductance and current ratings. Verify that any replacement matches the required 250 µH inductance and 18 A current capacity to ensure circuit compatibility.
