1206J0250683MJTE07

Overview

The Knowles Syfer 1206J0250683MJTE07 is a three-terminal multilayer ceramic capacitor (MLCC) designed for surface mount technology. It features a capacitance of 68 nF with a tolerance of ±20% and utilizes an X7R dielectric material. The component is rated for a DC voltage of 25 VDC and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it incorporates a nickel barrier termination system with 100% tin plating. This configuration supports its function as an EMI filter, providing effective noise suppression in compact electronic assemblies.

Feature Summary

• Three-terminal architecture enables integrated EMI filtering capabilities within the passive component structure.
• Nickel barrier termination system provides enhanced solderability and mechanical reliability for surface mount processes.
• X7R dielectric ensures stable capacitance performance across the specified industrial operating temperature range.

Applications

• High-frequency noise suppression in sensitive signal lines
• EMI filtering in compact consumer electronics assemblies
• Power line decoupling where space constraints limit discrete filter components

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm terminal composition and packaging format. Ensure the selected variant matches the required three-terminal footprint and nickel barrier specifications for your PCB layout. Cross-reference the RoHS compliance status with your assembly requirements before finalizing procurement orders.

Selection Notes

Select this component when circuit design requires combined capacitance and EMI filtering in a single surface-mount package. The 1206 form factor offers a balance between current handling capability and board space efficiency. Confirm that the 25V rating aligns with the maximum operating voltage of the target application to ensure long-term reliability under thermal stress conditions.

Part Context

This part belongs to the Knowles Syfer high-reliability MLCC portfolio, specifically engineered for demanding environments. The 1206J series designation indicates a standard 1206 case size with J-series manufacturing characteristics. As a specialized EMI filter capacitor, it differs from standard two-terminal capacitors by utilizing a third terminal to ground for superior high-frequency attenuation performance.

Replacement Considerations

Direct substitutes must match the 1206 footprint, 68nF capacitance, 25V rating, and three-terminal EMI filter topology. Verify compatibility of the nickel barrier termination system with existing reflow profiles. Generic two-terminal X7R capacitors are not suitable replacements due to the lack of integrated filtering functionality.
