1812J2000821MCTE03

Overview

The Knowles Syfer 1812J2000821MCTE03 is an X2Y capacitor featuring a multilayer ceramic construction in a 1812 (4532 metric) surface-mount package. It provides a capacitance of 820 pF with a ±20% tolerance and a rated DC voltage of 200V. The component utilizes C0G/NP0 dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. It employs nickel barrier and 100% tin terminations for reliable soldering.

Feature Summary

• X2Y architecture integrates three terminals into a single device to provide simultaneous common-mode and differential-mode noise suppression.
• C0G/NP0 dielectric ensures minimal capacitance variation over temperature and voltage changes for high-stability applications.

Applications

• High-speed data line filtering
• Power supply input/output decoupling
• EMI suppression in sensitive electronic circuits

Procurement Notes

Verify the specific suffix MCTE03 against official datasheets to confirm termination plating and packaging details. Ensure compatibility with automated placement equipment regarding the 1812 footprint. Confirm RoHS compliance status through current manufacturer documentation before integration.

Selection Notes

Select this component when space-constrained designs require combined common-mode and differential-mode filtering capabilities. The X2Y topology reduces board area compared to discrete filter networks. Verify that the 200V rating and 820pF value align with the target circuit's signal integrity requirements.

Part Context

This part belongs to the Knowles Syfer X2Y family, which combines three capacitors in one package. The 1812J series denotes the 1812 case size within this lineup. These components are designed for high-frequency noise reduction where traditional two-terminal capacitors may be insufficient due to parasitic inductance.
