1812J0250155MXTE07

Overview

The Knowles Syfer 1812J0250155MXTE07 is a three-terminal feed-through multilayer ceramic capacitor designed for surface mount applications. It features an X7R dielectric with a capacitance of 1.5 µF and a voltage rating of 25 VDC. The component utilizes a nickel barrier termination system with 100% tin plating, housed in a standard 1812 (4532 metric) package. This configuration provides high capacitance density within a compact footprint suitable for dense circuit board layouts.

Feature Summary

• Three-terminal feed-through architecture enables effective electromagnetic interference filtering by providing low-inductance signal paths.
• X7R dielectric material ensures stable capacitance performance across a wide operating temperature range from -55°C to +125°C.
• Nickel barrier termination structure with 100% tin plating offers robust solderability and resistance to corrosion during assembly.

Applications

• High-density power supply input/output filtering
• Digital logic circuit decoupling and noise suppression
• General-purpose EMI suppression in compact electronic modules

Procurement Notes

Verify the specific termination finish and dielectric characteristics against the official datasheet before integration. Confirm that the three-terminal physical dimensions align with the target PCB footprint. Ensure the selected component meets all required environmental and reliability standards for the intended operational environment.

Selection Notes

Select this component when high capacitance values are required in a small surface-mount form factor. The three-terminal design is preferred over standard two-terminal capacitors for superior high-frequency noise attenuation. Consider the X7R temperature coefficient when designing circuits subject to significant thermal variations.

Part Context

This part belongs to the Knowles Syfer MLCC family, specifically engineered for high-reliability applications. The 1812J series designation indicates a standard size with specific voltage and capacitance ratings. These components are widely used in industrial and consumer electronics where space constraints and electrical performance are critical.

Replacement Considerations

Direct substitutes must match the 1.5 µF capacitance, 25 VDC rating, X7R dielectric, and three-terminal feed-through topology. Verify that alternative parts maintain identical nickel barrier termination specifications and 1812 package dimensions to ensure mechanical compatibility.
