1206J0250473MXTE01

Overview

The Knowles Syfer 1206J0250473MXTE01 is a surface-mount feed-through capacitor designed for EMI suppression. It features a 0.047 µF capacitance with a 25 VDC rated voltage and a 300 mA current rating. The component utilizes an X7R dielectric in a 1206 (3216 metric) package. It employs a three-terminal architecture with nickel barrier and 100% tin terminations to provide effective high-frequency noise filtering.

Feature Summary

• Three-terminal feed-through architecture for enhanced high-frequency EMI suppression
• Nickel barrier termination system ensuring reliable solderability and corrosion resistance
• X7R dielectric material providing stable capacitance characteristics across operating temperatures

Applications

• High-frequency noise filtering in electronic circuits
• EMI suppression in signal and power lines
• Protection of sensitive components from electromagnetic interference

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm terminal configuration and packaging details. Ensure that the selected variant matches the required current rating and voltage specifications for the target application environment. Cross-reference part numbers with authorized distributors to confirm availability and authenticity.

Selection Notes

Select this component when a three-terminal feed-through topology is required for superior high-frequency attenuation compared to standard two-terminal capacitors. Consider the 300 mA current rating and 25 VDC limit during circuit design. Evaluate the 1206 footprint constraints and ensure compatibility with the PCB pad layout designed for three-terminal devices.

Part Context

This component belongs to the Knowles Syfer XT series of multilayer ceramic capacitors. The series is characterized by its use of nickel barrier terminations, which offer improved reliability and solderability compared to traditional palladium-silver systems. The 1206J prefix indicates a general-purpose X7R dielectric variant within the 1206 package size family.
