SCR31HA-070-1R1A039JH-P

Overview

The KEMET SCR31HA-070-1R1A039JH-P is a radial leaded common mode choke designed for AC line filtering applications. It features an inductance of 3.85 mH at 10 kHz and supports a current rating of 7 A. The component exhibits a direct current resistance (DCR) of 24 mOhms and is rated for 250 V operation. This through-hole filter provides effective noise suppression for single-phase power lines.

Feature Summary

• Provides common mode noise attenuation for AC power lines
• Radial leaded construction facilitates through-hole mounting
• Engineered for high current handling capabilities

Applications

• AC line input filtering
• Power supply EMI suppression
• Single-phase equipment noise reduction

Procurement Notes

Verify the complete part number including suffixes to ensure correct inductance and current ratings. Confirm package type matches design requirements. Check manufacturer documentation for RoHS compliance status and operating temperature range specifications before integration.

Selection Notes

Select this component when designing circuits requiring common mode chokes with specific inductance values around 3.85 mH. Ensure the PCB layout accommodates radial leads and sufficient clearance for the 250 V rating. Evaluate thermal performance under continuous 7 A load conditions.

Part Context

This component belongs to the KEMET SCR-H series of radial leaded common mode chokes. The series offers various inductance and current combinations for general-purpose AC line filtering. These filters are commonly used in consumer electronics and industrial power supplies to meet electromagnetic compatibility standards.

Replacement Considerations

Cross-reference with other KEMET SCR-H variants or equivalent common mode chokes from manufacturers like TDK or Murata. Verify that substitute components match the 3.85 mH inductance, 7 A current rating, and 24 mOhm DCR specifications.
