SS9018 Transistor Explained / Description:

SS9018 is a NPN silicon transistor. It is manufactured to work in radio frequency applications but it can also be used as a switch or amplifier for audio and signal amplification purposes. One of the main difference between this transistor and other BJT transistor is its 1100MHz or 1.1GHz bandwidth. The normal BJT transistors can work from 50MHz to 300MHz but this transistor can work with much higher frequencies due to which it can be an ideal transistor to use in variety of RF applications.It is also widely used by electronic tinkers & hobbyist. Moreover it is also used in variety of commercial appliances and devices.



Where We Can Use it & How to Use:

As mentioned above SS9018 is built to work in RF applications therefore it can perform well in these type of circuits. Moreover this transistor is an NPN BJT transistor therefore it can be wired same as a normal BJT transistor is wired in a circuit.

How to Safely Long Run in a Circuit:

It is always suggested not touch the maximum ratings, for getting long term stable performance with a component. Using a component to its maximum rating or near its maximum ratings provides stress on a component that may result in failure of a component in a circuit or not provide expected performance. To get long term performance with SS9018 do not operate load more than 15V through it, do not drive load more than 50mA and always store and operate the transistor above -55 centigrade and below +150 centigrade.
