What is the difference between WQS-SMD7050 crystaland WQS-OSC7050 oscillator?
"SMD" is the abbreviation of Surface-Mount Device, and "7050" refers to the size of this crystal, which is 7.0 x 5.0 mm.
Usually, WQS-SMD7050 crystal refers to crystal resonator (passive crystal), while WQS-OSC7050 oscillator refers to crystal oscillator (active oscillator). As the clock source in electronic devices, WQS-SMD7050 crystal and WQS-OSC7050 oscillator provide accurate clock signals for electronic devices.
In electronics, circuits containing transistor components are usually called "active circuits" (such as active speakers, active filters, etc.), while circuits composed only of resistors and capacitors are called "passive circuits". The crystal in computers are also divided into two types: passive crystal and active crystal oscillator. A passive crystal is a non-polar component with 2 pins. It needs the help of a clock circuit to generate an oscillation signal and cannot oscillate by itself. An active crystal oscillator has 4 pins and is a complete oscillator, which, in addition to a quartz crystal, also contains transistors and resistors and capacitors.
