Overview
The SFJNL3K00221MC0 is a Knowles Syfer EMI feedthrough filter capacitor from the SFJN series. It features a capacitance of 220 pF with a tolerance of ±20%. The component has a DC voltage rating of 3 kVDC and supports a maximum DC current of 10 A. It utilizes C0G (NP0) dielectric material for stable performance across an operating temperature range of -55°C to +125°C. The physical package includes M6 x 0.75 threading, with a diameter of 9.8 mm, length of 9.4 mm, and lead wire diameter of 1 mm.
Feature Summary
- Provides electromagnetic interference suppression through integrated LC filtering architecture
- Features threaded mounting interface for secure panel installation
- Maintains capacitance stability using C0G dielectric material
Applications
- High-voltage power supply input filtering
- Industrial control system EMI protection
- Medical equipment signal conditioning
Procurement Notes
Verify the specific suffix code against official datasheets to confirm terminal configuration and sealing type. Ensure the M6 thread pitch matches the application panel requirements. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.
Selection Notes
Select this component when high voltage isolation and significant current handling are required in a compact form factor. The 3 kVDC rating and 10 A current capacity distinguish it from lower-rated feedthrough capacitors. Verify that the M6 threading fits the mechanical constraints of the enclosure design.
Part Context
This part belongs to the SFJN series of EMI feedthrough filters manufactured by Knowles Syfer. These components are designed for applications requiring robust noise suppression in high-voltage environments. The series offers various capacitance values and voltage ratings to suit different circuit protection needs.
