Through Hole Resistors are passive electronic components used to restrict the flow of electricity in a circuit. The SQP700JB-0R47 is a type of through hole resistor that plays an important role in many electronic devices’ circuits. This article discusses the application field and working principle of the SQP700JB-0R47.

The SQP700JB-0R47 is a wirewound through hole resistor, known for its ability to withstand high currents. It is made with manganin wire, which is a copper-manganese-nickel alloy. This combination allows for a higher tolerance to temperature changes, which makes it a great choice for the construction of high-end electrical systems, such as power supplies and military electronic devices. It can handle high amounts of power due to having a much higher wattage rating than other types of resistors, ranging from 1 watt to 5 watts. The SQP700JB-0R47 is also used in higher frequency applications, such as RF abatement, noise filtering, and signal isolation.

The working principle of the SQP700JB-0R47 is quite simple. It is designed to measure resistance by connecting two points. As current flows through the wire, some of it is lost, creating resistance. This creates a voltage drop, a decrease in voltage between two points due to resistance in a circuit. This voltage drop is then measured to determine the resistance at a given point. This is known as Ohm’s Law, which states that the voltage (V) is proportional to the current (I) multiplied by the resistance (R). By measuring the voltage and current, the resistance can be calculated.

The SQP700JB-0R47 is an important component in many electronic devices due to its ability to handle high amounts of power and work effectively at higher frequencies. It is an ideal choice for systems that need reliable and accurate control of current in order to operate correctly. The combination of manganin wire and its high wattage rating allows for greater control of power in applications that require precise measurements.
