Through Hole Resistors

WW3FT20R0 is a kind of through-hole resistor, which refers to all types of resistors with leads that pass through the resistor from both sides for mounting purposes. They come in different forms including carbon film, metal oxide, wire-wound, and composition types.

Regarding their application fields, WW3FT20R0 resistors are mainly used in microprocessors, cell phones, speakers, amplifiers, and power supplies. They are especially suited for applications where space is limited and reliable performance and extended life time are required. Moreover, they are ideal for high-temperature applications and automated insertion processes.

As for their working principles, through hole resistors work by providing a predetermined amount of electrical resistance to an electrical or electronic circuit. It does this by using a thin wire of a known resistivity that is wound into a coil shape. The resistance of the resistor is determined by both the length of the wire and its cross-sectional area. Changing the length or the cross-sectional area of the wire, either manually or mechanically, will change the value of the resistor.

In addition, elements of through-hole resistors are also considered when describing their working principles. The terminals of a through-hole resistor are the connections placed on the ends of the resistor that a user connects their circuit with. The body or package is the outer casing that holds and protects the entire device. While it is usually made of ceramic or plastic, it is also possible to use metal bodies with metal oxide film resistors. Additionally, the leads or lead frame can be the standard round ones like with carbon film resistors, or the flat ones as with wire-wound and composition types.

In conclusion, the WW3FT20R0 is a through-hole resistor with multiple applications in industries like microprocessors, cell phones, and power supplies. Its resistance is determined by both the length and cross-sectional area of the thin wire, and it can be adjusted with elements like terminals, body, lead frame, and so on.
