1812Y2000103MJTE03

Overview

The Knowles Syfer 1812Y2000103MJTE03 is a surface-mount X2Y capacitor with a capacitance of 10 nF and a voltage rating of 200 VDC. It features a 1812 (4532 metric) package size and utilizes an X7R dielectric material. The component offers a tolerance of ±20% and includes a 50 mA current rating specification. It employs a nickel barrier termination structure with 100% tin plating, designed for high-reliability applications requiring compact footprint and enhanced noise suppression capabilities.

Feature Summary

• Integrates three-terminal X2Y architecture to provide simultaneous common-mode and differential-mode noise filtering within a single compact device.
• Utilizes flexible soft termination technology to absorb mechanical stress from board flexing, thereby reducing the risk of crack formation during assembly or operation.
• Features a nickel barrier electrode structure combined with 100% tin terminations to ensure reliable solderability and long-term corrosion resistance.

Applications

• Noise suppression in high-speed digital signal lines
• Power supply decoupling for sensitive integrated circuits
• EMI filtering in automotive electronic control units

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact termination and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the production line. Ensure that the selected reel quantity aligns with manufacturing throughput needs.

Selection Notes

Select this component when space constraints require a multi-terminal filter solution. The X2Y topology allows for reduced board area compared to discrete capacitor networks. Evaluate the mechanical flexibility requirements of the target PCB to leverage the soft termination benefits effectively.
