    Use attention

    ■ After the storage period of newly purchased parts exceeds 6 months, attention should be paid to weldability before use. It is recommended to store in vacuum packaging.
    ■ The ground needs optimal heat transfer.
    ■ The manual welding lead should be used under a constant temperature soldering iron of no more than 350 degrees, and the welding time should be controlled within 5 seconds.
    ■ In order to meet the drawing requirements, it is necessary to install a sufficiently large radiator. Metal surfaces and radiators need to be coated with a very thin layer of thermal grease.
    ■ If necessary, add air or water cooling.

    ◆ Instructions:
    ■ Custom designed RF attenuators, RF resistors and RF terminals are available.
