1. Used capacitors can no longer be used, but can be removed as a periodic inspection to test electrical performance;
2. If the capacitor is charged, discharge it with a resistor of about 1kΩ before use;
3. If the capacitor is stored under conditions of more than 35 ° C and humidity greater than 70%, the leakage current may rise, and the rated voltage may be applied by a resistor of about 1 kΩ before use;
4. Confirm the rated capacity, voltage and polarity of the capacitor before installation;
5. Do not use capacitors that fall on the ground;
6. Do not use deformed capacitors;
7. The positive and negative lead spacing of the capacitor should match the position of the PC board soldering hole. If the capacitor is forcibly inserted into a circuit board whose hole pitch is not matched, stress will act on the lead wire, which may cause the capacitor to short-circuit or increase the leakage current;
8. Insert the capacitor pins or solder pins into the PC board during installation until the bottom of the capacitor is attached to the surface of the PC board.
9. Do not apply more than the specified mechanical pressure. When a pulling force is applied to the capacitor lead-out line, the pulling force acts on the inside of the capacitor, causing a short circuit inside the capacitor, and an open circuit or leakage current rises. The capacitor is soldered to the board and the capacitor is not shaken strongly.
USB 2.0 3.0 Flash Pen Drives FLASH Memory Pendrive USB Stick
1.What is the write speed ?
our USB 2.0 flash drive write speed is 5M/S - 10M/S or you will lucky to get 11M+.
Different device and different platform will affect a lot on the speed testing.
if you want to save 1GB film in our USB flash drive,that you need the time is 2 mins,it save your time.
2.Why the USB flash drive real capacity is not correct capacity?
Flash memory vendors are using decimal arithmetic:1MB = 1000KB,1G = 1000MB
calculated, the operating system using binary arithmetic:1MB = 1024KB,1GB = 1024MB;
so there are some differences between display capacity and nominal capacity of flash memory product
About capacity:
4GB=approximately 3.5GB-3.7GB
8GB=approximately 7.4GB-7.8GB
16GB=approximately 14GB-15GB
32GB=approximately 28GB-30GB
64GB=approximately 58GB-59GB
128GB=approximately 115GB-120GB
