1206J1000333MJTE03

Overview

The Knowles Syfer 1206J1000333MJTE03 is a feed-through multilayer ceramic capacitor designed for surface-mount technology. It features a capacitance of 0.033 µF with a DC voltage rating of 100 V and a tolerance of ±5%. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a 1206 (3216 metric) package, it includes an integrated 50 mA fuse element within the center conductor structure.

Feature Summary

• Integrates a built-in fuse element within the center conductor for combined filtering and overcurrent protection capabilities.
• Utilizes C0G (NP0) dielectric material to maintain consistent capacitance values under varying thermal conditions.
• Features a three-pad surface-mount footprint design optimized for high-frequency noise suppression applications.

Applications

• High-frequency EMI/RFI filtering in sensitive electronic circuits
• Power supply input stages requiring integrated surge protection
• Automotive electronics systems demanding AEC-Q200 compliance

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm the presence of the internal fuse element and terminal configuration. Ensure that the selected variant matches the required current rating and voltage specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when simultaneous signal filtering and circuit protection are required within a single compact footprint. The C0G dielectric ensures minimal capacitance drift, making it suitable for precision timing or coupling applications where stability is critical. Confirm that the 50 mA fuse rating aligns with the maximum allowable current for the protected line.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines MLCC filtering characteristics with fuse functionality. These components are engineered for high-reliability environments, offering superior noise attenuation compared to standard capacitors while providing essential overcurrent protection in space-constrained designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative feed-through capacitors by matching the 1206 footprint, 100V rating, 0.033 µF capacitance, and 50 mA fuse current specifications.
