STDCSW5-25M

Overview

The NDK STDCSW5-25M is a surface-mount MHz crystal resonator designed for general electronic applications. It operates at a nominal frequency of 25 MHz with a frequency tolerance of ±15ppm and stability of ±30ppm. The component features an 8pF load capacitance and a maximum equivalent series resistance (ESR) of 60 Ohms. It utilizes a 4-SMD, no-lead package measuring 3.20mm x 2.50mm in footprint and 0.90mm in height. The device supports fundamental mode operation and functions within a temperature range of -40°C to +85°C.
