1812J2000153MJTE03

Overview

The Knowles Syfer 1812J2000153MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-voltage applications. It features an X7R dielectric material providing stable capacitance characteristics across a wide temperature range from -55°C to +125°C. The component offers a nominal capacitance of 15 nF with a tolerance of ±20% and a DC voltage rating of 200 V. Housed in a standard 1812 (4532 metric) package, it incorporates a nickel barrier electrode structure with 100% tin terminations to enhance solderability and reliability.

Feature Summary

• Incorporates a nickel barrier internal electrode structure combined with 100% tin external terminations for improved soldering performance and corrosion resistance.
• Utilizes X7R dielectric technology to maintain consistent electrical properties under varying thermal conditions within the specified operating range.
• Constructed as an X2Y capacitor configuration, offering integrated common-mode noise suppression capabilities alongside standard capacitance functions.

Applications

• High-voltage circuit protection and filtering in industrial power supplies
• Noise suppression in automotive electronic control units requiring robust thermal stability
• General-purpose decoupling in sensitive analog and digital mixed-signal circuits

Procurement Notes

Verify the specific termination finish and electrode structure against the official datasheet to ensure compatibility with your assembly process. Confirm that the X2Y topology aligns with your schematic requirements, as this component provides specific filtering characteristics distinct from standard MLCCs. Always check for the latest RoHS compliance status and any recent product change notices issued by Knowles Syfer before finalizing procurement.

Selection Notes

Select this component when a compact 1812 footprint is required for 200V applications needing moderate capacitance stability. The X7R dielectric is suitable for general-purpose uses where tight capacitance tolerance is not critical. Consider the nickel barrier construction if lead-free soldering processes are mandated. Ensure the board layout accommodates the specific pad design required for X2Y configurations to realize the intended noise suppression benefits.

Part Context

This part belongs to the Knowles Syfer 1812J series of high-reliability MLCCs. The 'J' designation typically indicates the 1812 case size and voltage class within their catalog. The suffix 'MJTE03' specifies the particular termination, electrode, and packaging details. This series is engineered for demanding environments where standard capacitors might fail due to voltage stress or thermal cycling.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 200V rating, 15nF capacitance, and X7R dielectric. Verify that alternative components support the X2Y pin configuration if noise filtering is essential. Cross-reference termination materials to ensure solderability compatibility with existing manufacturing equipment.
