Through Hole Resistors

A through hole resistor (also known as a through-hole, wire wound, or TH resistor) is an electronic component used in a wide variety of electronic designs and applications. Through hole resistors are usually constructed using a metal core with a metal film or metal oxide material wrapped around the core. The metal core and the film provide the necessary electrical resistance.

The most commonly used type of through-hole resistor is the carbon composition resistor. This type of resistor consists of non-conductive carbon particles that are mixed with a binder and placed between two metal leads. This type of resistor is very cost effective and reliable and can be used in a variety of circuits. They are typically used for basic circuit protection and to ensure that the voltage and current flowing on the circuit are within acceptable limits.

Wire wound resistors are more expensive than carbon composition resistors due to the complexity of their construction. This type of resistor requires winding a thin wire around a metal core. The resistive element of a wire wound resistor is the wire which creates a resistance due to its length, diameter, and material. Depending on the resistance and circuit application, this type of resistor may be chosen due to its larger wattage capability.

Metal oxide film resistors are used in applications where precision is required since they are highly stable. They can also handle higher wattage than a carbon composition resistor. They are constructed using a ceramic rod with a metal oxide coating. The thickness of the metal oxide coating determines the resistance.

CW01033R00JB12 Application Field and Working Principle

CW01033R00JB12 product is a 15 ohm through hole resistor, which is a single metal film resistor. It is not easy to produce a single metal film resistor, and has high tolerance and stability. This product is generally applied in devices requiring a high precision, such as a constant voltage source, an audio power amplifier, a logic circuit, measuring instrument, and oscilloscope. In addition, the application of this resistor is not only limited as a regular resistor, but also in many other occasions, such as a fuse, shunt protection, and trimmer.

The working principle of CW01033R00JB12 is based on Ohm’s Law and Joule-Lenz Law. Firstly, according to Ohm’s Law, the current flow (I) through the resistor is inversely proportional to its resistance (R). This means that for a certain fixed voltage (V) and fixed resistance (R), the current (I) will stay constant. Secondly, in order to dissipate the current, Joule-Lenz Law states that the power (P) loss is equal to the voltage (V) multiplied by the current (I). The resistance therefore dictates how much power the resistor can dissipate.

Moreover, parameters such as resistance, temperature coefficient, frequency coefficient, voltage coefficient, distortion coefficient, and inductance coefficient become extremely important when choosing a through hole resistor for a certain application. Temperature coefficient, as an example, is defined as the rate of change of the resistance as the temperature changes.

In general, CW01033R00JB12 is a cost effective and reliable through hole resistance with tolerance as high as 0.1%, which makes it suitable for various applications, such as audio power amplifier, logic circuits, measuring instrument, oscilloscope, and others. It is also able to handle higher power than a carbon composition resistor and provides an optimal combination of reliability and stability.
