1812Y1000823METE03

Overview

The Knowles Syfer 1812Y1000823METE03 is a feed-through ceramic capacitor designed for high-frequency noise suppression. It features a capacitance of 0.082 µF with a rated DC voltage of 100V and a maximum current rating of 50 mA. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Housed in a compact 1812 (4532 metric) surface-mount package, it incorporates flexible terminals to enhance board flex reliability. This part is specifically engineered for applications requiring robust EMI filtering in space-constrained environments.

Feature Summary

• Integrated feed-through architecture provides effective electromagnetic interference suppression within a single surface-mount component.
• Flexible terminal construction mitigates mechanical stress during board flexing, improving durability in sensitive assemblies.
• X7R dielectric material ensures stable capacitance performance over a wide industrial temperature range.

Applications

• High-frequency noise filtering in automotive electronic control units
• EMI suppression in board-flex sensitive consumer electronics
• Power line decoupling in compact mobile devices

Procurement Notes

Verify the complete part number including the E03 suffix, as it denotes specific packaging or variant details distinct from standard reel configurations. Confirm that the design accommodates the three-pad footprint required for feed-through mounting. Ensure the application circuit does not exceed the 50 mA current rating to prevent component degradation. Cross-reference the latest datasheet for any updates on RoHS compliance status and recommended soldering profiles.

Selection Notes

Select this component when integrated EMI filtering and board flex resistance are critical requirements. The feed-through design reduces component count compared to discrete filter networks. Consider the 1812 footprint constraints and the need for three connection pads on the PCB layout. Evaluate if the 100V rating and 0.082 µF capacitance align with the target circuit's noise spectrum and voltage levels.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors with flexible terminations. The series targets applications susceptible to mechanical stress, such as automotive and portable electronics. The 1812Y base designation indicates the standard 1812 case size, while the METE03 suffix identifies the specific feed-through configuration and packaging type within the product family.

Replacement Considerations

Direct substitutes must match the feed-through topology and 1812 footprint. Standard MLCCs lack the internal conductive path and may require additional components for equivalent filtering. Verify compatibility with existing PCB footprints, as feed-through parts typically utilize three pads rather than two.
