Description
32.768kHz Quartz Crystal Oscillator YT-38 for RTC & Low-Power Embedded Systems
The 32.768kHz Quartz Crystal Oscillator YT-38 is a high-precision timing component engineered to provide an accurate and stable clock source for low-frequency electronic applications. Built using a tuning-fork quartz crystal, this oscillator is specifically designed for circuits requiring precise timekeeping while maintaining extremely low power consumption.
Operating at the industry-standard 32.768kHz frequency, the YT-38 crystal is the preferred clock source for Real-Time Clock (RTC) circuits. The frequency is ideal because it can be divided by binary counters to generate an accurate 1 Hz clock signal, making it perfect for digital clocks, calendars, timers, and battery-backed timekeeping systems.
Manufactured in a compact 3 × 8 mm 2-pin through-hole package, the YT-38 offers excellent mechanical durability, reliable electrical performance, and easy PCB integration. Its robust construction ensures stable operation over extended periods, making it suitable for both commercial and industrial electronic products.
The crystal delivers excellent frequency stability with low aging characteristics, helping maintain accurate time even in long-term operation. Its low current requirement makes it especially suitable for battery-powered devices where maximizing battery life is essential.
The 32.768kHz YT-38 crystal is widely used in microcontroller-based RTC circuits, wearable electronics, IoT sensor nodes, digital clocks, energy meters, medical devices, wireless communication equipment, and portable electronic products. It is compatible with many popular microcontrollers including STM32, AVR, PIC, MSP430, ESP32, and other processors that support an external RTC crystal.
Whether you’re designing a low-power embedded controller, developing an IoT device, building a digital clock, or replacing an RTC crystal in an existing circuit, the YT-38 32.768kHz Quartz Crystal Oscillator provides accurate timing, dependable operation, and long-term reliability.
