Through Hole Resistors

A through hole resistor, like the HVR3700001243FR500, is a type of resistor that is used to create electrical resistance in an electric circuit. This type of resistor is typically housed in a cylindrically shaped, often heat-resistant enclosure that mounts into a circuit board. Through hole resistors are commonly used in applications requiring winding or high-precision resistive networks.The main components of a through hole resistor include the resistor element, solderable legs, and heat-dissipating mounting device. The resistor element will come in various types and sizes, depending on the application requirements. The position of the resistor legs will vary based on the specific model of the resistor element. The heat-dissipating mounting device is usually a ceramic or metal case that houses and protects the resistor element.

When it comes to the HVR3700001243FR500, it is a compression-style through hole resistor. This resistor\'s main body is a metal tube with two end caps that are sealed together by a spring. The resistor element is mounted within the metal tube, and it consists of a ceramic core with a layer of resistive material around it. The springs are positioned to push the resistive material around the ceramic core and the end caps together. This pressure creates the necessary resistance in the device.The HVR3700001243FR500\'s resistance values can range from 1.44 Ohm to 58.2 kOhm, depending on the specific model. The temperature coefficient of the resistor is +/-150ppm/°C, while the power dissipation ranges from 0.25W to 3W. Its operating temperature ranges from -55°C to 265°C, and its maximum overload voltage is 1500V. It also features a shock-proof design, making it ideal for use in harsh environments.

Additionally, the HVR3700001243FR500 is a non-inductive resistor. This means it does not introduce inductive impedance into the circuit. This makes it particularly useful for applications that require a low distortion or accurate signal, such as in medical imaging equipment, electric trains, and power trim systems. It is also useful in audio applications, as it can handle high power levels without introducing whistling or hum that can be caused by inductors.

In addition to its various applications and advantages, the HVR3700001243FR500 has high precision and low temperature coefficients. The resistor\'s mounting style ensures that the resistor is securely mounted to the board, eliminating the possibility of any loose wires or connections. It also offers superior protection against flashovers and short circuits. As such, the HVR3700001243FR500 is an ideal choice for projects that require high accuracy and reliability.
