Through Hole Resistors

Through hole resistors are electronic components with two terminals that provide either a static or dynamic resistance to increase or decrease the current flow based on the particular current and voltage applied. The resistance of an electrical component is measured in ohms, and these components are available in a wide range of values, from the milliohm to the gigaohm. Through hole resistors are often denoted by a three- or four-digit alphanumeric code, and they are often used to limit current flow or as part of a voltage divider circuit.One of the most commonly used through hole resistors is the H4665RBDA, which is a precision resistor designed for high-accuracy applications. The H4665RBDA is a trimmable resistor with a tight tolerance of 0.001%. This device is suitable for use in sensitive circuits and is a good choice for applications such as A/D and D/A converters, thermocouples, temperature sensors, and low-voltage power supplies. The H4665RBDA is available in five different versions, including a SMT type, and it can handle an operating temperature ranging from -30degC to +85degC. The low supply voltage of the device is 3.3V and its maximum power rating is 0.25W. The device is also RoHS compliant for compatibility with lead-free applications. The H4665RBDA offers excellent temperature coefficient of resistance (TCR) values of ±25ppm/°C and repeated temperature cycles up to ±7ppm/°C. It is also very stable under high temperature and has long-term drift of 0.3ppm/°C. The device has a low-noise figure and a wide resistance range, making it suitable for many applications. The working principle of the H4665RBDA is similar to other through hole resistors. When an alternating current is passed through the device, the dynamical resistance of the resistor varies according to the magnitude of current flow. This creates a voltage drop across the resistor, which is proportional to the current and the resistance value of the device. The device is constructed using a thin film overlayed on a ceramic base and two metallic strips that connects to the terminals.The H4665RBDA can be used in both analog and digital applications, including current monitoring, power conversion, level shifting, and temperature sensing. It is also suitable for use in precision data acquisition systems, including industrial and test equipment, medical instruments, and process control systems. This device is also suitable for use in high-performance audio applications, such as amplifiers, preamplifiers, and equalizers.In summary, the H4665RBDA is an excellent choice for precision applications requiring high accuracy, long-term stability, and low noise operation. Its wide range of applications include current monitoring, data acquisition, power conversion, and level shifting. Its tight tolerance of 0.001% and low temperature coefficient make it an ideal choice for accurate temperature sensing applications.
