1812J2000124MXTE03

Overview

The Knowles Syfer 1812J2000124MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) from the XT series. It features an X7R dielectric with a capacitance of 0.12 µF and a DC voltage rating of 200 VDC. The component utilizes a standard 1812 (4532 metric) package size with ±20% tolerance. It operates within a temperature range of -55°C to +125°C and is supplied in reel packaging.

Feature Summary

• Utilizes X7R dielectric material for stable capacitance characteristics across varying temperatures.
• Designed for surface-mount technology (SMD/SMT) integration into printed circuit boards.
• Constructed in a compact 1812 case size to support high-density electronic assemblies.

Applications

• General-purpose multilayer ceramic capacitor circuits
• High-reliability electronic system decoupling
• Industrial control board filtering applications

Procurement Notes

Verify the specific suffix E03 against official manufacturer documentation to confirm exact packaging or marking variations, as distributor listings may not detail all suffix implications. Ensure the source document explicitly confirms this suffix does not alter electrical performance. Cross-reference the Mouser number 843-1812J2000124MXTE03 with the manufacturer's current catalog to validate availability and compliance status before procurement.

Selection Notes

Select this component when a 200V DC rated MLCC with X7R stability is required in an 1812 footprint. The ±20% tolerance suits general applications where precise capacitance is less critical than cost and volume. Confirm that the operating environment remains within the specified -55°C to +125°C range to ensure reliable performance without derating requirements beyond standard guidelines.

Part Context

This part belongs to the Knowles Syfer XT series of general-type MLCCs. The series is characterized by standard termination types and robust construction suitable for industrial environments. The 1812J prefix indicates the 1812 case dimensions, while the J likely denotes the voltage class within the product line structure defined by the manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with any alternative components by matching the 1812 footprint, 200V rating, X7R dielectric, and 0.12µF capacitance values strictly.
