1812Y0500682MJTE03

Overview

The Knowles Syfer 1812Y0500682MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in the FlexiCap series. It features an X7R dielectric with a capacitance of 6.8 nF and a tolerance of ±20%. The component has a DC voltage rating of 50 V and operates within a temperature range of -55°C to +125°C. It utilizes a 1812 (4532 metric) package size with flexible nickel barrier terminations designed for board flex sensitivity.

Feature Summary

• Integrates X2Y architecture for simultaneous common-mode and differential-mode noise suppression
• Features flexible nickel barrier terminations to enhance reliability under mechanical stress
• Utilizes X7R dielectric material for stable capacitance performance across operating temperatures

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Board-flex sensitive circuit designs
• High-density PCB layouts requiring combined filtering and decoupling

Procurement Notes

Verify the specific suffix JE03 against official datasheets to confirm termination plating and packaging details. Ensure design compatibility with X2Y topology requirements rather than standard MLCC placement. Confirm RoHS and REACH status through manufacturer documentation prior to integration.

Selection Notes

Select this component when space constraints necessitate combining filtering and decoupling functions into a single footprint. The flexible terminations are critical for applications subject to mechanical strain or board warping. Verify that the X7R dielectric characteristics align with the required stability for the specific signal path.

Part Context

This part belongs to the Knowles Syfer FlexiCap family, which specializes in robust MLCCs for demanding environments. The 1812Y prefix indicates the 1812 case size and Y-series characteristics. The product line targets automotive and industrial sectors where mechanical durability and electromagnetic interference mitigation are primary design drivers.

Replacement Considerations

Direct substitutes must match the X2Y topology and 1812 package dimensions. Standard MLCCs cannot replace this component as they lack the integrated four-terminal noise suppression capability. Verify equivalent voltage ratings and capacitance values if considering alternative manufacturers.
