Additional Details:

The CMPT5089 transistor has a collector-emitter voltage (VCEO) rating that ensures it can handle a specific voltage range without breakdown. Its collector current (IC) rating indicates the maximum current it can safely handle. The power dissipation rating specifies the maximum power the transistor can dissipate without exceeding its thermal limits. The operating and storage temperature ranges are also important considerations for ensuring the transistor's reliability in different environments. The noise figure, typically specified in decibels (dB), is a critical parameter for low-noise applications. The DC current gain (hFE) is an important parameter to consider when designing amplifier circuits. This part is typically supplied in tape and reel packaging for automated assembly processes.
