1812J1000204MXTE03

Overview

The Knowles Syfer 1812J1000204MXTE03 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 1812 (4532 metric) case size with a nominal capacitance of 0.2 µF and a DC voltage rating of 100 VDC. The component utilizes X7R dielectric material, providing stable performance across a wide operating temperature range from -55°C to +125°C. It offers a tolerance of ±20% and is terminated with standard SMD/SMT electrodes. The device is supplied in reel packaging, suitable for automated surface-mount assembly processes.

Feature Summary

• High reliability construction suitable for demanding electronic environments
• X7R dielectric ensures stable capacitance characteristics over varying temperatures
• Standard surface mount termination facilitates automated PCB assembly

Applications

• General purpose decoupling and bypassing in electronic circuits
• Signal conditioning and filtering in communication equipment
• Power supply stabilization in industrial control systems

Procurement Notes

Verify the specific manufacturing date code and lot traceability upon receipt to ensure compliance with project quality standards. Confirm that the reel packaging remains sealed and undamaged during transit to prevent moisture ingress or mechanical stress. Cross-reference the part number with the latest manufacturer datasheet to confirm current RoHS and REACH compliance status before final integration into production lines.

Selection Notes

Select this component when a 1812 footprint is required for 100V applications needing moderate capacitance stability. The X7R dielectric is appropriate for general-purpose uses where tight tolerance is not critical. Ensure the design allows for the physical dimensions of the 1812 package and accounts for the thermal expansion characteristics associated with this dielectric type during soldering and operation.

Part Context

This part belongs to the Knowles Syfer portfolio of high-reliability ceramic capacitors. The 'J' suffix typically denotes the 1812 case size, while '1000' indicates the 100V rating. The '204' code specifies the 0.2 µF capacitance value using EIA standard coding. The 'MXTE03' suffix identifies the specific termination and packaging configuration, distinguishing it from other variants within the same electrical specification family.

Replacement Considerations

Direct substitutes must match the 1812 case size, 100V rating, 0.2 µF capacitance, and X7R dielectric. Verify that alternative manufacturers offer compatible termination materials and equivalent thermal stability ratings to ensure seamless integration without redesigning the PCB layout or circuit parameters.
