Through Hole Resistors: RLR20C7502GRRSL Application Field and Working Principle

Through hole resistors, or known as through-board resistors, are an electronic component used in printed circuit boards (PCBs) when a resistor needs to be placed directly onto the printed circuit board and securely mounted. Through hole resistors are very common in applications such as automotive electronics, temperature control, power management, and data acquisition. One type of through hole resistor that is often used in these applications is the RLR20C7502GRRSL.

The RLR20C7502GRRSL is a Milwaukee-based, axial-leaded, carbon home resistor that is 5/8” tall and features a black body and white code bands. Its rated power is 0.2W at 70°C, and its composition is carbon film with a PPS core and silicon rubber coating. The resistor offers a resistance range within 50 ohms to 750,000 ohms, and a tolerance tolerance of ±2%. The RLR20C7502GRRSL is able to perform in challenging environments with temperatures ranging from -55°C to 155°C (-67°F to 311°F). Additionally, the resistor is RoHS compliant, so it can be used for a variety of industry applications.

The RLR20C7502GRRSL works by selecting resistors based on the specifications of the particular application. The specified voltage and power range of the resistor are matched to those of the PCB. The leads of the resistor are then threaded through pre-drilled holes on the PCB and soldered in place. Once the resistor is in place on the PCB, it acts as a variable resistance to limit the current flow between two points. This is beneficial for voltage regulation, over-current protection, signal conditioning, impedance matching, and other related applications.

Overall, the RLR20C7502GRRSL through hole resistor provides a cost effective and reliable solution in a variety of electrical and electronic equipment applications. As a durable and dependable component, it is well-suited for environments that require high temperatures or harsh conditions, as well as general through hole printing. Furthermore, its size makes it suitable for projects with limited space requirements. With all these benefits, the RLR20C7502GRRSL can provide an effective voltage or current limiting solution to many projects.
