Through Hole Resistors

Through hole resistors are a type of electrical component used for limiting electrical current. They are typically cylindrical in shape and consist of a ceramic-like material with a metal alloy coating. Through hole resistors are constructed so that they can be inserted into the printed circuit board, or PCB. This makes them ideal for electrical engineers in a variety of applications, particularly for applications that require complex board designs.

WW1FT3R48 Application Field and Working Principle

WW1FT3R48-type through hole resistors are a type of voltage-controlled resistors, usually used for DC signal selection, voltage division, voltage matching, current matching, and signal isolating applications. The resistors are designed to have a certain resistor value for a given voltage input. This is known as “non-linear” behavior as the resistors will have different shapes depending on the applied voltage.

The WW1FT3R48-type through hole resistors have a resistive film, usually composed of a three-way mixer of bi-tungsten silicide. This resistive film is placed on an alumina substrate. The resistive film thus acts as the resistor element and when a voltage is applied to this element, the resistance value is adjusted. The resistance value is controlled by the applied voltage, but the resistors are designed to have a certain inherent resistance, no matter what the applied voltage value is.

The WW1FT3R48 type of through hole resistors are used for a variety of applications such as voltage isolation, attenuation, protection, transient suppression, current regulation, protective isolation, matching, voltage division, and signal selection. The resistors are also useful in applications where high voltage is not desired but a low level signal is needed. In addition, these resistors are often used for switching operations as well as for controlling the direction of current flow.

These through hole resistors are designed to be highly reliable, tolerating steady-state temperatures up to +155 degrees Celsius. The resistors also have a good thermal stability and a low noise characteristic over a wide range of temperatures. The WW1FT3R48-type resistors have no hysterisis, no parasitics, and are free from static and ESD. As such, these resistors are often used in industrialized environments and for automotive applications.

In conclusion, the WW1FT3R48-type through hole resistors are a type of voltage-dependent resistors with a given inherent resistance. These resistors are designed to be highly reliable, can withstand high temperatures, and can be used in a variety of applications. The resistors are ideal for electronic engineers who require board designs that demand complex resistance values and allows for the control of current flow.
