NX3215SA is a SMD crystal with a thickness of only 0.8mm. The sales volume of SMD crystal is NO1. It is widely used in clock display, Bluetooth module, Remote control and many other electronic products. The metal shell makes the product have better impact resistance, heat resistance, and environmental resistance during operation and operation. It is one of its advantages. The most important thing is that it is small, thin and light, which meets the current development trend of the electronic market. . NX3215SA crystal 
oscillator The length and width dimensions of the NX3215SA crystal oscillator are 3.2*1.5mm. The two-pin quartz crystal oscillator only corresponds to the frequency of 32.768KHZ, and the corresponding load capacitance is 6PF, 9PF, and 12.5PF. For crystal products, different parameters correspond to different product part numbers. The corresponding part numbers of NDK crystal oscillator NX3215SA are as follows
6PF：NX3215SA-32.768K-STD-MUA-14
9PF：NX3215SA-32.768K-STD-MUA-9
12.5PF：NX3215SA-32.768K-STD-MUA-8
12.5PF：NX3215SA-32.768K-STD-MUS-2
The above two different models are given for the NX3215SA crystal oscillator with the same frequency of 32.768K and the same load capacitance of 12.5PF, then the NX3215SA-32.768K-STD-MUA-8 crystal oscillator and the NX3215SA-32.768K-STD-MUS-2 crystal oscillator Where is the performance difference between.
NX3215SA-32.768K-STD-MUA-8 crystal oscillator is used in AV, OA and communication products, and the operating temperature is -40 to 85°C; NX3215SA-32.768K-STD-MUS-2 crystal oscillator is used in automotive electronics and has higher operating temperatures. -40 to 125°C is the temperature characteristic of the product. Don't misuse the model number because of the negligence of the letters.
