Through Hole Resistors

In industrial electronic circuits, metal film resistors, wirewound resistors and carbon composition resistors are all considered as through-hole resistors. Resistance in these components is produced by the thin film applied to a ceramic substrate, winding of metal alloy wire, or powdered carbon material. The device is sealed in an epoxy coated package where it can handle high temperatures, vibration, and moisture.

One of the most common types of through-hole resistors is the TA303PA75R0JE. It is an insulated resistor with a value range of 0.75 ohms to 2.2 ohms, with a tolerance of up to 1%. It is rated up to a maximum power of 5 watts at 80°C, 5 watts at 55°C, or 10 watts at 40°C. The TA303PA75R0JE has a compact, cylindrical shape, and it is generally color coded. This makes it easy to identify its resistance value.

The application field of the TA303PA75R0JE is mainly in power electronics. Its main function is to reduce voltage or current to specific levels, limiting current through a circuit or providing adjustable voltage for adjustable power suppliers. Also these resistors can be used in a variety of other applications such as transformers, relays, contactors, logic modules and other circuits.

The working principle behind the TA303PA75R0JE is quite simple. It works by limiting the flow of current through the circuit, and in doing so, it prevents the current from surpassing safe levels. It does this by providing an impedance which limits the current flow through the circuit. This impedance is determined by the resistance value of the TA303PA75R0JE, and can be adjusted by changing its resistance value.

To ensure that the TA303PA75R0JE offers excellent performance and accuracy even under demanding conditions, it is highly recommended to mount it on a heat-conductive substrate such as ceramic, aluminum oxide, or epoxy. Doing this will ensure that the resistor can dissipate the heat better, and thus provide better performance.

In conclusion, the TA303PA75R0JE is a very reliable and versatile through-hole resistor used for a variety of applications. Its working principle is simple, yet effective, and its compact, cylindrical shape makes it easy to install in even the most cramped of spaces. It is rated up to a maximum power of 5 watts at 80°C, 5 watts at 55°C, or 10 watts at 40°C and is suitable for a variety of usage conditions.
