1206J0500823MJTE07

Overview

The Knowles Syfer 1206J0500823MJTE07 is a multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features an X7R dielectric material with a capacitance of 82 nF and a tolerance of ±20%. The component is rated for a DC voltage of 50 VDC and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it utilizes a three-terminal architecture with nickel barrier and 100% tin terminations. This configuration functions as an EMI filter, providing enhanced electromagnetic interference suppression capabilities compared to standard two-terminal capacitors.

Feature Summary

• Three-terminal EMI filter architecture for superior high-frequency noise attenuation
• Nickel barrier termination system ensuring reliable solderability and corrosion resistance
• X7R dielectric composition providing stable capacitance characteristics across the operating temperature range

Applications

• Electromagnetic interference filtering in sensitive electronic circuits
• Power supply input and output stages requiring noise suppression
• Signal line protection in communication equipment

Procurement Notes

Verify the specific ordering suffix and termination finish against the manufacturer's latest datasheet to ensure compatibility with your assembly process. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the part number with authorized distributors to validate current availability and lead times, as supply chain conditions may vary.

Selection Notes

Select this component when integrated EMI filtering is required without occupying additional board space for discrete filters. The three-terminal design offers better high-frequency performance than standard MLCCs. Ensure the PCB layout supports the specific grounding requirements of the center terminal to maximize filtering effectiveness. Verify that the 50V rating meets the circuit's peak voltage demands.

Part Context

This component belongs to the Knowles Syfer 1206J series of general-purpose and specialized MLCCs. The 'J' designation typically indicates a Class 2 dielectric like X7R, while the 'T' in the suffix often denotes specific termination or packaging variations. It is part of a broader family of surface-mount capacitors designed for industrial and commercial applications requiring robust performance.

Replacement Considerations

Direct replacements must match the 1206 footprint, 82nF capacitance, 50V rating, and three-terminal EMI filter structure. Standard two-terminal X7R capacitors are not functionally equivalent due to inferior high-frequency impedance characteristics. Verify that any substitute maintains the same nickel barrier termination specification for soldering compatibility.
