YXC – HC-49US 4.192MHZ 20PF 20PPM 2Pin DIP Through-Hole Crystal

The YXC-HC-49US 4.192MHz crystal is a through-hole crystal oscillator commonly used in electronic circuits requiring precise timing or clock signals. Here’s what each part of its name and specifications typically mean:

• YXC: This likely denotes the manufacturer or brand of the crystal.
• HC-49US: This is the package type of the crystal. HC-49US is a common through-hole package style for crystals.
• 4.192MHz: This is the resonant frequency of the crystal oscillator, indicating the frequency at which it vibrates.
• 20PF: This refers to the load capacitance, indicating the external capacitance required for proper operation. In this case, it’s 20 picofarads.
• 20PPM: This stands for “Parts Per Million” and indicates the frequency stability or tolerance of the crystal oscillator. A value of 20PPM means that the frequency can vary by up to 20 parts per million from the specified frequency.
• 2Pin DIP Through-Hole: This indicates that the crystal has two leads and is designed for through-hole mounting on a printed circuit board (PCB).

Overall, this crystal oscillator is suitable for applications where a stable clock signal or timing reference is required, such as in microcontrollers, microprocessors, communication systems, and various other electronic circuits. The specified frequency of 4.192MHz and the stability of 20PPM make it useful in applications requiring precise timing.
