1812Y5000153MJTE03

Overview

The Knowles Syfer 1812Y5000153MJTE03 is a feed-through multilayer ceramic capacitor in an 1812 (4532 metric) package. It features a capacitance of 0.015 µF with a DC voltage rating of 500V and a tolerance of ±20%. The component utilizes X7R dielectric material and includes a built-in 50 mA fuse element for overcurrent protection. It operates within a temperature range of -55°C to +125°C and employs flexible terminals to enhance board flex sensitivity.

Feature Summary

• Integrated 50 mA fuse element for circuit protection
• Flexible terminal construction for board flex resilience
• Feed-through architecture for compact EMI filtering

Applications

• High-density PCB layouts requiring integrated filtering and protection
• Automotive electronics systems
• Board-flex sensitive applications

Procurement Notes

Verify the specific suffix 'E03' against official datasheets to confirm the feed-through configuration and fuse rating. Ensure the selected variant matches the required 50 mA interruption capability and 1812 footprint dimensions for your design.

Selection Notes

Select this component when space constraints necessitate combining decoupling, filtering, and fusing functions into a single surface-mount device. The flexible terminations are critical for maintaining reliability in environments subject to mechanical stress or PCB warping during assembly.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability capacitors with soft terminations. The 1812Y series designation indicates the 1812 case size and Y-series product line characteristics, distinguishing it from standard MLCCs by its enhanced mechanical robustness.

Replacement Considerations

Direct substitutes must match the 1812 footprint, 500V rating, 0.015 µF capacitance, and specifically the 50 mA fuse characteristic. Generic MLCCs lack the integrated fuse and may not provide equivalent protection.
