Overview
The KEMET SU9HF-05050 is a high-frequency common mode filter choke from the SU-9HF series, designed for AC line filtering applications. It features a radial through-hole termination and utilizes proprietary 7H ferrite material to provide effective noise suppression in the frequency range of ≥ 150 kHz. The component offers an inductance of 5 mH at a test frequency of 1 kHz, with a maximum DC current rating of 500 mA and a maximum DC resistance of 1.3 ohms. It operates within a temperature range of -25°C to +120°C and has physical dimensions of 17 mm in diameter.
Feature Summary
- Utilizes proprietary 7H ferrite material for high-frequency noise attenuation
- Designed for AC line filtering with radial through-hole mounting
- Suitable for operation in environments requiring wide temperature stability
Applications
- AC line input filtering for electronic equipment
- High-frequency common mode noise suppression in power supplies
- EMI reduction in consumer electronics and industrial control systems
Procurement Notes
Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters such as inductance tolerance and DC resistance values. Ensure that the operating temperature range and current ratings align with the thermal design of the target application. Cross-reference the part number with official KEMET resources to validate availability and compliance with relevant standards.
Selection Notes
Select this component when high-frequency common mode noise suppression is required for AC lines up to 250 VAC. Consider the 500 mA current rating and 1.3 ohm DC resistance for circuit compatibility. The radial package and 17 mm diameter should fit the available PCB space and mounting constraints. Evaluate the -25°C to +120°C operating range against environmental conditions.
Part Context
The SU9HF-05050 belongs to the KEMET SU-9VF/9HF series of common mode chokes. This series is characterized by its use of specialized ferrite materials optimized for high-frequency performance. These components are typically used in applications where compact size and efficient noise filtering are critical, providing a reliable solution for EMI mitigation in power circuits.
Replacement Considerations
Consult official KEMET documentation or authorized distributors for verified substitute part numbers. Do not assume interchangeability based on similar specifications alone; verify pinout, inductance, current rating, and physical dimensions against the original design requirements.
