1812J0500124MJTE03

Overview

The Knowles Syfer 1812J0500124MJTE03 is a feed-through capacitor with a capacitance of 0.12 µF and a voltage rating of 50 VDC. It utilizes X7R dielectric material and features a 1812 (4532 metric) surface-mount package. The component supports a maximum current of 50 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated feed-through design for combined filtering and decoupling
• High-current capability supporting up to 50 mA signal passage
• X7R dielectric stability across extended industrial temperature ranges

Applications

• High-frequency signal line filtering in communication equipment
• Power supply input/output decoupling in sensitive analog circuits
• EMI suppression in compact high-density PCB layouts

Procurement Notes

Verify the specific suffix 'E03' against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure compatibility with 50 mA continuous current requirements in the target circuit design before procurement.

Selection Notes

Select this component when both signal integrity filtering and power delivery are required on the same trace. The 1812 footprint offers a balance between current handling capacity and board space efficiency compared to smaller packages.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, designed for applications requiring superior EMI/RFI attenuation. Unlike standard MLCCs, these components integrate a conductive path through the dielectric structure, enabling simultaneous signal transmission and noise suppression.
