Through Hole Resistors

Through-hole resistors, also known as leaded resistors, are the oldest form of resistor and are still being used today. They have been utilized for decades in virtually every circuit and are the most consistent and reliable types of resistors. Lead Resistors are typically made from metal or ceramic and are designed to have a hollow cylindrical body where the two terminals or leads extend from both ends. The resistor is placed into the board with its leads soldered to the circuit which allows it to remain in place.

RN55C2152BRSL Application Field and Working Principle

The RN55C2152BRSL is a surface mount resistor and is constructed from a metal alloy, typically either copper, manganese, or a combination of other elements. This type of resistor is an integral component in many electronics and can be found in power circuits, audio amplifiers, home appliances, and industrial equipment. A key feature of the RN55C2152BRSL is that it is exceptionally small which is useful for when space is at a premium on a device.

This resistor utilizes a \'thick-film\' construction where a layer of resistive material, usually ruthenium oxide, is applied to the metal substrate along with valuable metal elements which serves to increase the tolerance and reliability. This layer is created through screen-printing a paste-like solution onto the substrate and then sintering it at high temperatures, a process which can also add a protective finish to the component. After sintering, the finished result is a metal-oxide resistor with a precisely controlled resistance.

The most widely used form of thick-film resistor is the 1206 chip style, which is represented by its size designation. The 1206 signifies a 12mm x 6mm surface mount package, but despite pictures of this resistor appearing small, it can still have some impressive power levels with thermal tolerances of up to >350°C. The most common power rating of the 1206 size is 0.125W (125mW) and is normally used in low-power circuits, whereas the higher-powered 0.5W (500mW) version tends to be reserved for use in high power amplifiers.

Surface mount resistors are ideal for densely populated boards and have many advantages compared to traditional through-hole mounting. The leadless design allows a more compact assembly and it does not have to rely on the strength of the solder joints, which should remain intact throughout shock and vibration. Additionally, the already established high resistance to thermal shock makes it suitable for use in thermally demanding applications.

The RN55C2152BRSL has a nominal resistance of 1.5KΩ and a power rating of 0.125W, but other values and variations of this resistor are available including higher power variance, as well as differing tolerances and temperature coefficients. The resistor is also more cost effective than through-hole style resistors, due to its more compact design and mass-production capabilities.
