1812J0500105MXTE07

Overview

The Knowles Syfer 1812J0500105MXTE07 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount technology. It features a capacitance of 1 µF with a ±20% tolerance, utilizing X7R dielectric material. The component is rated for a DC voltage of 50 VDC and operates within a temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it incorporates the FlexiCap construction with a nickel barrier to enhance mechanical robustness against cracking. This device belongs to the XT series, engineered for demanding electronic applications requiring stable performance under thermal and mechanical stress.

Feature Summary

• FlexiCap construction with nickel barrier enhances resistance to mechanical shock and thermal cycling-induced cracking.
• X7R dielectric provides stable capacitance characteristics across a wide operating temperature range.
• High-reliability design suitable for rigorous industrial and automotive environments.

Applications

• Automotive electronics systems
• Industrial control equipment
• General-purpose high-reliability circuits

Procurement Notes

Verify the complete part number including the suffix MXTE07 to ensure correct packaging and specific FlexiCap/Nickel Barrier configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet specifications for mechanical dimensions and soldering profiles to guarantee compatibility with assembly processes.

Selection Notes

Select this component when high mechanical reliability is required alongside standard X7R capacitance stability. The 1812 package offers a balance between capacitance density and physical footprint. Ensure the 50V rating meets circuit requirements. Consider the XT series designation for verified high-reliability standards compared to general-type MLCCs.
