Through Hole Resistors

Through hole resistors are resistors that are mounted in a through-hole on a printed circuit board. The through hole allows the resistor to be soldered into place, ensuring that it will remain securely connected. Through hole resistors are typically used in circuits that require a reliable electrical connection, are too large to be produced with a surface-mount resistor, or need to be protected from mechanical and/or environmental stress. These resistors are also commonly used in projects that involve complex connecting of circuit elements.

RWR81S42R1FRS73 Application Field and Working Principle

The RWR81S42R1FRS73 through hole resistor is a general purpose resistor with a power rating of 0.25 watts. It is ideal for applications that require an accurate and reliable resistance such as high-temperature sensors, switchboards, or warning systems. This particular type of through hole resistor has a wide frequency range of up to 1 MHz and a secure interwoven lead construction, making it compatible with multiple terminals.

The working principle of this resistor is based on Ohm\'s Law, which states that the current passing through a conductor is directly proportional to the potential difference between the two points. This is related to resistors because the current passing through the resistor is inversely proportional to the resistance between the two points; therefore, the greater the resistance, the lower the current.

In the case of the RWR81S42R1FRS77, the actual resistance of the resistor is determined by the formula, Resistance = Power / Voltage ^2, which can be used to determine the precise resistance for the application. This is useful because it allows users to accurately adjust the resistance of their circuit in order to meet their needs.

These through hole resistors have a wide variety of application fields, and are commonly used in voltage dividers, current limiters, regulators, signal-level attenuators, and level-shifters. They are also ideal for surge-current protection, voltage-stabilization, automotive applications, and motion control systems.

Overall, the RWR81S42R1FRS77 through hole resistor is a reliable and accurate solution for many different types of applications. They can provide precise and secure resistance, allowing users to adjust the resistance of their circuits as needed. In addition, the interwoven leads offer a secure connection while the wide frequency range makes it compatible with multiple terminals.
