The TZ1185A is a SMD Crystal Resonator manufactured by Tai-Saw Technology. It is RoHS compliant, SMD-3225_4P in size, and suitable for an IC circuit. The TZ1185A is a piezoelectric quartz crystal used to provide a precise frequency reference for the circuit's clock and timing functions. It has a frequency range between 10MHz and 50MHz, and excellent shock and temperature stability, allowing it to function reliably in a variety of environmental conditions. The TZ1185A is very tiny, making it suitable for tight spaces as required on modern PCBs.
