1812Y1000683MJTE03

Overview

The Knowles Syfer 1812Y1000683MJTE03 is a feed-through capacitor with a capacitance of 0.068 µF and a rated voltage of 100 V. It operates within a temperature range of -55°C to +125°C. The component utilizes an X7R dielectric material and features a 1812 (4532 metric) surface-mount package. It includes a 50 mA current rating and incorporates soft terminal technology for enhanced mechanical reliability.

Feature Summary

• Feed-through architecture providing integrated filtering capabilities
• Soft terminal design engineered for board flex sensitivity
• High current handling capability of 50 mA

Applications

• Automotive electronics requiring AEC-Q200 compliance
• Applications sensitive to board flex stress
• High-current signal filtering circuits

Procurement Notes

Verify the specific suffix JTE03 against official documentation to confirm the feed-through configuration and current rating, as standard MLCC variants may differ. Confirm RoHS3 compliance and moisture sensitivity level prior to integration. Ensure the 50 mA rating aligns with circuit requirements.

Selection Notes

Select this component when both high-frequency filtering and mechanical durability are required. The feed-through structure offers superior noise suppression compared to standard capacitors. The soft terminals mitigate cracking risks in flexible PCB environments. Verify that the 100V rating and 0.068 µF value meet the specific electrical needs of the application.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, which specializes in robust ceramic capacitors for demanding environments. The 1812Y series typically denotes high-voltage or specialized performance characteristics within the manufacturer's portfolio. This specific model integrates feed-through functionality into the standard 1812 footprint.

Replacement Considerations

Standard MLCCs lack the feed-through structure and 50 mA current rating. Direct substitutes must match the feed-through topology and soft terminal specifications. Verify equivalent capacitance, voltage rating, and temperature coefficient before substitution.
