1812Y1000332MJTE03

Overview

The Knowles Syfer 1812Y1000332MJTE03 is a three-terminal feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 3300 pF with a voltage rating of 100 VDC and a tolerance of ±20%. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Housed in a compact 1812 (4532 metric) surface-mount package, it includes a 50 mA current rating. This device integrates EMI filtering directly into the circuit layout, offering a robust solution for sensitive electronic applications requiring effective signal integrity management.

Feature Summary

• Three-terminal architecture provides enhanced electromagnetic interference filtering capabilities
• Integrated feed-through design minimizes parasitic inductance for superior high-frequency performance
• X7R dielectric ensures stable capacitance characteristics across wide temperature variations
• Surface-mount construction facilitates automated assembly and space-constrained board layouts

Applications

• High-speed digital signal line filtering
• Power supply input/output noise suppression
• RF circuit grounding and decoupling
• Automotive electronics requiring AEC-Q200 compliance

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and termination material specifications. Ensure that the selected variant matches the required current rating and thermal endurance for the target application environment. Cross-reference part numbers with authorized distributors to confirm authenticity and traceability before procurement.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete components. Evaluate the trade-off between the three-terminal footprint size and the improved filtering performance compared to standard two-terminal capacitors. Confirm that the 100V DC rating exceeds the maximum peak voltage in the circuit to ensure long-term reliability under operational stress conditions.

Part Context

This component belongs to the Knowles Syfer FlexiCap™ series, which specializes in flexible termination technologies for board-flex sensitive applications. As a feed-through capacitor, it differs from standard MLCCs by providing a direct ground path through the center terminal, effectively shunting high-frequency noise while passing desired signals or power with minimal attenuation.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 3300 pF capacitance, 100V rating, and three-terminal feed-through structure. Verify compatibility of termination materials and current ratings. No specific equivalent part numbers are publicly confirmed in the provided source data.
