The 16 MHz Crystal Oscillator is a precision frequency control component that generates a stable 16 MHz clock signal, essential for microcontrollers and timing circuits. It is most commonly used in Arduino UNO, ATmega328P, ESP32, STM32, and other development boards, providing accurate timing for program execution, communication protocols, and data synchronization. Available in HC-49 (through-hole) packages as well as SMD (surface-mount) variants, the 16 MHz crystal oscillator offers low power consumption, high stability, and compact size. It is widely used in IoT devices, robotics, embedded systems, communication circuits, and consumer electronics. NeoGiga India supplies genuine, RoHS-compliant 16 MHz crystals with ±10ppm to ±30ppm frequency tolerance, making them suitable for students, makers, R&D labs, OEMs, and industries.
