Nine Questions Answers to SMD Electronic Components Products

1. How do you distinguish the error of resistance?

Answer: The error of the resistance can be seen on the silk screen. The three digits above indicate 5% error, and the above four digits indicate 1% error.

2. Is the volume of the 3216 capacitor larger than that of the 1206?

Answer: 3216 is the metric system and 1206 is the imperial system. The two algorithms are the same size. (Metric/English 1005/0402 1608 /0603 2012/0805 3216/1206).

3. What is the SMD diode IN4007 SOD-123 typing?

Answer: The type on the chip diode IN4007 SOD-123 is D7.

4. How much R does 20R5 mean when typing on the resistor?

Answer: 20R5 is 1% resistance, which is 20.5R.

5. Is the tantalum capacitor better black or yellow?

Answer: There are two types of tantalum capacitors-tantalum manganese dioxide capacitors and tantalum polymer capacitors. U.S. tantalum capacitors are usually yellow, while Japan and others like to use black. In fact, the color has nothing to do with performance. Tantalum polymer capacitors have excellent high frequency characteristics and are expensive.

6. Hello, I would like to ask if the 0R resistance has a 1% error?

Answer: Hello! 0R resistance has no 1% error, only 5% error.

7. Hello, do you have 0201 small-size chip capacitors?

Answer: Hello! 0201 chip capacitors are available, if you want to know more, please contact us at 0769-86960218.

8. What are the specific models of the transistors typed as Y1 and Y2?

Answer: Type Y1 is SMD Transistor SS8050, Type Y2 is SMD Transistor SS8550, and the package is SOT-23.

9. Why can't the tantalum capacitor be connected reversely?

Answer: Because tantalum capacitors have positive and negative poles. The marked end is the positive electrode, and the other end is the negative electrode. The positive electrode of the long tantalum leg of the lead wire will not work if the tantalum capacitor is connected reversely.
