Through Hole Resistors

A MFR2WSFTF52-348R through hole resistor is an electronic component designed to limit the flow of electricity in circuits. The resistance value of a through-hole resistor is determined by the size and material, and is typically inscribed on its body. Through holes, also known as plated-through-holes or PTH, refer to holes which are drilled into a printed circuit board (PCB). They are the connections between components and tracks, allowing current flow to be transmitted throughout the device and any other element it may be connected to.

The surface mount technology (SMT) also relies on soldering to connect components to the PCB. Through hole technology is typically used in large scale power and control circuits. Through hole components have some advantages over SMT components. Since hole resistors are physically larger, they can dissipate heat better and prevent burnt components and potential fire hazards. They are also robust and reliable, and can withstand mechanical strain and temperature changes better than the SMT equivalents.

The MFR2WSFTF52-348R through-hole resistor is a common type, featuring a metal-oxide layer that provides the resistor with its resistive properties. It is also designed to be highly durable, with an epoxy potting material that helps increase its ability to withstand extreme temperatures and humidity. The epoxy also acts as an insulation layer, further protecting the life of the component.

The standard operating temperature for MFR2WSFTF52-348R through hole resistors is -55 to 125°C, with a maximum resistance rate of 10%. Working current is 40SPMS (peak surge current). The working frequency is 0-200KHz, and the max voltage load is rated for 110 Vdc.

Some of the key application fields for MFR2WSFTF52-348R through hole resistors include automotive, consumer electronics, power supplies, medical products, and defence systems, amongst others. They can also be used in signal conditioning and signal transmission circuits.

The working principle of a through hole resistor relies on Ohm’s law, which states that the voltage across a resistor is directly proportional to the current flowing through it. The voltage is given by V=IR, and the resistance is calculated by Ohm’s Law as R=V/I. If the voltage and current is known, the resistance of the resistor can be determined.

In conclusion, the MFR2WSFTF52-348R through hole resistor is designed to limit electrical current in some of the most challenging environments, making them ideal for automotive and control applications. Thanks to their reliable and durable construction, through hole resistors represent a cost effective and reliable current control solution.
