- Supports high-temperature operation up to 120°C
- Designed for through-hole PCB mounting
Applications
- AC power input filtering
- Electromagnetic interference suppression in consumer electronics
- Industrial control equipment power stages
Procurement Notes
Verify the specific suffix M07680 against the official KEMET datasheet to confirm the 68 mH inductance and 0.7 A current rating. Ensure the package type matches the required through-hole footprint dimensions. Confirm compliance with RoHS directives if applicable to your manufacturing process. Cross-reference the manufacturer part number to avoid confusion with similar series variants.
Selection Notes
Select this component when a 68 mH inductance is required for common mode noise reduction at currents up to 700 mA. The wide operating temperature range makes it suitable for environments exceeding standard industrial limits. Verify that the physical dimensions fit the available PCB space and that the through-hole termination style aligns with the assembly method.
Part Context
This component belongs to the KEMET SSR21NHS-M series of AC line filters. These chokes are engineered for general-purpose electromagnetic interference suppression in AC circuits. The series offers various inductance values tailored for different current ratings and noise profiles, providing a standardized solution for power line conditioning across multiple electronic product categories.
Replacement Considerations
The UALS21H0768000 is listed as an alternative designation for this component. Verify electrical parameters such as inductance, current rating, and physical dimensions before substitution. Ensure the replacement part meets the same thermal and voltage specifications required by the original design.
