The through hole resistors are used to control the current in a circuit with the help of a resistance system. They are commonly used in a variety of applications such as motor controllers, power supplies, emergency lighting, and other power circuits. In this article, we will discuss the YR1B21RCC application field and working principle.

The YR1B21RCC is a ceramic encapsulated, low-temperature, non-illuminating variable-resistor type. This type of resistor is also known as a through-hole resistor. It has a mounting and contact point on two terminals that go through the circuit board. This is known as through-hole mounting because it goes through the PCB\'s holes.

This type of resistor is typically used as a back-up for expensive and bulky adjustable resistors. It is therefore widely used in applications where space is of great importance. For instance, most of today\'s electronic devices are designed with small circuit boards and space limitations and require smaller components, such as through-hole resistors.

The YR1B21RCC has a range of resistances from 0.5 ohms to 10 kohms and provides a high level of accuracy. It also features a short working time of no more than 0.5 seconds. Furthermore, this type of resistor has low thermal resistance allowing it to maintain its electrical characteristics at high temperatures.

In terms of its working principle, the YR1B21RCC is based on a thermal principle, meaning that the resistance value is changed by varying the thermal resistance between two plates. This type of resistor works when a voltage or current is applied to one of the plates, causing it to heat up. This heat is then transferred to the adjacent plate without electrical resistance, resulting in a temperature change between the two plates. The result of this is a change in the electrical resistance between the two plates depending on the amount of heat generated.

The many features and advantages of the YR1B21RCC through hole resistors make them a great choice for many applications. This type of resistor is highly durable and precise, and is suitable for use in both high and low temperatures. Furthermore, with its reduced size and low cost compared to other types of resistors, it provides an ideal solution for many applications that require accurate and reliable results.

To sum up, the YR1B21RCC through hole resistor is a highly reliable and precisely accurate type of variable resistor. It features a short working time, a range of resistances from 0.5 ohms to 10 kohms, and a low thermal resistance. This makes it a great choice for applications that require smaller components with high accuracy and reliability. As such, it has become a popular option for many applications, such as motor controllers, power supplies, emergency lighting, and other power circuits.
