1812Y2000472MXTE03

Overview

The Knowles Syfer 1812Y2000472MXTE03 is a feed-through multilayer ceramic capacitor designed for surface-mount technology. It features a capacitance of 4700 pF with a voltage rating of 200 VDC and a maximum current handling capacity of 50 mA. The component utilizes an X7R dielectric material housed in a standard 1812 (4532 metric) package footprint. This specific part number denotes the FlexiCap variant, which incorporates flexible end terminations to enhance mechanical reliability under board flex conditions.

Feature Summary

• Integrated feed-through architecture providing internal grounding for superior electromagnetic interference suppression
• Flexible end termination design engineered to absorb mechanical stress and prevent cracking during PCB deformation
• X7R dielectric composition ensuring stable capacitance performance across a wide operational temperature range

Applications

• Automotive electronics requiring AEC-Q200 qualified components
• High-density circuit boards susceptible to mechanical flexing
• Signal lines requiring integrated filtering and grounding

Procurement Notes

Verify the complete ordering suffix against official manufacturer documentation to ensure correct termination style and tolerance specifications. Confirm that the selected variant matches the required current rating and package dimensions for your specific assembly process. Cross-reference the datasheet for any recent product change notices or environmental compliance updates prior to finalizing procurement orders.

Selection Notes

Select this component when both high-frequency noise attenuation and mechanical durability are critical design requirements. The feed-through structure offers lower parasitic inductance compared to standard MLCCs, making it suitable for sensitive signal paths. Ensure the application environment does not exceed the specified voltage and current limits defined in the electrical characteristics table.

Part Context

This component belongs to the Knowles Syfer 1812Y series, which specializes in high-reliability capacitors for demanding environments. The 'FlexiCap' designation indicates the presence of compliant end electrodes, distinguishing it from rigid-termination counterparts within the same family. These parts are widely utilized in industries where vibration resistance and signal integrity are paramount.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 4700 pF capacitance, 200 V rating, and specifically the FlexiCap flexible termination style. Verify that alternative feed-through capacitors maintain comparable current handling capabilities and electromagnetic interference suppression performance.
