Overview
The Knowles Syfer SFJEC3K00151MC1 is an axial feedthrough capacitor with a capacitance of 150 pF and a voltage rating of 3 kV. It features a C0G/NP0 dielectric for stable performance across temperatures ranging from -55°C to +125°C. The component utilizes a flange end seal construction, providing robust environmental protection and high reliability in demanding applications.
Feature Summary
- Axial feedthrough design for effective EMI filtering
- Flange end seal construction for environmental protection
- C0G/NP0 dielectric ensures high stability and low loss
Applications
- High-voltage power supply filtering
- EMI suppression in sensitive electronic circuits
- Industrial control systems requiring reliable feedthrough capacitors
Procurement Notes
Verify the specific package dimensions and mounting requirements against your PCB or chassis design before ordering. Confirm that the 3 kV rating aligns with your system's peak voltage stresses. Ensure compatibility with your assembly process for axial components. Check for any specific handling instructions related to the flange seal integrity during installation.
Selection Notes
Select this component when high-frequency noise attenuation is required in high-voltage environments. The axial form factor simplifies mounting on panels or through holes. Consider the physical size constraints of the flange mount. Evaluate the thermal environment to ensure operation within the specified temperature range for optimal capacitance stability.
Part Context
This part belongs to the Syfer feedthrough capacitor series, designed for harsh environments. It complements surface-mount MLCCs by offering superior shielding and mechanical stability for panel-mounted applications. The axial configuration allows for direct connection to coaxial cables or busbars, enhancing signal integrity in high-noise scenarios.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify electrical equivalence and mechanical fit if considering alternatives from other manufacturers.
