The H421R5BZA is a through hole resistor and one of the most popular types of resistors in production today. It is a surface-mount device, meaning it is designed to be mounted on a flat, solid surface rather than a conventional PCB board. The H421R5BZA is characterized by its high precision and low temperature coefficient. It also has a wide temperature range and a wide operating voltage range, which makes it suitable for a variety of applications.The H421R5BZA is among the most popular through-hole resistors because of its superior performance and reliability. It has a low temperature coefficient, meaning its resistance doesn\'t change significantly over a wide temperature range. This makes it highly reliable and helps to ensure that there is minimal change in resistance due to temperature fluctuations.The H421R5BZA is also characterized by its wide operating voltage range. The operating voltage can range from 10 to 100 volts, making it suitable for use in a variety of applications. It also has a wide range of resistance values, from 1 to 10 megohms. This allows it to be used in a wide variety of circuit applications and enables designers to use it with a wide range of components.The H421R5BZA also has a relatively low power consumption and dissipates its heat relatively well. This makes it highly efficient and ensures that it can be used in high-speed applications without overheating. Additionally, it is relatively inexpensive and easy to manufacture, making it a popular choice for many electronic designs.The H421R5BZA is most commonly used in applications where high precision and low temperature coefficients are required. It is particularly popular in automotive and medical applications due to its excellent performance and reliability. It is also commonly used in computing, telecommunications, and power supply applications.The working principle of the H421R5BZA is relatively simple: it is a resistor composed of a fixed number of turns and a sleeve-shaped coil of wire that grows in diameter with increasing current. When current passes through the resistor, electrons encounter resistance as they travel through the coil and the changing diameter of the coil creates a resistance that built as the coil expands. This resistance is known as "dynamic resistance" and is used to regulate electrical current and voltage.The H421R5BZA is capable of extremely precise resistance levels and low temperature coefficients due to its unique structure. It is resistant to shock and vibration, making it suitable for use in harsh environments. Additionally, it is relatively small, making it ideal for use in compact designs.The H421R5BZA has a wide range of applications and is used in a variety of industries including automotive, medical, telecommunications, computing, and power supply. It is highly reliable and durable, making it one of the most popular through-hole resistors used today. Its wide operating voltage range and low temperature coefficient make it suitable for many applications where high precision and low temperature coefficients are required.
