1206J0500474KXT – SYFER TECHNOLOGY

Overview

The Knowles Syfer 1206J0500474KXT is a high-performance 0.47 µF, 50V ceramic capacitor designed for robust signal integrity applications. Its X7R dielectric offers a stable capacitance across a broad temperature range (-55°C to 125°C), crucial for maintaining predictable circuit behavior in demanding environments. A key design consideration for this component is the trade-off between volumetric efficiency and dielectric loss at higher frequencies; while X7R provides good temperature stability, designers must account for potential ESR increases in sensitive RF circuits, often necessitating parallel filtering or careful impedance matching.
