Through Hole ResistorsCB2JB4R30 is a through-hole resistor. It is suitable for use in high frequency and high quantity applications where maximum efficiency of power dissipation and electrical performance are required. This type of resistor is well suited for precision control in power amplifiers and other applications which require high current travel times.The CB2JB4R30 is constructed of an aluminium ring frame, a ceramic core, and a metal film coating. The ceramic core is used to provide thermal stability and uniform electrical performance, while the metal film coating is used to provide resistance to moisture and other atmospheric conditions.The CB2JB4R30 is a two-layer, through-hole resistor. The external layer is typically a metal film, while the internal layer is a vacuum deposited, oxide-laden silicon layer. This two-layer construction helps to ensure that the temperature-sensing device will work reliably in high temperature environments.In terms of its applications, the CB2JB4R30 can be used in precision control systems, musical instruments, and other electronics. It can be used in the production of vacuum sensors and in the construction of adjustable frequency filters. It is also suitable for use in the automotive industry and industrial applications.The CB2JB4R30 is operated using direct current (DC) and alternating current (AC). The operating voltage range is between 0 – 14V, with a maximum working current of 6A. When operating the CB2JB4R30, it is important to keep the temperature between 20 and 30°C to ensure optimal performance.The working principle behind the CB2JB4R30 is based on the basic characteristics of resistors: electrical current is generated when a voltage is applied across two terminals, and the current passing through the resistor generates heat. The heat is then absorbed by the ceramic core and dissipated by the metal film coating. This dissipated heat is then monitored by temperature sensors, allowing the resistance of the resistor to be accurately adjusted.One of the key benefits of the CB2JB4R30 is its low thermal resistance. This low thermal resistance allows it to efficiently dissipate heat, and to quickly cool down when the circuit is turned off. This efficient cooling helps to protect the internal components of the circuit from overheating and damage.Overall, the CB2JB4R30 is a reliable, efficient, and versatile through-hole resistor that is suitable for a wide range of applications. Its low thermal resistance and tight temperature control make it particularly suitable for precision control systems. It is also durable and reliable enough to be used in high temperature environments.
