0805J1000221MATE01

Overview

The Knowles Syfer 0805J1000221MATE01 is a surface-mount feed-through capacitor designed for high-frequency EMI suppression. It features a capacitance of 220 pF with a DC voltage rating of 100 V and a current rating of 300 mA. The component utilizes C0G/NP0 dielectric technology, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a compact 0805 (2012 metric) package, it integrates a three-terminal structure for effective noise filtering in sensitive electronic circuits.

Feature Summary

• Three-terminal feed-through architecture provides superior high-frequency EMI filtering compared to standard two-terminal capacitors.
• C0G/NP0 dielectric material ensures minimal capacitance variation over temperature and voltage changes.
• AEC-Q200 qualification confirms suitability for demanding automotive electronic environments.

Applications

• Automotive infotainment system power line filtering
• High-speed digital signal interface protection
• Sensitive RF circuit noise suppression

Procurement Notes

Verify the specific suffix MATE01 against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure design compatibility with the 300 mA current rating and 100 V DC limit. Confirm AEC-Q200 certification requirements are met for the target application environment before finalizing procurement specifications.

Selection Notes

Select this component when high-frequency noise attenuation is critical in space-constrained designs. The 0805 footprint allows for dense PCB layouts while maintaining robust filtering capabilities. Consider the 300 mA current handling capability relative to the circuit load to prevent performance degradation under operational stress.

Part Context

This part belongs to the Knowles Syfer MLCC family, specifically engineered as an EMI filter. Unlike general-purpose capacitors, this model integrates a grounded center terminal to shunt common-mode noise effectively. It represents a specialized solution within the broader ceramic capacitor portfolio, targeting applications requiring precise impedance control and high reliability.
