Frequently Asked Questions
Q: What is an HC-49S quartz crystal resonator and how does it work?
A: An HC-49S quartz crystal resonator is a passive electronic component that vibrates at a precise frequency (9 MHz in this case) when voltage is applied. It is used to provide a stable clock signal for microcontrollers and digital circuits. Being passive, it requires external load capacitors (typically 22pF) to oscillate correctly in your circuit.
Q: Are these 9MHz quartz crystals compatible with Arduino and AVR microcontrollers?
A: Yes. The HC-49S 9MHz crystal resonators are fully compatible with Arduino boards, AVR microcontrollers (such as ATmega series), PIC chips, STM32, and most other common microcontroller platforms that support an external crystal clock source. Simply connect the crystal between the XTAL1 and XTAL2 pins with appropriate load capacitors.
Q: Why buy a 100-piece pack of quartz crystal resonators?
A: A 100-piece bulk pack is perfect for electronics hobbyists, PCB designers, educators, and repair technicians who need a reliable supply on hand. Having extras ensures you can prototype freely, replace faulty components quickly, and complete production runs without delays — all at a cost-effective per-unit price.
