1812Y1000272MSTE03

Overview

The Knowles Syfer 1812Y1000272MSTE03 is a feed-through multilayer ceramic capacitor in an 1812 (4532 metric) surface-mount package. It features a capacitance of 2700 pF with a voltage rating of 100 VDC and a current rating of 50 mA. The component utilizes a C0G/NP0 dielectric for stable performance across temperatures ranging from -55°C to +125°C. It incorporates FlexiCap technology with a nickel barrier termination system, designed for high-reliability applications requiring effective electromagnetic interference suppression.

Feature Summary

• Integrates FlexiCap technology with a nickel barrier termination structure for enhanced mechanical stability and solder joint reliability.
• Functions as a three-terminal feed-through capacitor to provide superior high-frequency noise attenuation compared to standard two-terminal designs.
• Utilizes C0G/NP0 dielectric material to maintain consistent capacitance values under varying temperature conditions.

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive electronic circuits
• Electromagnetic interference suppression in automotive electronics

Procurement Notes

Verify the specific suffix MSTE03 against official datasheets to confirm the inclusion of FlexiCap termination and nickel barrier specifications. Ensure compatibility with automated pick-and-place equipment due to the 1812 package dimensions. Confirm that the 50 mA current rating meets the operational requirements of the target circuit design before finalizing procurement.

Selection Notes

Select this component when superior high-frequency noise reduction is required over standard MLCCs. The three-terminal feed-through architecture offers lower parasitic inductance. Consider the 1812 footprint constraints and verify that the 100 VDC rating aligns with the maximum operating voltage of the application environment.

Part Context

This part belongs to the Knowles Syfer X2Y and feed-through capacitor series, which are engineered for robust EMI/RFI suppression. These components are distinct from general-purpose capacitors by their internal electrode configuration that creates multiple grounding paths, significantly improving filtering efficiency in compact form factors.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameters if considering alternative manufacturers' feed-through capacitors.
