    Plug these adapter cords into a standard outlet and they change AC voltage to DC voltage. These cords use switching regulation, so they produce the stated voltage even when your outlet’s power or the power drawn by your device fluctuates. It also means they won’t get too hot. They have an LPS low-voltage output and Class II shock protection, so if something fails inside these cords, they’ll limit the risk of electrical shocks. These cords meet U.S. and Canadian safety standards as well as U.S. DOE (Department of Energy) Level VI standards for energy efficiency.
    When choosing an adapter, match the output voltage and polarity of your device. Look for the polarity illustration on your device or the adapter you're replacing. The current you choose should, at a minimum, match your device. You can choose a higher current, but it will not improve performance.

    Swap the plug to match the outlet of the region you’re in instead of using separate cords for each country. These adapter cords convert AC voltage to power DC electronics. Designed with switching regulation, they maintain consistent voltage during power fluctuations and don’t get too hot. They meet U.S., Canadian, European, Australian, New Zealand, and Chinese safety standards.
    A limited power source (LPS) low-voltage output decreases the risk of electric shock if something fails inside these cords. Class II shock protection means they have two levels of insulation. These cords meet U.S. DOE (Department of Energy) Level VI standards for energy efficiency when they're in-use, as well as when they're plugged in but not in use.
    Choose an adapter cord with an output voltage that matches the voltage of your device. The polarity of the adapter cord and your device must also be the same. Look for the polarity illustration on your device or the adapter cord you’re replacing and pick a cord to match.

    Couple these adapters with a cord that matches your outlet and length requirements to run DC-powered electronics. Instead of plugging directly into an outlet, the body of these adapters sits on the floor or other surface, so it remains out of the way and won’t block multiple outlets. These adapters use switching regulation—they produce the stated voltage even when your outlet’s power or the power drawn by your device fluctuates. Most have an LPS low-voltage output, so if something fails inside these adapters, they’ll limit the risk of electrical shocks. They meet U.S., Canadian, and European safety standards. Many also meet U.S. and European standards for energy efficiency.
    When choosing an adapter, match the output voltage and polarity of your device. Look for the polarity illustration on your device or the adapter you're replacing. The current you choose should, at a minimum, match your device. You can choose a higher current, but it will not improve performance.
    IEC C8—Adapters with an IEC C8 input require power cords with a C7 socket. With Class II shock protection, they have two levels of insulation that prevent electrical shocks.
    IEC C14—Adapters with an IEC C14 input require power cords with a C13 socket. They have Class I shock protection and prevent electrical shocks with a combination of insulation and a protective ground.

    Diode Assortments

    Control voltage and current in circuits with a variety of diodes.
    Standard, Schottky, and Zener Diodes
    Image of Product. Front orientation. Diodes. Diode Assortments, Standard Diode.
    Standard diodes keep the current in a circuit flowing in one direction. Use them to manipulate signals or to protect your circuit from reverse currents, such as those created when a motor stops or slows down.
    Schottky diodes have faster switching speeds than other diodes, so they’re used to channel current in a single direction in circuits that switch frequently. They’re often found in radios and data processors.
    Zener diodes regulate voltage in a circuit. When installed in reverse, they won’t conduct current until a set voltage is reached. After that point, they maintain the same voltage. Because they provide a stable voltage, they are often used as a reference point in amplifiers and other voltage-sensitive circuits.

    Voltage-Stabilizing Diodes

    Image of Product. Front orientation. Diodes. Voltage-Stabilizing Diodes.
    Power sections of a circuit with a specific voltage. Also known as Zener diodes, these diodes are often used as a reference point in amplifiers and other voltage-sensitive circuits. When installed in reverse, they won’t conduct current until the reverse breakdown voltage is reached. After that point, they maintain the same voltage.
    Reverse Breakdown Voltage—Reverse breakdown voltage is the voltage at which a reversed current will break through the diodes’ internal electrical barrier and flow backward.
    Forward Voltage Drop—Forward voltage drop is the amount of voltage used up while current flows across diodes.
