Overview
The KEMET SSRH7H-M15043 is a through-hole common mode choke from the SSRH7H-M series, designed for AC line filtering. It features an inductance of 4.3 mH and a maximum DC current rating of 1.5 A. The component has a maximum DC resistance of 0.14 Ω and operates within a temperature range of -25°C to +120°C. Rated for 250 VAC, it utilizes manganese-zinc ferrite core material and measures 18 mm in length, 14.5 mm in depth, and 12 mm in height.
Feature Summary
- Utilizes proprietary S18H high-permeability ferrite core material for optimized magnetic performance.
- Features a split bobbin structure that provides high impedance across a wide frequency range.
- Designed with a compact, low-profile form factor suitable for space-constrained applications.
Applications
- Audio-visual equipment
- Office automation devices
- Digital equipment
- Small power supplies
Procurement Notes
Verify the specific manufacturer datasheet for the SSRH7H-M15043 to confirm final electrical tolerances and mechanical dimensions. Ensure the selected variant matches the required current rating and inductance values for the target circuit design. Cross-reference official documentation to validate compliance standards and operating temperature limits before integration.
Selection Notes
Select this component when high impedance at common mode noise frequencies is required for low-to-medium current AC lines. The 1.5 A rating suits applications where space is limited but significant noise suppression is necessary. Consider the through-hole mounting requirement and physical dimensions against available PCB real estate during the design phase.
Part Context
This part belongs to the KEMET SSRH7H-M series of gear-type common mode chokes. These components are engineered for low-current applications requiring high inductance in a small volume. The series leverages specialized ferrite materials to achieve superior noise cancellation characteristics compared to standard air-core or generic ferrite alternatives.
Replacement Considerations
Publicly confirmed substitute part numbers for the SSRH7H-M15043 were not identified in the provided source data. Verify compatibility with alternative manufacturers by matching inductance, current rating, and physical footprint specifications.
