1812J5000822MJTE03

Overview

The Knowles Syfer 1812J5000822MJTE03 is a surface-mount multilayer ceramic capacitor (MLCC) in the 1812 (4532 metric) package. It features an X7R dielectric with a capacitance of 8200 pF and a voltage rating of 500 VDC. The component offers a tolerance of ±20% and operates within a temperature range of -55°C to +125°C. It utilizes a nickel barrier electrode structure with 100% tin terminations, designed as an EMI filter.

Feature Summary

• Integrated X2Y three-terminal architecture for enhanced electromagnetic interference suppression
• Nickel barrier termination system providing robust solderability and reliability
• Class 1/2 hybrid construction optimized for high-frequency filtering applications

Applications

• High-density electronic assemblies requiring compact EMI filtering
• Automotive electronics systems subject to strict noise immunity standards
• Industrial control circuits demanding reliable signal integrity protection

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct terminal material and capacitance tolerance. Confirm that the X2Y topology aligns with circuit layout requirements. Check for RoHS compliance status and lead-free certification before procurement. Ensure storage conditions maintain component integrity prior to assembly.

Selection Notes

Select this component when space constraints necessitate a three-terminal filter within a standard 1812 footprint. The X7R dielectric provides stable performance across varying temperatures. Consider the nickel barrier termination for improved mechanical strength during reflow processes compared to standard silver electrodes.

Part Context

This part belongs to the Knowles Syfer EMI Filter series, specifically utilizing the X2Y technology. It integrates three terminals into a single monolithic structure to provide common-mode and differential-mode noise attenuation. The design replaces discrete filter components, reducing board space and parasitic inductance in high-speed digital circuits.
