1812J5000223MXTE03

Overview

The Knowles Syfer 1812J5000223MXTE03 is a feed-through multilayer ceramic capacitor designed for surface mount applications. It features an X7R dielectric with a capacitance of 0.022 µF and a DC voltage rating of 500 VDC. The component operates within a temperature range of -55°C to +125°C. It utilizes a 1812 (4532 metric) package size with a three-pad configuration, integrating internal filtering capabilities directly into the passive component structure.

Feature Summary

• Integrates feed-through filtering functionality within a standard surface-mount footprint
• Utilizes X7R dielectric material for stable capacitance across operating temperatures
• Features a three-pad terminal configuration for direct PCB integration

Applications

• High-frequency noise suppression in electronic circuits
• Power line filtering for sensitive signal paths
• EMI reduction in compact surface-mount designs

Procurement Notes

Verify the specific suffix MXTE03 against official manufacturer documentation to confirm the three-pad feed-through variant. Standard MLCCs share similar part numbers but lack the integrated filtering structure. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to ensure supply chain compatibility.

Selection Notes

Select this component when space-constrained designs require both decoupling and filtering functions. The 1812 package allows for higher current handling compared to smaller footprints. Ensure the circuit layout accommodates the three-pad geometry rather than standard two-terminal patterns. Validate that the 500V rating meets the system's peak voltage requirements.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, which combines passive capacitance with electromagnetic interference suppression. Unlike traditional capacitors, these devices are engineered to attenuate noise while maintaining signal integrity. The 1812J series specifically targets high-reliability applications requiring robust performance in harsh thermal environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify exact dimensional tolerances and terminal configurations before considering alternative manufacturers.
