Through Hole Resistors

Through hole resistors are an essential component of virtually every electrical device. These components are used to control current flow, limit voltage, and provide protection and stability to circuits. Often referred to as “THR”, these components are found in almost every electrical device from radios and televisions to cell phones and computers.The RSF3WSJR-73-1M is a type of through hole resistor. It is a three-watt, surface mounted resistor with a voltage rating of 73 volts and an individual resistance of 1 Megohm. It uses a thick-film, chip resistive element. This element is made up of fine conductive particles that are applied to the surface of the resistor and then treated with an insulating material.Through hole resistors are applied to a printed circuit board (PCB) by being inserted into plated through holes. The process of soldering these components to boards is very important since it can affect the reliability and accuracy of a circuit. The process typically requires soldering a wire or a thread into the plated through hole, then clipping the component’s legs and inserting it into the hole. Heat is then applied to melt the solder and secure the component.The RSF3WSJR-73-1M has a current rating of 0.16 mA, can dissipate a maximum power of 3 watts, and operate at a fixed junction temperature of +150°C (most resistors cannot handle this temperature). Its resistance range is from 1 MΩ to 22 MΩ and its tolerance is at 5%.The RSF3WSJR-73-1M is used for many applications such as voltage regulation, current-limiting, oscillator circuits, line matching, and more. It is especially useful in applications that require precise control of the current or voltage.The working principle of through hole resistors is based on Ohm’s law, which states that the current flowing through a metallic conductor is directly proportional to the potential difference (voltage) applied across its ends. By placing a resistor in the circuit, the current will be lowered accordingly. The magnitude of the current is inversely proportional to the resistance of the resistor, so, the higher the resistance value, the lower the current.Through hole resistors are a very reliable and durable component, and are widely used in many different devices and applications. The RSF3WSJR-73-1M is a unique component that is designed to withstand higher temperatures while offering a precise level of voltage and current regulation. As a result, it is an ideal option for various complex circuits and applications.
