Through Hole Resistors

B12J2K5E Application Field and Working Principle

B12J2K5E is a through hole resistor type that is widely used in electronics. Through hole resistors are resistors that are encased in a cylinder-shaped body, usually made from ceramic, plastic, or other insulating material. These resistors usually have two or more terminals, though single-terminal resistors are also available. B12J2K5E resistors are further characterised by their small size and their ability to withstand high temperatures.

The B12J2K5E is typically used in applications where they are required to handle a wide range of temperatures. Examples of these include automotive, power inverters, motor control, and telecommunications applications. Because of its compact size and temperature range, this type of resistor is particularly useful in situations where space is limited and environmental conditions fluctuate. The B12J2K5E type relies on its ceramic body to provide good insulation and help reduce its temperature coefficient.

In terms of its working principle, the B12J2K5E works by applying resistance to a circuit. This reduces the amount of current that can flow through the circuit, and consequently, the amount of electrical energy available for use in the circuit. The size of the resistor determines the percentage of current that it is able to reduce, whilst the material that it is constructed from helps provide additional temperature-resistant protection.

The B12J2K5E is also characterised by certain construction features which allow it to operate effectively. These include its small size and thin leads. The two leads, or "spikes", that are used to provide electrical connectivity, help to reduce the voltage drop across the resistor and improve the efficiency of the resistor. The thin shape of the leads also allows for greater surface area, helping to spread heat and ensure that the resistor is able to handle higher peak current without overheating.

The B12J2K5E is part of a range of through-hole resistor types. There are many different types of resistors available, with varying characteristics and specifications to match different applications. However, the B12J2K5E is a popular choice, due to its small size, temperature range, and construction features, all of which contribute to making it a reliable and cost effective through-hole resistor.
