Through Hole Resistors are a type of resistors designed to sit in the holes in a PCB to provide and regulate the electric current traveling through the circuit. The H4191KBZA is a popular through hole resistor that can be used in various applications, both military and civilian. In this article, we will discuss the various applications and principles of this resistor.

Applications

The H4191KBZA can be used in many applications, but it is mainly used for high frequency and voltage applications. It can be used in military-spec applications, such as radio and communications equipment. It can also be used in more common applications, such as power supplies and protection circuits. It can also be used for precision instrumentation.

The H4191KBZA can be used in audio applications, such as amplifiers and audio receivers. It is also commonly used in measurement and control devices such as signal processors. It is suitable for use in both industrial and consumer electronics.

Working Principle

The H4191KBZA is a through-hole resistor, which means it is designed to be inserted into the holes in a PCB. It is made up of three parts - a resistor body, a ceramic insulating coating and a pair of terminals. The resistor body is made of alumina or a nickel chromium alloy. It is resistant to high temperatures and can withstand up to 1000˚C.

The ceramic coating is used to prevent electricity from passing around the resistor body. This prevents possible short circuits and ensures that the correct current is used in the circuit. The ceramic coating also helps to dissipate heat. The terminals on the H4191KBZA are made of silver-plated copper and are designed to fit securely into the holes in the PCB.

The H4191KBZA works by creating a small voltage drop across the resistor body. This voltage drop is used to regulate the current flow in the circuit. The amount of voltage drop is determined by the value of the resistor, which is measured in ohms. The value of the resistor is determined by the resistance of the resistor body.

The H4191KBZA is a reliable and durable resistor that can be used in a variety of applications. It has a wide range of resistances available, which allows it to be used in many different types of circuits. It is also resistant to heat, making it suitable for use in high temperature applications.
