0805J0500123MXTE07

Overview

The Knowles Syfer 0805J0500123MXTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-frequency applications. It features a capacitance of 12 nF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes X7R dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 0805 (2012 metric) package, it incorporates a three-terminal EMI filter structure with nickel barrier and 100% tin terminations.

Feature Summary

• Three-terminal EMI filter architecture for enhanced noise suppression
• X7R dielectric material for thermal stability
• Nickel barrier and 100% tin termination system

Applications

• High-frequency signal line filtering
• Power supply decoupling in noisy environments
• EMI suppression in compact electronic modules

Procurement Notes

Verify the specific suffix MXTE07 against official datasheets to confirm the three-terminal EMI filter configuration and termination plating. Ensure compatibility with automated pick-and-place equipment regarding the reel packaging format. Cross-reference the manufacturer part number directly with Knowles Syfer documentation to validate the exact electrical characteristics and physical dimensions before integration.

Selection Notes

Select this component when space-constrained designs require integrated EMI filtering capabilities alongside standard decoupling functions. The 0805 footprint allows for dense PCB layouts while maintaining robust noise attenuation. Consider the X7R temperature coefficient for applications experiencing moderate thermal variations within the specified operational range.

Part Context

This component belongs to the Knowles Syfer XT series of MLCCs, which are engineered specifically for electromagnetic interference mitigation. Unlike standard two-terminal capacitors, this three-terminal design provides superior high-frequency performance by minimizing parasitic inductance, making it suitable for sensitive digital and RF circuits requiring clean power integrity.
