Overview
The KEMET SCR39XV-180-2R0A015JH is an automotive-grade common mode choke from the SCR-XV series, designed for single-phase applications. It features a ferrite core and radial leaded construction with a diameter of 53 mm. The component provides an inductance of 3 mH at 100 kHz and supports a DC current rating of 18 A. Its maximum DC resistance is 5.98 mOhm (5980 µohm). It operates within a temperature range of -40°C to 120°C and withstands up to 1000 V.
Feature Summary
- Automotive grade qualification for reliable performance in vehicle environments
- Ferrite core construction optimized for high-frequency noise suppression
- Radial leaded package design facilitating through-hole mounting
Applications
- Single-phase AC/DC power input filtering
- Automotive electronic control unit (ECU) power lines
- Common mode noise reduction in high-current automotive circuits
Procurement Notes
Verify the specific inductance value against official datasheets, as sources vary between 2.6 mH and 3 mH. Confirm the operating temperature limit is 120°C rather than 150°C, which applies to different series variants. Ensure the part number suffix matches the required tolerance and packaging specifications for your assembly process.
Selection Notes
Select this component when high current handling of 18 A is required alongside significant common mode attenuation. The 1000 V rating suits high-voltage automotive systems. Compare the 5.98 mOhm DCR against thermal constraints in your design. Ensure the radial leaded form factor fits the PCB layout requirements compared to surface-mount alternatives.
Part Context
This part belongs to the SCR-XV series of common mode chokes manufactured by KEMET. The series is characterized by its automotive focus and robust ferrite core technology. It is distinct from the SCF-XV series, which may offer higher temperature ratings but differs in specific electrical characteristics and physical dimensions.
Replacement Considerations
The SCF39XV-180-2R0A015JH is a related variant within the same product family. Note that the SCF series may support a higher maximum operating temperature of 150°C compared to the 120°C limit of the SCR series. Verify inductance and current ratings before substitution.
