Description:
This is a quartz crystal oscillator specifically designed to provide the precise frequency required for real-time clock applications.
The "32.768kHz" frequency is chosen because it's easily divisible to produce a 1-second pulse, which is essential for accurate timekeeping.
"RTC Crystal" indicates its primary use in real-time clock circuits.
"T38" refers to a package type.
They are sold in varying quantities, in this case a pack of 2.
Key Features:
- Accurate Timekeeping: Provides a stable and precise frequency for RTCs.
- Low Frequency: 32.768kHz, ideal for low-power applications.
- Stability: Quartz crystals offer excellent frequency stability over a wide temperature range.
- Low Power Consumption: Essential for battery-powered RTC devices.
- T38 package: a common through hole package.
Applications:
- Real-Time Clocks (RTCs): Used in electronic devices to maintain accurate time.
- Computers and Laptops: Keeping track of system time.
- Embedded Systems: Timekeeping in microcontrollers and other embedded devices.
- Consumer Electronics: Watches, clocks, and other time-sensitive devices.
- Data Loggers: Timestamping recorded data.
- Automotive Electronics: Timekeeping in vehicle systems.
