Overview
The KEMET SSR21NV-07405 is a through-hole common mode choke designed for AC line filtering applications. It features an inductance of 40.5 mH and supports a maximum DC current of 0.7 A. The component has a minimum DC resistance of 0.61 mOhms and operates within a temperature range of -25°C to +120°C. Rated for 250 VAC, it utilizes proprietary S15H ferrite material with high permeability. The physical dimensions are 3.5 mm in length, 16 mm in width, and 27 mm in height.
Feature Summary
- Utilizes proprietary S15H ferrite material for high permeability
- Achieves large inductance values through a non-divided bobbin design
- Offers a compact, low-profile form factor suitable for space-constrained PCBs
Applications
- AC line noise suppression
- Common mode interference filtering
- Power supply input stages
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct electrical parameters and packaging configuration. Confirm that the procurement channel provides valid traceability documentation. Check for any regional shipping restrictions or compliance certifications required for the target market before finalizing orders.
Selection Notes
Select this component when high inductance is required in a compact through-hole package. The S15H ferrite material offers advantages in specific frequency ranges compared to standard materials. Ensure the operating current does not exceed 0.7 A and the voltage rating aligns with the 250 VAC system requirements.
Part Context
This part belongs to the SSR21NV series of AC line filters from KEMET. The series is characterized by its use of specialized ferrite cores and non-divided bobbins to maximize inductance density. These components are engineered for reliable performance in industrial and commercial power electronics environments requiring robust EMI mitigation.
Replacement Considerations
Consult the official KEMET replacement guide for verified substitutes. Cross-referencing requires matching inductance, current rating, and physical footprint constraints.
