0805J1000391MCTE01

Overview

The Knowles Syfer 0805J1000391MCTE01 is a three-terminal EMI filter capacitor in an 0805 surface-mount package. It features a 390 pF capacitance with a ±20% tolerance and a 100 VDC voltage rating. The component utilizes C0G/NP0 (1B) dielectric material for stable performance across temperatures ranging from -55°C to +125°C. It employs nickel barrier terminations with 100% tin plating and is supplied in reel packaging.

Feature Summary

• Three-terminal architecture designed for effective electromagnetic interference filtering
• C0G/NP0 dielectric ensures high stability and low loss characteristics
• Nickel barrier termination system provides robust solderability and reliability

Applications

• High-frequency signal line filtering
• Power supply noise suppression
• EMI reduction in sensitive electronic circuits

Procurement Notes

Verify the specific suffix E01 against official documentation to confirm the three-terminal configuration, as standard two-terminal variants exist within the same series. Ensure compatibility with automated pick-and-place equipment due to the reel packaging format. Confirm RoHS compliance status for your target market regulations before finalizing procurement.

Selection Notes

Select this component when space-constrained EMI filtering is required in the 0805 footprint. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Ensure the circuit operates within the specified temperature range and voltage limits to maintain capacitance stability and prevent dielectric breakdown.

Part Context

This part belongs to the Knowles Syfer MLCC High Reliability series, specifically engineered for demanding environments. The 0805J prefix indicates the case size and voltage class, while the MCTE01 suffix defines the specific termination and packaging details. It is distinct from standard general-purpose MLCCs by its specialized three-terminal construction.

Replacement Considerations

Direct substitutes must match the three-terminal EMI filter topology and 0805 dimensions. Verify that alternative parts offer equivalent C0G/NP0 dielectric properties and compatible termination materials to ensure reliable soldering and thermal performance.
