1812Y0500155MXTE07

Overview

The Knowles Syfer 1812Y0500155MXTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed as an EMI filter. It features a capacitance of 1.5 µF with a ±20% tolerance, utilizing X7R dielectric material. The component has a DC voltage rating of 50 VDC and operates within a temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) surface-mount package, it incorporates FlexiCap technology for flexible terminations and a nickel barrier layer to enhance reliability against termination cracking.

Feature Summary

• Three-terminal architecture functions as an integrated EMI filter for noise suppression
• FlexiCap flexible terminations reduce mechanical stress on the component body
• Nickel barrier layer provides enhanced protection against termination cracking

Applications

• High-frequency noise filtering in sensitive electronic circuits
• Power supply input stages requiring EMI suppression
• Signal line protection in automotive or industrial control systems

Procurement Notes

Verify the specific suffix MXTE07 to confirm the inclusion of the nickel barrier and three-terminal configuration, as standard two-terminal variants exist within the same series. Ensure compatibility with automated pick-and-place equipment due to the 1812 footprint dimensions. Confirm RoHS compliance status through the official datasheet before integration into regulated assemblies.

Selection Notes

Select this component when simultaneous high capacitance and EMI filtering are required in a single surface-mount package. The three-terminal design offers superior high-frequency performance compared to standard two-terminal capacitors. Consider the FlexiCap feature if the application involves significant PCB flexing or thermal cycling that might compromise rigid terminations.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, which specializes in high-reliability MLCCs. The 1812Y prefix indicates the 1812 case size and 50V voltage class. The Y0500155 code specifies the 1.5 µF capacitance value. The MXTE07 suffix denotes the specific packaging and terminal construction details.

Replacement Considerations

Direct substitutes must match the 1.5 µF capacitance, 50 VDC rating, X7R dielectric, and three-terminal EMI filter topology. Verify that alternative parts also include nickel barrier layers and flexible terminations if mechanical reliability is critical. Standard two-terminal 1812 capacitors are not electrically equivalent replacements.
