HSA1022RJ

Chassis Mount Resistors

Resistors are fundamental electronic components that can be used to regulate voltage in a circuit. In a chassis mounted resistor, the resistor is securely attached to the circuit board or printed circuit board (PCB). The chassis mounted resistor is typically a cylindrical component with pins that extend out from either side. The resistor is usually mounted directly into a chassis or enclosure.

HSA1022RJ is a laminated resistor with a power rating of 5 Watts, constructed from ceramic material with a resistance rating ranging from 0.5 ohms to 4.2 kilo-ohms. This resistor is contact-cooled, features a lead wire connection, is sealed with epoxy resin, and is designed to remain dust-free when used in conjunction with a compatible dust cover. The primary application of this resistor is in power supply and power management circuits.

Working Principle

The HSA1022RJ operates through thermal protection, which works by limiting the amount of current that can flow through the resistor. Thermal protection is a built-in feature of resistors that can be triggered when the resistor overheats due to excessive current. When the resistor gets too hot, the thermal protection shuts the circuit down until the thermal overload is reset. This type of resistor is ideal for regulating power levels and for protecting circuitry from potential damage.

When the resistor is properly mounted, standard size mounting holes and tapped holes in the chassis are used to firmly hold it in place. The terminals are soldered to the board and the leads are crimped for better electrical contact. It is important to ensure that the leads are securely mounted in order to prevent contact failure and electrical arcing. This is especially important for high power applications such as those found in switch mode power supplies.

Benefits

HSA1022RJ chassis mount resistors offer several advantages over other types of resistors. These include reliable electrical contact, a high power handling capacity, and excellent thermal performance. Due to their convenient mounting, these resistors are easily installed and do not require additional components or wiring for their installation. They also provide superior moisture and dust protection, making them ideal for applications where the environment is harsh or the internal components may be exposed to liquid.

The HSA1022RJ chassis mount resistor can also provide engineers with cost savings in terms of time and resources. Utilizing these resistors can help reduce the manpower required to install multiple components and the associated wiring. Additionally, these resistors help improve product reliability and ensure consistent output over the long term, which helps reduce unexpected maintenance costs.

Conclusion

The HSA1022RJ chassis mount resistor is suitable for a wide range of applications in power supplies, power management circuits and other related areas. This resistor features excellent thermal protection, moisture and dust protection, and reliable electrical contact, making it an ideal choice for those looking for durable, cost effective, and long-lasting solutions for their applications.
