Through Hole Resistors

Through-hole resistors, also known as leaded resistors, are the most traditional type of resistors. They can play an important role in a circuit, acting as a current limiting device, temperature compensation, and noise reduction. This article will outline the application field and working principle of the through-hole resistors of part number RN65D38R3FRSL.A through-hole resistor can be used in a variety of areas. It is mainly used in precision circuitry as it can absorb signficant amounts of power and is not prone to overheating or experiencing a sudden electrical breakdown. It is also used in automotive repair and circuit design, as it is resilient in extreme temperatures up to 120 degrees Celsius/225 degrees Fahrenheit and can withstand high altitudes while still performing. Because they have a high power rating and can comform to numerous standardized packages, through-hole resistors are preferred over other types of resistors such as SMD (Surface Mount Devices). The part number RN65D38R3FRSL is an axial-leaded through-hole resistor with a tolerance rating of ±0.25%. It has a power (or wattage) rating of 0.125W, a Dielectric Withstand working voltage of 500VDC, and a resistance value of 3.3 Ω. It is an inexpensive, versatile resistor, which makes it suitable for many applications.When a voltage is applied across the leads of the through-hole resistors, a current I flows through it. This current is proportional to the voltage V, according to Ohm\'s Law, which states that I = V/R, where R is the resistance value. The resistor will dissipate an amount of power equal to the product of the voltage and the current, and is known as the Joule effect, or P = V2/R. The resistor will convert this power to heat, which is why heat-sinks and thermal protection are necessary to prevent failure. In addition to its power rating and its resistance value, the resistance of the through-hole resistor can also vary with temperature. This is known as the PTC (Positive Temperature Coefficient) or NTC (Negative Temperature Coefficient) effect. For RN65D38R3FRSL, the NTC effect is greater than the PTC effect, meaning that its resistance will decrease with increasing temperature. This can be used to maintain stability in circuits that are exposed to changing temperatures. Through-hole resistors are among the most common and widely used electronic components. Their use is strongly rooted in electrical engineering, providing a reliable connection between components for various applications. With their easy installation and reliable performance, through-hole resistors can provide an inexpensive solution for needs such as noise-reduction, current-limiting, and temperature compensation.
