2N2222A by Texas Instruments is a small signal NPN bipolar junction transistor (BJT) with a max collector-emitter voltage of 40V and a max collector current of 0.8A. It is commonly used for switching applications due to its fast turn on/off times (35ns/285ns) and high transition frequency (300MHz).
LFXTAL025159REEL by IQD Frequency Products is a 32.768 kHz crystal oscillator with 20 ppm frequency tolerance and 40,000 ohm series resistance. It is ideal for applications requiring precise timekeeping, such as real-time clocks in IoT devices or microcontrollers in wearables. The surface-mount design with a drive level of 1 uW makes it suitable for compact electronic systems.
