Through Hole ResistorsThrough Hole Resistors (THRs) are an essential type of electronic component used for impedance control and electrical energy distribution in many circuits. They are comprised of two small metal rods that extend into a hole drilled into a circuit board. The rods have a specific diameter, wicking, and resistance value, and are connected to a terminal for connection to other components in the circuit.Typically, THRs are used to provide impedance and control circuit frequency. Impedance is the measure of the opposition that a circuit presents to energy routing and frequency, and can have a major impact on the electrical behavior of the circuit. When impedance is too high or too low, it can result in malfunction of the circuit. Resistors help to control impedance by reducing the passage of current along a certain point in the circuit, thereby allowing for more energy to flow through other points of the circuit.THRs are not only used to control impedance, but also to shape the transmission of voltage signals. By adding a series of resistors to a circuit, the voltage of a signal can be reduced or raised, depending on resistance value. This ability to shape voltage signals is especially important in audio applications, where the transmission of certain music frequencies must be controlled in order to achieve desired sound. In addition to satisfying audio applications, THRs are used by engineers to provide power to various circuits and to control the rate of charge for batteries.Furthermore, the working principle of a THR is relatively simple. When exposed to electric current, the resistance material in the THR resists the flow of the current, creating a voltage drop. This voltage drop can be used to control the current flow and voltage, providing a known stable voltage to the other circuits.Not all THR’s are created equal – they come in a variety of sizes and levels of resistance for applications that require different levels of control. For example, the UB5C-9R1F1 is a THR created specifically for controlling higher current with low profile applications. This THR has a low resistance rating of 1R1 (1 ohm) and is designed to provide a higher current capacity and improved frequency response along with its smaller package size. Additionally, its robust design helps to protect against electro-magnetic interference, enabling reliable performance across a wide range of applications.In summary, Through Hole Resistors are a vital component in many electronic circuits, providing impedance control, voltage signal shaping, and power distribution. Their functionality is based on simple principles – the resistance material in the THR resists electric current allowing for voltage drops to be used to control current and voltage flow. The UB5C-9R1F1 THR is a unique THR built for higher current control with low profile applications. With its low resistance rating and robust design, this THR brings reliability and performance to many applications.
