1812J5000683MXTE03

Overview

The Knowles Syfer 1812J5000683MXTE03 is a feedthrough multilayer ceramic capacitor with a capacitance of 0.068 µF and a DC voltage rating of 500 VDC. It utilizes X7R dielectric material and offers a tolerance of ±20%. Designed for the 1812 (4532 metric) surface-mount package, it features flexible end terminations to enhance mechanical reliability. The component operates within a temperature range of -55°C to +125°C and supports a maximum current rating of 50 mA.

Feature Summary

• Integrated feedthrough architecture combining filtering and mounting functions
• Flexible end terminations designed to absorb mechanical stress
• High-voltage capability suitable for demanding power applications

Applications

• Power supply input filtering
• EMI suppression in high-voltage circuits
• Industrial control system protection

Procurement Notes

Verify the specific E03 suffix against official documentation to confirm environmental compliance or special marking requirements. Ensure the selected distributor provides traceable data sheets matching the manufacturer's latest revision. Confirm that the flexible termination specifications align with your board layout stress analysis before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a combined feedthrough and filter solution in a standard 1812 footprint. The X7R dielectric ensures stable performance across the specified industrial temperature range. Verify that the 50 mA current rating meets the circuit requirements and that the 500 VDC rating provides adequate margin for transient voltages.

Part Context

This part belongs to the Knowles Syfer general type MLCC series, specifically engineered as a feedthrough capacitor. It integrates the filtering function directly into the mounting structure, reducing component count and assembly complexity compared to discrete filter designs.

Replacement Considerations

Cross-reference with other 1812 feedthrough capacitors from Knowles Syfer offering identical 500V ratings and 0.068 µF capacitance. Verify that any substitute maintains the same flexible termination characteristics and thermal operating limits.
