1812Y2000153MJTE03

Overview

The Knowles Syfer 1812Y2000153MJTE03 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.015 µF with a voltage rating of 200 VDC and a maximum current handling capacity of 50 mA. The component utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it integrates a three-terminal structure to provide effective electromagnetic interference filtering while maintaining low parasitic inductance.

Feature Summary

• Integrates a three-terminal feed-through architecture for enhanced high-frequency noise attenuation
• Features a robust 50 mA current carrying capability suitable for power line filtering applications
• Utilizes X7R ceramic dielectric to maintain capacitance stability under varying thermal conditions

Applications

• Electromagnetic interference filtering in automotive electronic control units
• Noise suppression on DC power input lines in industrial equipment
• Signal integrity protection in high-speed digital circuitry requiring common-mode noise reduction

Procurement Notes

Verify the specific terminal configuration and pinout against the official datasheet before integration, as feed-through capacitors require distinct pad layouts compared to standard MLCCs. Confirm that the 50 mA current rating aligns with the operational load of the target circuit to prevent thermal degradation. Ensure the PCB footprint matches the 1812 package dimensions precisely to guarantee proper solder joint formation and mechanical reliability during assembly processes.

Selection Notes

Select this component when both capacitance value and current handling are critical constraints. The 200V rating provides sufficient margin for many low-voltage DC systems. Consider the physical size relative to available board space, as the three-terminal design occupies more area than equivalent two-terminal capacitors. Evaluate the impedance characteristics at the target frequency to ensure adequate attenuation for the specific noise profile encountered in the application environment.

Part Context

This part belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability ceramic capacitors. The 'J' suffix typically denotes a specific termination or barrier layer technology, often associated with nickel barriers for improved solderability and corrosion resistance. This series is engineered for demanding environments where standard MLCCs may fail due to mechanical stress or electrical overstress.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Any replacement must match the 0.015 µF capacitance, 200 VDC rating, 50 mA current limit, and 1812 package dimensions. Verify that alternative feed-through capacitors offer comparable impedance characteristics and thermal stability.
