CL21B331KBANNNC – SAMSUNG

Overview

The SAMSUNG CL21B331KBANNNC is a high-performance ceramic capacitor designed for stable operation in demanding electronic circuits. Its primary function is energy storage and filtering, with its critical characteristic being the X7R dielectric, which offers a predictable capacitance change of ±15% over a wide temperature range of -55°C to 125°C. A key design consideration for this component is managing its dielectric’s inherent non-linearity; while X7R provides a good balance of temperature stability and cost, designers must account for potential DC bias effects, where applied voltage can significantly reduce effective capacitance, especially in applications with tight capacitance tolerances under load.
