1812J1000154MJTE03

Overview

The Knowles Syfer 1812J1000154MJTE03 is a 0.15 µF feed-through capacitor with a 100V DC rating and ±20% tolerance. It utilizes X7R (2R1) dielectric technology in an 1812 (4532 metric) package. The component features nickel barrier terminations with 100% tin plating. It supports a continuous current of 50 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated feed-through architecture providing inherent electromagnetic interference filtering capabilities
• X2Y configuration design for enhanced noise suppression in compact surface-mount layouts
• Nickel barrier termination structure ensuring reliable solderability and mechanical stability

Applications

• High-frequency signal line protection in automotive electronics
• Power supply input filtering for sensitive integrated circuits
• Noise suppression in high-speed digital data transmission interfaces

Procurement Notes

Verify the specific suffix 'E03' against official datasheets to confirm the feed-through variant, as standard MLCCs share similar base codes. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure PCB pad layout matches the three-pad feed-through geometry specified in the manufacturer's mounting guidelines.

Selection Notes

Select this component when simultaneous decoupling and EMI filtering are required in space-constrained designs. The 1812 footprint allows for higher capacitance density compared to smaller packages. Verify that the 50 mA current rating exceeds the maximum expected signal or power line current to prevent thermal degradation during operation.

Part Context

This part belongs to the Knowles Syfer 1812J series, which focuses on high-reliability multilayer ceramic capacitors. The J code indicates a 100V voltage rating class. The specific model integrates feed-through functionality, distinguishing it from standard parallel-plate capacitors within the same voltage and capacitance family.

Replacement Considerations

Direct substitutes include other 1812 X7R feed-through capacitors with matching 0.15 µF capacitance and 100V ratings. Verify terminal compatibility and physical dimensions before substitution.
