1210J0500474KXT – SYFER TECHNOLOGY

Overview

The Knowles Syfer 1210J0500474KXT is a high-performance ceramic capacitor designed for robust signal integrity and filtering applications. Its primary function is energy storage and AC signal decoupling, with a critical operational characteristic being its X7R dielectric, offering a stable capacitance across a wide temperature range. A key design consideration for engineers is the trade-off between X7R’s temperature stability and its susceptibility to DC bias, where capacitance can decrease significantly under applied voltage, necessitating careful voltage derating in sensitive circuits.

Key Features

• Capacitance: 0.47 µF
