Chassis Mount ResistorsChassis mount resistors are widely used components in the electronics industry. They are designed to be mounted directly onto circuit boards or chassis in order to dissipate heat and provide electrical protection. The RER70F1581RCSL (RER70F1581) is a type of chassis mount resistor, designed for high power applications.The RER70F1581 is a high power, low profile, dual-in-line, chassis mount resistor. It offers excellent performance in applications requiring both high power dissipations and flexibility. It is ideal for providing power distribution, ground isolation, and current sensing in high power systems. It has a wide operating temperature range (-55°C to +200°C) and is designed for direct mounting to most common chassis and circuit board materials.The RER70F1581 features high isolation resistance, low contact resistance, and high thermal conductivity. It is designed for use in a wide range of applications, such as: motor drives, automotive, power supplies, consumer electronics, computers and telecommunications. Its operational characteristics make it ideal for providing reliable power distribution and short circuit protection.The RER70F1581 is designed with a two-part construction. The upper part is a polyamide base with an integral aluminum shell and adjustable clamping screws. The lower part is a mica-based resistor body. The two parts are hermetically sealed, and all contact surfaces are treated with a corrosion-resistant coating, ensuring your resistor will stay mounted and be able to withstand even the harshest environments.The working principle of the RER70F1581 is based on the principle of variable resistance. The resistor body is made up of mica, a highly conductive material. When a voltage is applied to the resistor, the mica breaks down, resulting in a decrease in resistance. This allows you to control the amount of current flowing through the resistor, thus providing power distribution and short circuit protection.The RER70F1581 is designed to provide reliable performance in a variety of environments. It is mechanically rugged, with a heat dissipating frame and adjustable wires to enable mounting to any chassis or circuit board material. It is also corrosion-resistant, with the contact surfaces shielded from any adverse environmental effects. The high power dissipation capability ensures it will be able to withstand even the harshest conditions.The RER70F1581 provides great performance in high-power applications. Its wide temperature range makes it suitable for a variety of applications, and its two-part construction ensures reliability and flexibility. The adjustable contact screws enable it to be securely mounted to almost any chassis or circuit board material. Overall, the RER70F1581 is an ideal component for engineers looking for a reliable and flexible chassis mount resistor. Its high power dissipating ability, wide temperature range, and two-part construction make it an essential element for any high power system. Whether you need to provide power distribution, ground isolation, short circuit protection, or current sensing, the RER70F1581 is the perfect component for the job.
