Overview
The Knowles Syfer 1812Y1000823MJTE03 is a feed-through ceramic capacitor with a capacitance of 0.082 µF and a voltage rating of 100V. It utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. The component features a 1812 (4532 metric) package size and includes a 50 mA current rating. Designed for surface mount applications, it offers high reliability in demanding environments.
Feature Summary
- Integrated feed-through design combining filtering and decoupling functions
- High current handling capability suitable for power line protection
- Flexible terminal construction to withstand board flex stress
Applications
- Automotive electronics requiring AEC-Q200 compliance
- Board-flex sensitive circuit assemblies
- Power supply input filtering stages
Procurement Notes
Verify the specific suffix MJTE03 against official datasheets to confirm the feed-through configuration and current rating. Standard MLCC part numbers may differ significantly from this specialized variant. Ensure compatibility with PCB pad layouts designed for three-terminal feed-through structures rather than standard two-terminal capacitors.
Selection Notes
Select this component when both signal integrity filtering and mechanical robustness are required. The flexible terminals address reliability issues in vibration-prone or flex-stressed applications. Confirm that the 50 mA current rating meets the specific circuit requirements before finalizing the design.
Part Context
This component belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors with soft terminals. The series is engineered to improve solder joint reliability in applications subject to mechanical stress. The 1812Y prefix indicates the specific family within the broader product portfolio.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific feed-through variant are not available in the provided documentation. Generic MLCC replacements will not provide the integrated feed-through functionality or the specified current rating.
