1206J0500390MCTE01

Overview

The Knowles Syfer 1206J0500390MCTE01 is a surface-mount feedthrough capacitor designed for high-frequency noise suppression. It features a capacitance of 39 pF with a tolerance of ±20% and a DC voltage rating of 50 VDC. The component utilizes C0G (NP0) dielectric material, ensuring stable performance across an operating temperature range of -55°C to +125°C. Housed in a standard 1206 (3216 metric) package, it integrates a nickel barrier termination system. This device provides effective electromagnetic interference filtering within compact board layouts.
