0805J0250821MXTE01

Overview

The Knowles Syfer 0805J0250821MXTE01 is a high-reliability multilayer ceramic capacitor (MLCC) designed for surface-mount applications. It features an 0805 (2012 metric) package with C0G (NP0) dielectric characteristics, ensuring stable performance across varying conditions. The component offers a capacitance of 820 pF with a tolerance of ±20%, rated for 25 VDC. It operates within a temperature range of -55°C to +125°C and utilizes nickel barrier end terminations with 100% tin plating.

Feature Summary

• High reliability construction suitable for demanding electronic environments
• C0G (NP0) dielectric provides minimal capacitance variation with temperature and voltage
• Three-terminal EMI filter design integrated into the MLCC structure
• Nickel barrier termination system ensures robust solder joint integrity

Applications

• EMI filtering in high-frequency signal lines
• Coupling and decoupling in precision analog circuits
• Applications requiring stable capacitance under thermal stress
• Board-flex sensitive designs utilizing three-terminal structures

Procurement Notes

Verify the specific suffix MXTE01 against official Knowles Syfer documentation to confirm the three-terminal EMI filter configuration and termination material. Ensure compatibility with standard 0805 footprints while accounting for the additional center terminal required for the feed-through architecture. Cross-reference RoHS compliance status directly from the manufacturer's datasheet prior to integration.

Selection Notes

Select this component when high-frequency noise suppression is critical alongside standard capacitive functions. The three-terminal topology offers superior high-frequency performance compared to standard two-terminal MLCCs. Consider the 0805 footprint constraints and ensure PCB layout supports the unique pin arrangement. Validate that the 25V rating meets the circuit's peak voltage requirements without derating issues.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC family, specifically engineered for industrial and aerospace-grade applications. The 0805J series denotes the 0805 case size with J indicating the voltage code prefix. The inclusion of EMI filter functionality distinguishes it from standard general-purpose capacitors, offering combined filtering and energy storage capabilities in a compact form factor.
