1206Y1000392MJTE03

Overview

The Knowles Syfer 1206Y1000392MJTE03 is a feed-through capacitor designed for surface mount technology. It features a capacitance of 3900 pF with a voltage rating of 100 VDC and a tolerance of ±20%. The component utilizes a three-pad configuration within a 1206 (3216 metric) package, supporting a maximum current of 50 mA. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrated feed-through architecture providing electromagnetic interference filtering capabilities
• Three-pad surface mount design enabling direct signal line integration
• High-current handling capability suitable for power line applications

Applications

• Electromagnetic interference suppression in high-frequency circuits
• Power line filtering for sensitive electronic components
• Signal integrity protection in communication equipment

Procurement Notes

Verify the specific suffix 'MJTE03' against official datasheets to confirm the feed-through topology and three-pad footprint. Standard MLCCs share similar part numbers but lack the internal conductive structure. Confirm RoHS compliance and AEC-Q200 status if automotive qualification is required for your specific application environment.

Selection Notes

Select this component when integrated EMI filtering is required without adding discrete inductors or capacitors. Ensure the PCB layout accommodates the unique three-pad geometry distinct from standard two-terminal MLCCs. Verify that the 50 mA current rating exceeds the maximum expected operating current to prevent thermal failure.

Part Context

This component belongs to the Knowles Syfer feed-through capacitor series, which combines capacitance with low-inductance construction. Unlike standard multilayer ceramic capacitors, these devices are engineered to handle higher currents while maintaining stable performance across wide temperature ranges in compact surface-mount packages.

Replacement Considerations

Direct replacements require identical feed-through topology and three-pad footprints. Generic MLCCs cannot substitute this component due to the absence of internal conductive paths. Consult manufacturer cross-reference lists for verified equivalents with matching electrical and mechanical specifications.
