HC-49SMD-3P is a classic crystal package with a three-lead structure at the bottom. It is a self-excited oscillator crystal widely used in electronic devices. A three-lead crystal means that the bottom of the crystal has three pins, through which the crystal can be connected to other components on the circuit board. Due to the advantages of stable performance, small size and easy soldering, the HC-49SMD crystal is widely used in various electronic devices such as computers, communication equipment, control systems, etc. It is often used as a key component such as clock crystals, oscillators and timing controllers.
