Overview
The Knowles Syfer 1206J2000222MJTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a 1206 (3216 metric) case size with a capacitance of 2200 pF and a DC voltage rating of 200V. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across varying conditions. It offers a tolerance of ±20% and includes an integrated nickel barrier structure to enhance reliability in harsh environments.
Feature Summary
- Integrated feed-through architecture providing effective electromagnetic interference filtering within a compact SMD footprint
- Nickel barrier construction designed to improve resistance against moisture ingress and environmental degradation
- C0G/NP0 dielectric composition ensures minimal capacitance variation over temperature and voltage changes
Applications
- High-frequency signal line filtering in communication equipment
- Power supply input/output decoupling in automotive electronics
- EMI suppression circuits in industrial control systems
Procurement Notes
Verify the specific ordering suffix to confirm the presence of the nickel barrier feature, as standard variants may differ. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected packaging format matches production line requirements. Cross-reference the full part number with the latest datasheet to validate electrical ratings and mechanical dimensions for your specific application design.
Selection Notes
Select this component when high-frequency noise suppression is required in space-constrained designs. The feed-through topology allows for direct trace routing, reducing parasitic inductance compared to standard MLCCs. Consider the nickel barrier option if operating in humid or corrosive environments. Verify that the 200V rating and 2200pF value align with the circuit's impedance and voltage requirements.
Part Context
This component belongs to the Knowles Syfer Syfer® series of advanced ceramic capacitors. The series emphasizes reliability and performance in demanding applications. The 1206J prefix indicates the case size and general product family, while the specific suffix denotes the unique electrical and structural characteristics, including the feed-through design and barrier coating.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's official substitution guide or contact technical support for verified alternatives that match the feed-through configuration and nickel barrier specifications.
