1812J5000472MXTE03

Overview

The Knowles Syfer 1812J5000472MXTE03 is a feed-through capacitor designed for surface-mount technology. It features a capacitance of 4700 pF with a DC voltage rating of 500 V. The component utilizes an X7R dielectric material and maintains a tolerance of ±20%. Housed in an 1812 (4532 metric) package, it supports a maximum current of 50 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates feed-through architecture for effective electromagnetic interference suppression
• Supports high continuous current handling up to 50 mA
• Utilizes X7R ceramic dielectric for stable performance across wide temperature ranges

Applications

• Electromagnetic interference filtering in high-current power lines
• Signal conditioning in sensitive electronic circuits requiring noise reduction
• Power supply input stages for voltage stabilization and ripple attenuation

Procurement Notes

Verify the specific suffix E03 against official datasheets to confirm pad configuration and pinout details. Ensure compatibility with existing PCB footprints, as feed-through capacitors require distinct mounting patterns compared to standard MLCCs. Confirm current ratings align with circuit requirements before integration.

Selection Notes

Select this component when both high-frequency noise suppression and significant current carrying capacity are required simultaneously. The feed-through design offers superior isolation compared to parallel-connected discrete components. Evaluate thermal management needs, as current flow generates heat within the internal structure during operation.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines filtering capabilities with structural robustness. Unlike standard multilayer ceramic capacitors, these devices integrate the conductive path directly through the dielectric body, optimizing space and enhancing shielding effectiveness in compact designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify mechanical footprint compatibility and electrical specifications carefully when considering alternative manufacturers or generic equivalents.
