1206Y0500153MJTE03

Overview

The Knowles Syfer 1206Y0500153MJTE03 is a feed-through multilayer ceramic capacitor in a 1206 (3216 metric) package. It features a capacitance of 0.015 µF with ±20% tolerance and a rated voltage of 50V DC. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range of -55°C to +125°C. Designed for high-reliability applications, it incorporates soft termination technology and a nickel barrier to enhance mechanical robustness against board flexing.

Feature Summary

• Integrated feed-through architecture providing combined capacitance and EMI filtering capabilities within a single surface-mount component.
• Soft termination construction designed to mitigate stress-induced cracking during PCB assembly and operation on flexible substrates.
• Nickel barrier electrode structure offering enhanced corrosion resistance and improved reliability in demanding environments.

Applications

• High-reliability aerospace and defense electronic systems requiring compact EMI suppression.
• Automotive electronics subject to mechanical vibration and thermal cycling.
• Industrial control boards where space constraints necessitate integrated filtering solutions.

Procurement Notes

Verify the complete part number including suffixes to ensure correct termination and barrier specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference lead times and availability directly with authorized distributors as stock levels fluctuate. Ensure design compatibility with the specific feed-through pin configuration and current rating requirements of the target circuit.

Selection Notes

Select this component when board space is limited and simultaneous decoupling and noise filtration are required. The soft termination feature makes it suitable for rigid-flex or flexible PCB designs where standard terminations might fail under mechanical stress. Evaluate the 50mA current handling capability against circuit load requirements to prevent performance degradation.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability MLCCs featuring soft terminations. The 1206Y series designation indicates a standard 1206 footprint optimized for dense surface-mount layouts. The MJTE03 suffix identifies specific terminal and barrier characteristics distinct from standard MLCC variants.

Replacement Considerations

Direct substitutes must match the feed-through topology, 1206 footprint, and soft termination properties. Standard MLCCs lacking the internal feed-through structure or nickel barrier will not provide equivalent EMI filtering or mechanical resilience. Verify that any alternative maintains the same 50V rating and X7R temperature coefficient.
