1806Y0500153MJTE07

Overview

The Knowles Syfer 1806Y0500153MJTE07 is a surface-mount multilayer ceramic feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 0.015 µF with a tolerance of ±20% and an X7R dielectric material. The component is rated for a DC voltage of 50V and operates within a temperature range of -55°C to +125°C. Housed in a compact 1806 (4516 metric) package, it integrates a three-terminal structure to provide effective electromagnetic interference filtering while maintaining board flexibility through its FlexiCap™ soft termination technology.

Feature Summary

• Integrates a three-terminal feed-through architecture to deliver superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• Utilizes FlexiCap™ soft termination technology to absorb mechanical stress, significantly reducing the risk of cracking during PCB bending or thermal cycling.
• Employs X7R dielectric characteristics to maintain stable capacitance performance across a wide industrial operating temperature range.

Applications

• High-reliability automotive electronics requiring AEC-Q200 compliance
• Board-flex sensitive circuit designs prone to mechanical strain
• Electromagnetic interference (EMI) filtering in signal lines

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm terminal configuration and termination plating specifications. Ensure that the selected packaging format aligns with automated assembly requirements. Cross-reference the RoHS status and environmental compliance data directly from the latest datasheet to meet regulatory standards for your target market.

Selection Notes

Select this component when circuit design demands both robust EMI suppression and enhanced mechanical durability. The combination of feed-through topology and flexible terminations makes it suitable for applications where space constraints limit filter size but reliability under physical stress remains critical. Confirm that the 50V rating adequately covers peak transient voltages in the application environment.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ series, which specializes in high-reliability ceramic capacitors featuring compliant terminations. The series addresses common failure modes associated with rigid MLCCs in dynamic environments. As a feed-through device, it offers distinct advantages over conventional decoupling capacitors by providing lower parasitic inductance and improved grounding paths for noise currents.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 0.015µF capacitance, 50V rating, and three-terminal feed-through structure. Verify that any alternative also incorporates soft termination technology if board flex sensitivity is a design constraint. Standard two-terminal replacements will not provide equivalent EMI performance or mechanical resilience.
