1206Y0500563MXTE01

Overview

The Knowles Syfer 1206Y0500563MXTE01 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a 0.056 µF capacitance with ±20% tolerance and a 50 VDC voltage rating. Utilizing X7R dielectric material, the component operates within a temperature range of -55°C to +125°C. The device employs FlexiCap™ technology with flexible terminations to enhance mechanical reliability against board stress. Packaged in a standard 1206 (3216 metric) footprint, it supports reflow soldering processes without assembly changes.

Feature Summary

• Integrates FlexiCap™ flexible termination technology to accommodate significant board bending and thermal cycling stress without cracking.
• Functions as a pass-through EMI filter, providing signal integrity protection through its internal conductive structure.
• Constructed with X7R ceramic dielectric to maintain stable electrical performance across wide industrial temperature variations.

Applications

• High-speed digital signal line filtering in communication equipment
• Power supply input/output decoupling in automotive electronics
• EMI suppression in aerospace and defense circuitry

Procurement Notes

Verify the specific suffix 'E01' against official datasheets to confirm terminal configuration and packaging details. Ensure compatibility with RoHS3 standards if required by project specifications. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Validate that the 1206 footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when high mechanical robustness is required alongside effective high-frequency noise attenuation. The FlexiCap™ feature makes it suitable for applications involving vibration or flexing substrates. Compare X7R characteristics against C0G/NP0 options if tighter capacitance stability over temperature is necessary. Ensure the 50V rating exceeds the maximum DC bias voltage present in the circuit application.

Part Context

This part belongs to the Knowles Syfer FlexiCap™ series, which specializes in multilayer ceramic capacitors with proprietary flexible terminations. The series is engineered to outperform conventional MLCCs in mechanical durability. The 1206Y prefix indicates the 1206 case size and general product family classification within the manufacturer's portfolio.

Replacement Considerations

Direct substitutes include other 1206 feed-through capacitors from Knowles Syfer, such as the 1206Y0500563MXTE03. Verify that alternative parts match the 0.056 µF capacitance, 50V rating, and X7R dielectric type. Ensure replacement components also feature compatible flexible termination structures if mechanical stress resistance is critical.

FAQ

What is the primary function of the FlexiCap™ technology in this component?

FlexiCap™ utilizes a proprietary flexible termination material that allows the capacitor to withstand greater degrees of board bending and thermal cycling compared to standard rigid terminations, thereby increasing mechanical reliability.

Is this component classified as a standard capacitor or a filter?

It is classified as a feed-through or pass-through capacitor, functioning primarily as an EMI filter component rather than a simple energy storage device.
