1206Y1000472MJTE07

Overview

The Knowles Syfer 1206Y1000472MJTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 4700 pF with a voltage rating of 100 V and a tolerance of ±20%. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Packaged in a 1206 (3216 Metric) footprint, it incorporates a three-terminal architecture with flexible end terminations to enhance mechanical reliability under board flex conditions.

Feature Summary

• Three-terminal feed-through architecture provides superior high-frequency EMI filtering performance compared to standard two-terminal capacitors.
• Flexible soft termination design mitigates stress during PCB bending, ensuring durability in mechanically sensitive applications.
• Nickel barrier construction supports robust solderability and long-term environmental stability.

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF circuit noise suppression

Procurement Notes

Verify the complete part number including the suffix to confirm specific termination and packaging configurations. Ensure compatibility with RoHS directives if required by your assembly standards. Cross-reference datasheet specifications against your operational voltage and temperature requirements before integration.

Selection Notes

Select this component when high-frequency attenuation is critical and mechanical flexibility is required. The three-terminal design offers lower parasitic inductance than standard MLCCs. Consider the 1206 footprint constraints and ensure adequate clearance for the three-pad layout on the PCB.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with compliant terminations. The series targets applications prone to mechanical stress, such as automotive electronics and portable devices, combining reliable electrical performance with enhanced physical resilience.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 4700 pF capacitance, 100V rating, and three-terminal feed-through structure. Verify that alternative parts also feature flexible terminations if board flex resistance is a requirement.

FAQ

What is the primary advantage of the three-terminal design?

The three-terminal configuration significantly reduces parasitic inductance, enabling more effective high-frequency noise suppression compared to conventional two-terminal capacitors.

How does the flexible termination benefit the component?

The flexible end terminations absorb mechanical stress caused by PCB bending or thermal cycling, reducing the risk of crack formation and maintaining electrical continuity.
