1206J1000153MJTE03

Overview

The Knowles Syfer 1206J1000153MJTE03 is a feed-through multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 0.015 µF with a DC voltage rating of 100 VDC and a tolerance of ±20%. The component utilizes C0G (NP0) dielectric material, ensuring stability across an operating temperature range from -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it integrates a built-in 50 mA fuse function for circuit protection. The device is packaged in reels for automated assembly processes.

Feature Summary

• Integrates a built-in fuse function providing overcurrent protection within the capacitor structure
• Utilizes C0G (NP0) dielectric material for high thermal stability and low loss characteristics
• Designed as a feed-through component to combine filtering and fusing capabilities in a single SMD package

Applications

• High-reliability electronic circuits requiring integrated surge protection
• Automotive electronics systems adhering to AEC-Q200 standards
• Industrial control equipment needing compact filter-fuse solutions

Procurement Notes

Verify the specific suffix 'MJTE03' against official Knowles Syfer documentation to confirm the exact fuse current rating and termination specifications. Ensure compatibility with PCB pad layouts designed for feed-through components rather than standard MLCCs. Confirm RoHS compliance status through the manufacturer's environmental declarations prior to integration into regulated assemblies.

Selection Notes

Select this component when space constraints prevent using discrete capacitors and fuses. The 1206 footprint offers a balance between current handling capacity and board area. Consider the 50 mA fuse threshold relative to normal operating currents to avoid nuisance blowing. Verify that the C0G dielectric meets the required capacitance stability for the specific frequency range of the application.

Part Context

This part belongs to the Knowles Syfer J-series of high-reliability feed-through capacitors. These components are engineered for demanding environments where traditional discrete protection devices are impractical. The series is widely recognized in automotive and industrial sectors for its ability to suppress electromagnetic interference while providing robust circuit protection against transient overcurrent events.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-referencing requires matching the 1206 footprint, 100V rating, 0.015 µF capacitance, and specifically the 50 mA internal fuse characteristic.
