1806J0500334MXTE01

Overview

The Knowles Syfer 1806J0500334MXTE01 is a surface-mount feedthrough capacitor designed for EMI suppression. It features a capacitance of 0.33 µF with a ±20% tolerance and a DC voltage rating of 50 VDC. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 1806 (4516 metric) package, it measures 4.5 mm in length, 1.6 mm in width, and 1.3 mm in height. This three-terminal device provides effective noise filtering for high-frequency interference.
