1206J0500221MCTE07

Overview

The Knowles Syfer 1206J0500221MCTE07 is a surface-mount feed-through capacitor designed for high-frequency noise suppression. It features a capacitance of 220 pF with a voltage rating of 50 VDC and a tolerance of 20%. The component utilizes an X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) case size, it integrates a three-terminal structure with nickel barrier and 100% tin terminations. This design supports a rated current of 2 A, making it suitable for EMI filtering applications where compact footprint and high current handling are required.

Feature Summary

• Three-terminal feed-through architecture provides superior high-frequency noise attenuation compared to standard two-terminal capacitors.
• Integrated nickel barrier termination system enhances solderability and mechanical reliability during surface mount assembly.
• Capable of handling continuous currents up to 2 A while maintaining signal integrity in power lines.
• X7R dielectric composition offers consistent capacitance stability over the specified industrial operating temperature range.

Applications

• EMI filtering on DC power input lines in portable electronic devices
• Noise suppression in high-speed digital circuit power distribution networks
• Signal conditioning in automotive electronics requiring robust thermal performance

Procurement Notes

Verify the specific suffix 'MCTE07' against official Knowles Syfer documentation to confirm the presence of the nickel barrier termination and 100% tin plating. Ensure the selected variant matches the required 2 A current rating and 220 pF capacitance value for your specific circuit design. Cross-reference the package dimensions with your PCB footprint library to guarantee accurate placement and soldering compatibility.

Selection Notes

Select this component when space constraints necessitate a 1206 footprint but higher current handling than standard MLCCs allows. The three-terminal design is critical for applications demanding effective common-mode noise reduction. Verify that the 50 VDC rating exceeds the maximum peak voltage in the target application. Consider the X7R temperature coefficient if the operating environment experiences significant thermal fluctuations.

Part Context

This part belongs to the Knowles Syfer J-series of feed-through capacitors, which are engineered for compact EMI suppression. Unlike traditional discrete components, these integrated solutions combine filtering and mounting functions. The series is characterized by its ability to handle substantial currents within small surface-mount packages, addressing the trend toward miniaturization in modern electronics without compromising electrical performance or reliability standards.
