9 pin resistor, what resistor????

This is a "row resistor", in which 8 resistors with the same resistance value are integrated. One of the eight resistors is connected together, and this connection is the first foot on the left side marked with a dot. As shown in Fig.

The word 103J, the preceding 103 indicates that the resistance of the 8 resistors is 10k ohms.

j indicates that the resistance error is 5%.

It is a resistor, and the upper end of all resistors is connected to one point, that is, the leftmost pin is the common end, and this kind of resistor is generally used for devices with OC or OD (open collector and open drain) output, which is convenient for pull-up setting.

This is a resistor, that is, 8 resistors side by side. One is the common side, and the other eight pins are the ports that lead out the 10k ohm resistor from the common side, and 103j refers to 10k.

This is a resistor row, commonly known as a resistor row, which is often used in single-chip microcomputers and other circuits, and is mainly used in pull-up resistor occasions.

If you put the resistor horizontally, 1 pin is on the left, and from left to right it is 2, 3, 4....9 feet. Starting from 1 pin, the resistance to any pin is equal (such as 1-2, 1-6, 1-9, etc.), the resistance value of this resistance is 10k, and the accuracy is plus or minus 5%.

You can draw 8 resistors, and connect one end of each resistor to be 1 pin of this resistor, and the others are 2-9 pins.

This resistor is called a row resistor, 1 common terminal (with a marker point), 8 resistance terminals, the distance between pins = 100in, and the package is resin.

The pins are, drain D and source S, gate G.

The function of drain D and source S is similar: it is a voltage-controlled semiconductor device, which has the advantages of high input resistance (10 8 10 9), low noise, low power consumption, large dynamic range, easy integration, no secondary breakdown, and wide safe working area.

Gate: One or more electrodes with a fine wire mesh or helical shape arranged between the anode and the cathode in a multipolar electron tube, which play the role of controlling the electric field strength on the surface of the cathode to change the cathodic radiation current or capture secondary radioactive electrons.

The 8 pins are made of two tubes in one chip, and the pin arrangement depends on the specific model.

Conductive silver or gold plating and tin or lead-tin alloys.

It is generally tinned, which is conducive to soldering and is not easy to oxidize, and the cost is low.

Yes, the thickness of the resistor pin depends on the power pin collapse rate of the resistor, look at your picture, it is a small power, the electric talk is small, the weight is light, no problem. The pins are thinned as a result of improved craftsmanship.

Try it, what can be attracted with a magnet is iron, and if it can't be copper.

Regardless of copper and iron, the outside is generally tinned, otherwise it is not easy to solder.

There are fewer iron ones now, mostly copper. Only ultra-high-power ceramic resistors may be fixed with iron rings because the resistors themselves are too heavy.
