Overview
The Knowles Syfer 1812J2000332MJTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 3300 pF with a ±20% tolerance and utilizes C0G (NP0) dielectric material. The component is rated for a DC voltage of 200 V and supports a continuous current of 50 mA. Housed in an 1812 (4532 metric) package, it operates within a temperature range of -55°C to +125°C.
Feature Summary
- Integrates feed-through architecture to provide effective electromagnetic interference filtering directly on the signal path.
- Utilizes C0G (NP0) dielectric material to ensure stable capacitance performance across varying temperatures and voltages.
- Supports high continuous current handling capabilities suitable for power line applications.
Applications
- Electromagnetic interference filtering in high-frequency circuits
- Power supply input stages requiring integrated decoupling
- Signal conditioning in sensitive electronic systems
Procurement Notes
Verify the complete part number including the suffix to confirm the specific termination and packaging configuration. Ensure compatibility with the intended PCB footprint and thermal management requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.
Selection Notes
Select this component when simultaneous RF filtering and power delivery are required in a single surface-mount device. The feed-through design reduces parasitic inductance compared to standard MLCCs. Consider the 50 mA current rating and 200 VDC voltage limit against circuit operating conditions to ensure reliable long-term performance.
Part Context
This component belongs to the Knowles Syfer feed-through capacitor series, which combines the benefits of traditional ceramic capacitors with coaxial feed-through structures. These devices are engineered for high-performance environments where space constraints and EMI suppression are critical design factors.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific model were not identified in the provided source data. Verify pinout and electrical specifications before considering alternative manufacturers or generic equivalents.
