Through Hole Resistors

Through Hole Resistors, also known as leaded resistors, are resistors that are mounted through a hole drilled on printed circuit boards (PCBs). They come in various types, including carbon film, metal oxide film, and metal film resistors.

The UB5C-3R3F2 is a type of through-hole resistor that consists of a ceramic body encased in an alloy-clad metal case and a wire leads. Typical applications for UB5C-3R3F2 through hole resistors include high frequency EMI filtering, power supplies, circuit protection, and application-specific circuits such as audio equipment. In order to properly use a resistor in a circuit, one must first understand its working principle.

The UB5C-3R3F2’s basic working principle is that of a voltage divider. In a circuit, two resistors of different values are connected in series between two voltage sources. As a result, the higher-valued resistor dissipates more power than the lower-valued one, and, in turn, fewer volts will be dropped across it. This can be demonstrated by connecting a UB5C-3R3F2 as a voltage divider between two voltage sources.

When the UB5C-3R3F2 is used as a voltage divider, the voltage at the midpoint of the divider (where the two resistors are connected) is affected by the relationship between the resistances of both components. The voltage at the midpoint can be calculated by dividing the voltage at each resistor by the respective resistance value. The resulting voltage at the midpoint will be lower than the voltage of either of the two resistors.

Besides being used as a voltage divider, the UB5C-3R3F2 resistor can also be used to limit current in a circuit. When it is used in a circuit, the resistor dissipates power. This means that, as more current flows through the circuit, the resistor’s resistance increases, leading to a decrease in the amount of current that can flow through the circuit. This allows the UB5C-3R3F2 to limit current in the circuit and prevent it from becoming overloaded.

Another use of the UB5C-3R3F2 resistor is as an overvoltage and undervoltage protector. When it is used in this application, the resistor is connected in series to a voltage source. The voltage at the midpoint of the divider is monitored, and if it falls below or rises above a certain threshold, the resistor will automatically switch off the voltage source.

Finally, the UB5C-3R3F2 resistor can also be used for circuit protection. In this case, the resistor is connected in series to a sensitive circuit, and any increase or decrease in the voltage across the resistor will automatically switch off the sensitive circuit.

In summary, the UB5C-3R3F2 resistor is a type of through hole resistor that is commonly used for a variety of applications, including high frequency EMI filtering, power supplies, circuit protection, and even voltage divider and overvoltage/undervoltage protection. Its working principle is based on the relationship between the resistances of two components connected in series, which results in a voltage drop at the midpoint between the two components.
