  • Current-Carrying Capacity and Voltage Ratings of RRC-MC35-180/30: A Technical Examination

    The RRC-MC35-180/30 battery connector stands at the forefront of power connectivity, playing a pivotal role in meeting the escalating demands for energy storage in our technologically advancing world.

    As electronic devices become more sophisticated and power-hungry, the reliability and efficiency of battery connectors have skyrocketed.

    Let’s learn more:

    Current-Carrying Capacity of RRC-MC35-180/30

    Current-carrying capacity refers to the maximum amount of current that a conductor can safely carry without overheating or causing damage. In the case of the RRC-MC35-180/30, the current-carrying capacity is determined by several factors:

    ● Material properties: The connector is made of high-quality materials such as copper alloy contacts and a thermoplastic housing with a UL 94 V-0 flame retardancy rating. These materials ensure good conductivity and thermal stability, allowing the connector to handle high currents without overheating.

    ● Contact design: The RRC-MC35-180/30 features two power pins with a larger contact area compared to the four signal pins. This design allows the power pins to handle higher currents without exceeding their temperature limits.

    ● Operating temperature: The current-carrying capacity of the connector decreases as the operating temperature increases. This is because higher temperatures can increase the resistance of the conductor, leading to more heat generation.

    ● Wire gauge: The thicker the wire gauge used with the connector, the higher the current-carrying capacity.

    ● Connection quality: A poor connection can increase the contact resistance, leading to higher temperatures and reduced current-carrying capacity.

    ● Environmental factors: Dust, dirt, and moisture can also affect the current-carrying capacity by reducing the efficiency of heat dissipation.
