0805Y0500273MJTE07

Overview

The Knowles Syfer 0805Y0500273MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) in an 0805 (2012 Metric) package. It features a capacitance of 0.027 µF with a ±20% tolerance and a DC voltage rating of 50V. The dielectric material is X7R, providing stable performance across a temperature range of -55°C to +125°C. This component utilizes FlexiCap technology with nickel barrier and 100% tin terminations to enhance mechanical reliability.

Feature Summary

• FlexiCap soft termination design reduces stress on the capacitor body and PCB pads during board flexing or thermal cycling.
• Nickel barrier layer between the electrode and termination metal prevents solder wicking and improves joint integrity.
• X7R dielectric offers high volumetric efficiency and reliable capacitance stability over the specified operating temperature range.

Applications

• High-reliability automotive electronics requiring AEC-Q200 compliance
• Applications sensitive to board flexibility and mechanical stress
• General-purpose decoupling and filtering in industrial equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm termination type and packaging details. Ensure compatibility with RoHS3 regulations if required by your assembly process. Cross-reference the Mouser number 843-05Y0500273MJTE07 for accurate distributor identification and availability status before placing orders.

Selection Notes

Select this component when mechanical robustness is critical due to its FlexiCap termination structure. The 0805 footprint provides a balance between capacitance density and handling ease. The X7R dielectric is suitable for general applications where moderate temperature stability is sufficient, while the 50V rating allows for standard low-voltage circuit designs.

Part Context

This part belongs to the Knowles Syfer FlexiCap series, designed specifically for high-reliability environments. The series emphasizes durability under mechanical stress, making it distinct from standard MLCCs. It is widely used in sectors demanding long-term stability and resistance to cracking caused by PCB deformation.

Replacement Considerations

Direct substitutes within the same series include parts with identical capacitance and voltage ratings but different tolerances or termination styles. Verify that any replacement maintains the FlexiCap feature if mechanical stress relief is required. Check for equivalent AEC-Q200 qualification if automotive use is intended.
