1812J5000123MJTE03

Overview

The Knowles Syfer 1812J5000123MJTE03 is a feed-through capacitor designed for surface-mount technology. It features a capacitance of 0.012 µF and a DC voltage rating of 500 V. The component operates within a temperature range of -55°C to +125°C and includes an integrated current rating of 50 mA. Its physical dimensions conform to the 1812 (4532 metric) package outline, with a footprint requiring three pads for mounting.

Feature Summary

• Integrates feed-through functionality for combined filtering and conduction
• Supports continuous current flow up to 50 mA
• Designed for high-reliability surface-mount applications

Applications

• High-frequency signal filtering in RF circuits
• Power distribution networks requiring inline decoupling
• Electromagnetic interference suppression in compact modules

Procurement Notes

Verify the specific suffix MJTE03 against official manufacturer documentation to confirm pin configuration and termination specifications. Ensure compatibility with PCB pad layouts designed for three-terminal feed-through structures. Cross-reference datasheet revisions to validate performance parameters under operating conditions.

Selection Notes

Select this component when simultaneous signal filtering and power transmission are required in a single surface-mount device. Evaluate thermal management requirements given the 50 mA current handling capability. Confirm that the 1812 footprint aligns with available board space and assembly equipment constraints.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which combines ceramic dielectric properties with conductive center terminals. Unlike standard multilayer capacitors, these components allow current to pass through the body while providing shunt capacitance to ground. This architecture supports efficient noise reduction in space-constrained electronic assemblies.
