When I started to deal with Chinese electronics suppliers from websites like Alibaba, Aliexpress and Taobao, I discovered that there are huge amount of undiscovered tools from the Chinese market. They are not easily discovered, maybe due to the Chinese language barrier, especially when we deal with a Chinese website like Taobao or maybe because most of us are used to deal with known electronics distributors like Sparkfun.
This tool is used to discover the type and main features (like value and some other electrical characteristics) of the majority of discrete components like transistors, diodes, resistors, capacitors and other components.
This is useful when you have an unknown part. As you know a part with TO-220 package can be a BJT, a MOSFET or maybe something else. It is also useful when you know the basic function of the part in your hand and you need to know some of its characteristics.
- Can used with npn and pnp transistors, n-channel and p-channel mosfet, diodes (including double diodes), thyristors, transistors, resistors, capacitors and other components.
- Measuring the gate threshold voltage and gate capacitance of MOSFET.
- Amplification factor (gain) of the BJT and the base of the forward bias voltage.
- Getting the pinout of the component.
- Use 9v battery for power supply.
I found a video on Youtube for the same tool tested with a lot of components
That’s all for this time , see you on next post.
