1812Y0500564METE03

Overview

The Knowles Syfer 1812Y0500564METE03 is a feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.56 µF with a rated voltage of 50V and a maximum current rating of 50 mA. The component utilizes a C0G/NP0 dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in an 1812 (4532 metric) surface-mount package, it offers low impedance characteristics suitable for EMI filtering applications.

Feature Summary

• Integrated feed-through architecture for effective electromagnetic interference suppression
• C0G/NP0 dielectric material provides stable capacitance over varying temperatures
• Flexible terminal construction reduces mechanical stress on the printed circuit board
• AEC-Q200 qualified for automotive reliability standards

Applications

• Automotive electronic systems requiring robust EMI filtering
• Board-flex sensitive circuits needing stress-relief termination
• High-frequency noise suppression in power supply lines
• Consumer electronics demanding compact filter solutions

Procurement Notes

Verify the specific suffix METE03 against official datasheets to confirm the feed-through configuration and terminal type. Ensure compatibility with PCB footprint dimensions for the 1812 package. Confirm RoHS compliance status if required by project specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when integrated feed-through filtering is preferred over discrete capacitors to save space. The 50V rating and 50mA current limit define the operational boundaries. Consider the C0G dielectric for applications requiring minimal capacitance drift. Evaluate the 1812 package size against available board real estate constraints.
