1206J0250184MJTE07

Overview

The Knowles Syfer 1206J0250184MJTE07 is a multilayer ceramic capacitor (MLCC) designed as a surface-mount EMI filter. It features a 3-terminal architecture with a nickel barrier and 100% tin termination, housed in a 1206 (3216 metric) package. The component offers a capacitance of 180 nF with a tolerance of ±20%, utilizing an X7R dielectric material. It is rated for a DC voltage of 25 VDC and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Integrates a 3-terminal feed-through structure to provide effective electromagnetic interference filtering in compact designs.
• Utilizes a nickel barrier termination system combined with 100% tin plating for enhanced solderability and reliability.
• Employs X7R dielectric characteristics to maintain stable capacitance performance across the specified operating temperature range.

Applications

• High-frequency noise suppression in electronic circuits
• EMI filtering for power supply lines
• Signal integrity protection in communication modules

Procurement Notes

Verify the specific termination configuration and terminal count against schematic requirements before procurement. Confirm that the 3-terminal footprint matches the PCB layout design. Ensure the voltage rating and capacitance values align with circuit specifications. Check for RoHS compliance documentation if required by project standards. Validate availability through authorized distributors due to potential supply constraints.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete components. The 3-terminal design reduces parasitic inductance compared to standard 2-terminal capacitors. Consider the physical dimensions of the 1206 package for space-constrained applications. Evaluate the X7R temperature coefficient for stability needs within the operational environment.
