0805J0500123MXTE01

Overview

The Knowles Syfer 0805J0500123MXTE01 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 12 nF with a tolerance of ±20% and utilizes 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 an 0805 (2012 metric) package, it incorporates a three-terminal architecture for EMI filtering applications.

Feature Summary

• Three-terminal structure provides enhanced electromagnetic interference suppression capabilities
• Utilizes X7R dielectric for stable performance across the operating temperature range
• Designed as a feed-through capacitor for effective noise reduction in signal lines

Applications

• EMI filtering in high-speed digital circuits
• Noise suppression in RF signal paths
• Power line filtering in compact electronic modules

Procurement Notes

Verify the specific suffix 'E01' confirms the three-terminal EMI filter configuration rather than a standard two-terminal MLCC. Confirm the package dimensions match the 0805 footprint requirements. Ensure the X7R dielectric characteristics align with the thermal stability needs of the target application environment.

Selection Notes

Select this component when integrated EMI filtering is required without occupying additional board space for discrete filters. The three-terminal design offers superior high-frequency attenuation compared to standard capacitors. Verify that the 50V rating exceeds the peak transient voltages present in the circuit to ensure long-term reliability.

Part Context

This part belongs to the Knowles Syfer 0805J series of low-profile MLCCs. The 'E01' suffix specifically denotes the three-terminal feed-through variant. This distinguishes it from standard two-terminal capacitors like the 0805J0500123MXT, providing dedicated filtering functionality within the same physical envelope.

Replacement Considerations

Direct substitutes must maintain the three-terminal EMI filter topology. Standard two-terminal 12nF 50V 0805 capacitors are not functionally equivalent due to the lack of shielding ground connection.
