Through hole resistors have been used for many years due to their high reliability, excellent thermal performance and low cost.The H818KBDA application field and working principle is the same as other through hole resistors.The H818KBDA is a molded case resistor with high power dissipation, voltage rating, and surge handling capabilities. It has a rated power of 5W, rated voltage of 250V, and surge capability of 2000V. The resistor features a body made of encrusted mica or glass-ceramic for resistance to mechanical and environmental stresses.The resistor is designed to be used in applications requiring high accuracy and low noise such as power amplifiers and instrumentation.The working principle of a through-hole resistor is simple; it provides resistance by limiting the flow of current. The resistor is composed of a fixed length of wire, usually made of copper or chrome, which is wound around a ceramic core. The wire is wrapped in a ceramic material such as carbon, which increases the resistance. The final resistance value is determined by the length and diameter of the core, as well as the number of turns of the wire. The voltage rating of the resistor is determined by the total resistance of the wire and the maximum current that can be handled without damage.The H818KBDA features a wide range of tolerances which allows for improved performance and accuracy when compared to leaded styles of resistors. It also has a very low noise floor, which makes it ideal for applications that require extremely low levels of noise, such as medical equipment. Additionally, the resistor has a high surge capability, which makes it suitable for applications that require high inrush current such as lighting equipment.The H818KBDA also features a wide temperature range, which makes it suitable for operating in hostile environments, such as high temperature and vibration. Finally, it has a low inductance, which makes it suitable for applications where space is limited, such as high frequency circuits.In conclusion, the H818KBDA is a high performance, cost effective, and reliable through hole resistor. It is suitable for a wide range of electronic applications where precision, high surge capability, low noise, and reliable operation are essential. It is designed with a wide range of tolerances to meet the exact requirements of the application, and it has a wide temperature range and low inductance which make it an ideal choice for space constrained applications.
