Through Hole Resistors: YR1B17K8CC Application Field and Working Principle

Through hole resistors are electrical components consisting of a conducting material, usually resistance wire or thin film, situated between two terminal ends, which are mounted on a circuit board. Through hole resistors are typically used in circuits where low voltage and low current levels are needed for applications such as signaling, switches, and current-limited power supplies.

An example of a through hole resistor, the YR1B17K8CC, is a radial-style leaded resistor with a surface mountable body. It offers a wide range of resistance values from 0.1 ohms up to 10M Ohms. Its operating temperature range is from –55°C to +125°C. Its primary application field is in communications and consumer electronics.

Working Principle:

Through hole resistors work on the premise of Ohm’s Law, which states that the resistance, R, between two points in a conductor is related to the voltage, V, and the current, I, as follows: R = V/I.

Resistor applications usually involve the control of current or voltage in a circuit. By applying Ohm\'s Law, current can be limited in a circuit by increasing the amount of resistance to reduce the amount of current flowing through the circuit. Conversely, if the amount of resistance in a circuit is reduced, the current will be increased.

In the case of the YR1B17K8CC, the value of the resistor is directly related to the voltage and current that it is being exposed to: The higher the voltage and current put across the resistor, the greater the amount of resistance which it offers. This is achieved by creating a loop of metallic material such as resistance wire or film, the area and length of which directly influence the amount of resistance offered by the resistor. The longer and narrower the loop, the greater the amount of resistance, and vice versa.

Design and Construction:

A through hole resistor typically consists of three components: a conductor, two terminals and an insulating layer, all housed within a non-conductive housing. The conductor can be made of resistance wire, thin film, or other conducting material, which is wound in a set pattern to create the desired resistance. The terminals are typically made of metal and are welded to the two ends of the resistor, while the insulating layer serves to protect the resistor from potential short circuits or damaging external conditions.

The YR1B17K8CC has a resistive element made from a low-tolerance carbon film and is encased in a glass-filled epoxy package. The packaging is designed to provide excellent heat transfer, as well as environmental protection, and ensures that the resistor runs cool, even during high power operation.

Applications:

Through hole resistors are used in a wide array of applications, such as audio equipment, DC/DC power regulators, motor drives, security systems, signal routing, surge protection devices, and HVAC systems. The YR1B17K8CC is particularly well-suited for use in low-power, high-impedance line drivers, in which low voltage and current levels are needed.

In addition, the YR1B17K8CC can also be used in a variety of consumer electronics applications, such as HD televisions, digital video recorders, DVD players, gaming systems, and more. Due to its low power requirements, it is ideal for use in applications where energy efficiency is a priority.

Conclusion:

Through hole resistors, such as the YR1B17K8CC, are versatile components used in a wide array of applications. From audio equipment and DC/DC regulators to consumer electronics, they can be used wherever low levels of voltage and current are required. The YR1B17K8CC has an extended operational temperature range, making it suitable for use in a variety of settings, and its epoxy package ensures excellent heat control and environmental protection. Overall, the YR1B17K8CC is a proven through hole resistor for a variety of electronics applications.
