- Utilizes through-hole bobbin construction for PCB integration
- Designed for compact low-profile installation
Applications
- AC line input filtering
- EMI suppression in power supplies
- General electronic equipment noise reduction
Procurement Notes
Verify the specific suffix 'M' against the official KEMET datasheet to confirm exact electrical tolerances and material specifications. Ensure the ordering part number matches the required current rating and inductance values precisely. Cross-reference the manufacturer's latest documentation for any potential product changes or obsolescence notices before finalizing procurement decisions.
Selection Notes
Select this component when a 120 mH inductance at 600 mA is required for common mode noise attenuation. The through-hole package suits standard PCB layouts requiring robust mechanical anchoring. Verify that the operating temperature range of -25°C to +120°C aligns with the environmental conditions of the target application circuit.
Part Context
This component belongs to the KEMET SSR21NH-M series of AC line filters. These filters are characterized by their compact size and lightweight design, intended for efficient EMI suppression in single-phase applications. The series offers various inductance and current ratings to accommodate different power line requirements while maintaining a consistent form factor for board space optimization.
Replacement Considerations
SSR21NV-M061200 shares identical electrical parameters including 120 mH inductance and 600 mA current rating. Verify physical pin compatibility and housing dimensions before substitution to ensure mechanical fit within the existing assembly constraints.
