e/TO-18

Information
has gloss	eng: The TO-18 is a common style of transistor enclosure construction, particularly among older models and models susceptible to interference. The case is made of metal and is therefore more expensive than the plastic TO-92 package. However, the TO-18 offers superior noise isolation and thermal protection than plastic cases, while maintaining a small form-factor.
