1812J1000223MJTE03

Overview

The Knowles Syfer 1812J1000223MJTE03 is a multilayer ceramic capacitor (MLCC) designed for high-reliability applications. It features a 22 nF capacitance value with a tolerance of ±20% (M code). The component operates at a rated voltage of 100 V DC and utilizes a Class 2 X7R dielectric material, ensuring stable performance across a wide temperature range from -55°C to +125°C. Housed in an 1812 (4532 Metric) surface-mount package, it offers low equivalent series resistance (ESR) and high ripple current capability. The termination structure consists of silver/palladium/silver plating, suitable for standard reflow soldering processes without requiring special handling procedures.

Feature Summary

• Utilizes X7R dielectric material for stable capacitance over varying temperatures
• Designed for high reliability in demanding electronic environments
• Features robust termination structure compatible with standard surface-mount assembly

Applications

• General-purpose decoupling in industrial control systems
• Filtering applications in automotive electronics
• Power supply bypassing in communication equipment

Procurement Notes

Verify the complete part number including suffixes against official Knowles Syfer documentation to ensure correct dielectric type, voltage rating, and termination finish. Confirm that the specific batch meets required quality standards for your application environment. Cross-reference manufacturer datasheets for any recent updates regarding compliance or packaging changes before finalizing procurement orders.

Selection Notes

Select this component when a 22 nF capacitance with 100 V rating is required in an 1812 footprint. Ensure the operating temperature range aligns with the X7R characteristics. Consider physical size constraints and mounting orientation during PCB layout design. Verify compatibility with available soldering profiles and thermal management strategies for the target assembly process.

Part Context

This component belongs to the Knowles Syfer high-reliability MLCC family, engineered for sectors requiring consistent performance under stress. The 1812J series specifically targets applications needing robust capacitance values in compact surface-mount formats. These capacitors are widely used in industries where failure rates must be minimized through rigorous manufacturing controls and material stability.

Replacement Considerations

Consult official substitution guides for direct equivalents. Ensure replacement parts match the 1812 package dimensions, 100 V rating, 22 nF capacitance, and X7R dielectric class. Verify terminal compatibility and lead-free status if required by environmental regulations.
