RL-9750-2HL-12,0

Common Mode Chokes Overview

The RL-9750-2HL-12,0 is a through-hole AC line filter manufactured by Renco Electronics. It functions as a two-line common mode choke with an inductance of 12 mH measured at 10 kHz. The component supports a maximum current rating of 1.2 A and features a direct current resistance (DCR) of 300 mOhm. Designed for safety applications, it filters noise between the line and neutral connections in low to medium power AC-DC power supplies.

Common Mode Chokes Feature Summary

• Designed for line-to-neutral safety filtering
• Through-hole mounting configuration
• Two-line common mode choke architecture

Common Mode Chokes Applications

• Low power AC-DC power supplies
• Medium power AC-DC power supplies
• Line to neutral safety filtering circuits

Common Mode Chokes Procurement Notes

Verify the specific suffix '12,0' corresponds to the 12 mH inductance value when sourcing. Confirm that the package type matches the required through-hole footprint for your PCB layout. Ensure the 1.2 A current rating meets the operational requirements of your target circuit. Cross-reference the manufacturer part number with official Renco or Standex documentation to avoid confusion with similar series variants.

Common Mode Chokes Selection Notes

Select this component when designing AC-DC power supplies requiring common mode noise suppression on both line and neutral conductors. The 12 mH inductance provides effective filtering for standard EMI frequencies. Verify that the physical size accommodates the available board space for through-hole assembly. Consider the 300 mOhm DCR impact on voltage drop if operating near the 1.2 A limit.

Common Mode Chokes Part Context

This part belongs to the RL-9750-2HL series of through-hole AC line filters from Renco Electronics. The series includes various inductance values tailored for different power levels. Renco Electronics was acquired by Standex Electronics in 2020, maintaining its legacy in custom inductors and chokes. This specific model targets safety-critical filtering applications in consumer and industrial electronics.

Common Mode Chokes Replacement Considerations

Check for exact inductance and current rating matches in the RL-9750-2HL series. Verify pin compatibility and physical dimensions before substituting. No direct substitute part numbers are publicly confirmed for this specific variant.
