1812J0500684MXTE07

Overview

The Knowles Syfer 1812J0500684MXTE07 is a multilayer ceramic capacitor (MLCC) in the XT series, designed for surface-mount technology. It features an X7R dielectric material and offers a capacitance of 0.68 µF with a tolerance of ±20%. The component is rated for a DC voltage of 50 V and operates within a temperature range of -55°C to +125°C. Housed in a standard 1812 (4532 metric) package, it utilizes standard SMD/SMT terminations. This part is specifically engineered as a feed-through capacitor, providing integrated electromagnetic interference filtering capabilities alongside its energy storage function.

Feature Summary

• Integrates feed-through architecture to provide simultaneous signal filtering and power decoupling within a single compact component.
• Utilizes X7R ceramic dielectric to maintain stable capacitance performance across a wide industrial operating temperature range.
• Features a robust 1812 surface-mount footprint designed for automated assembly and high-density circuit board layouts.

Applications

• High-frequency noise suppression in sensitive analog and digital signal lines
• Power supply input and output filtering for low-voltage electronic modules
• Electromagnetic interference mitigation in compact consumer electronics

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct termination and packaging specifications. Confirm RoHS compliance status and environmental declarations prior to integration. Cross-reference the manufacturer's latest production change notices to validate current manufacturing parameters and availability constraints.

Selection Notes

Select this component when space-constrained designs require combined filtering and decoupling functions. Ensure the 50V rating exceeds the maximum circuit voltage including transients. Verify that the 1812 package dimensions align with the PCB footprint and that the X7R characteristics meet the thermal stability requirements of the target application environment.

Part Context

This component belongs to the Knowles Syfer XT series, which specializes in high-reliability ceramic capacitors. The XT line integrates passive filtering directly into the capacitor structure, reducing the component count and board area required for EMI suppression compared to traditional discrete filter networks.

Replacement Considerations

Direct substitutes must match the 1812 form factor, 50V rating, 0.68µF value, and feed-through functionality. Verify terminal compatibility and thermal ratings before substitution.
