Through Hole Resistors

Through hole resistors are a type of resistive component that are characterized by a metal body with two or four terminals which allow them to be inserted through a hole in a circuit board. They are typically used in applications which require a highly accurate and reliable electrical resistance value.The RN55E70R0BB14 is a through-hole resistor developed by The Bosch Group which is designed for a variety of application fields. This resistor is used mainly in automotive, industrial, and consumer applications such as engine control, white goods, home appliances, telecommunications, and LCD/LED displays.

RN55E70R0BB14 Application Field and Working Principle

The RN55E70R0BB14 is a high-powered through-hole resistor designed for use in a wide range of applications. It is constructed with a non-inductive wound construction and is capable of delivering a high current with a very low typical ohmic value of 0.1 ohm. The resistor features a low thermal resistance of 0.5 K/W and a wide temperature range of -55 to +175°C.The RN55E70R0BB14 is primarily used in automotive, industrial, and consumer applications to provide a highly accurate and reliable resistance value without the risk of thermal runaway. The resistor’s low thermal resistance allows it to dissipate heat from the system within a short time, preventing system overloads and increasing system reliability.The resistor’s high power rating allows it to handle large amounts of power without overloading the circuit or affecting the performance of the system. The resistor’s low resistance value enables it to be used in applications where a higher resistance value would reduce the system’s current rating. The resistor’s low surface mount height also makes it suitable for a variety of circuit board layouts.The working principle of the RN55E70R0BB14 follows the basic principle of resistance. When a voltage is applied across the resistor, an electrical current flows through the resistor in proportion to the applied voltage. This current-voltage relationship is resistive in nature and is governed by Ohm’s Law.The resistor’s resistance to current flow is determined by the material it is made from. The RN55E70R0BB14 is constructed with a non-inductive wound construction which is made from a combination of carbon and other materials, creating a resistive element which has a much higher resistance per unit length and temperature coefficient compared to other types of resistors. This makes the RN55E70R0BB14 an excellent choice for applications that require a highly accurate and reliable resistor.The RN55E70R0BB14 is also designed to be compatible with a variety of circuit board layouts. The resistor features two or four terminals on the end which allow it to be inserted through a hole in a circuit board in order to provide a highly consistent contact connection. The resistor’s small size also makes it suitable for use in tight spaces.
