Through Hole Resistors

A through hole resistor is a type of resistor which is designed for mounting through a hole on a printed circuit board (PCB). Generally, these resistors are prefixed with the letter “H” to indicate their hole mounted nature, such as the H843RFCA resistance element. These components are available in a variety of values and are made from materials such as metal film, carbon composition, ceramic, and others.

H843RFCA application field and working principle

The H843RFCA through hole resistor is a general-purpose device that is used in a variety of applications, such as automotive, audio, communications, and instrumentation. It is most often employed as a resistive element in electronic circuits, where its low-tolerance and high-temperature stability make it an ideal choice. The construction materials of the H843RFCA provide a low temperature coefficient and excellent electrical performance.

The H843RFCA is a through hole resistor that is designed for mounting through a hole on a printed circuit board (PCB). Its working principle is quite simple: when current passes through the resistor, it produces a proportional amount of electrical resistance. In other words, as the current increases, so too does the resistance. This is the key property of a resistor as it allows us to control and regulate the amount of current passing through the circuit. Thus, the H843RFCA can be used to regulate the power supply in a wide range of electronic devices.

The H843RFCA is constructed with a ceramic core and metal film layers. The ceramic core provides excellent thermal stability and helps to reduce noise from the resistor. The metal films provide superior mechanical and electrical stability, as well as excellent thermal capacity and high temperature cycling. The metal films also act as a moisture barrier, ensuring the H843RFCA’s long-term reliability.

The H843RFCA resistor is available in a wide range of resistance values, ranging from 1,000 ohms up to 1,000,000 ohms. It also has a low tolerance value of 0.5%. This guarantees that each resistor has a resistance value within the specified range, ensuring reliable performance. In addition, the H843RFCA has a high temperature rating of +150°C and can withstand a voltage of up to 250 volts.

In addition to its wide range of resistance values, the H843RFCA can also be used as a temperature sensor. By attaching the sensor to an electronic circuit, it can detect changes in temperature, enabling accurate temperature sensing. This is especially useful in automotive, medical, and industrial applications where accurate temperature control is essential.

Overall, the H843RFCA through-hole resistor is an extremely flexible device. It can be used in a variety of applications, from automotive to industrial, and its excellent temperature and voltage ratings make it suitable for a range of tough environments. It is available in a wide range of resistance values and offers excellent stability and reliability. Thus, it is an ideal choice for any electronic circuit.
