Through Hole Resistors

RR01J39RTB application field and working principle

High-power through hole resistors are broadly applied in a variety of power electronic products, circuit protection, industrial instrumentation, home appliance, office equipment, and motor drivers that call for good heat radiation and bulk tolerance of overheat and huge electric current. RR01J39RTB is a type of through hole resistors. It is a surface-mount power resistor for high-current and high-voltage application. With its compact size and metal plate, this resistor type is suitable for long-time full-load as well as devices that need quick temperature adjustments. The working principle of through hole resistors in general can be described as follows. It starts with the resistance materials being exposed to a high current, creating a joule-heating effect which increases the temperature of the component and induces thermal radiation that promotes heat dissipation. The resistance materials also act as magnetic field shields which helps protect the circuit and reduces noise. The output of the resistor is also usually affected by the environmental humidity and temperature, which needs to be measured and taken into consideration when selecting and installing the resistor. The materials used for RR01J39RTB are silvered molybdenum and steel, which is a combination of nickel-plated copper, aluminum, and alloy steel. The construction is designed for efficient heat radiation and fast temperature adjustments. This type of resistor consumes up to 0.2 watts of power in the worst case scenario, and has an operating temperature range between -40°C to +125°C. RR01J39RTB can handle up to 200 amps of overload current, 500V of surge protection voltage, ambient temperatures between -40°C to +125°C, and a depth of 40mm. It is suitable for harsh environment and also provides good anti-vibration as well as anti-shock performance. RR01J39RTB is commonly used for DC/DC converter, power electronic terminals, heaters, circuit protection, industrial device, security system, motor drives, and automotive applications. Through hole resistors are widely used in a variety of electrical and electronic device due to their good thermal dissipation, magnetic field shield, and anti-vibration performance. RR01J39RTB is designed for long-term power supply under high current and voltage conditions, and it is typically applied in harsh environment with a wide operating temperature range. With its heat radiation and fast temperature responsiveness, RR01J39RTB provides a good choice for industrial and automotive applications that require reliable performance.
