1206J1000472MXTE01

Overview

The Knowles Syfer 1206J1000472MXTE01 is a surface-mount feed-through capacitor designed for EMI suppression. It features a capacitance of 0.047 µF with a ±20% tolerance and a DC voltage rating of 100 V. The component utilizes X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package measuring 3.20 mm x 1.60 mm, it supports a maximum current of 300 mA and provides an insertion loss of 40 dB at 100 MHz.

Feature Summary

• Three-terminal feed-through architecture enables effective common-mode noise filtering directly on the trace.
• High current handling capability allows integration into power lines without signal degradation.
• Compact 1206 footprint facilitates dense PCB layout while maintaining robust electromagnetic interference suppression.

Applications

• Power supply input filtering for electronic equipment
• EMI suppression in high-speed digital circuit interfaces
• Noise reduction in automotive electronics systems

Procurement Notes

Verify the specific suffix TE01 against official manufacturer documentation to confirm terminal configuration and packaging details. Ensure compatibility with automated pick-and-place equipment regarding the 1206 package dimensions. Cross-reference the X7R dielectric characteristics with application thermal requirements to validate performance stability across the specified operating temperature range.

Selection Notes

Select this component when integrated EMI filtering is required in space-constrained designs. The three-terminal structure offers superior high-frequency attenuation compared to standard two-terminal capacitors. Consider the 300 mA current rating to ensure safe operation under peak load conditions without exceeding thermal limits defined by the X7R material properties.
