Square Transistor Outline Caps

In opto-electronics, transistor outline caps and lids fulfill two primary functions: they protect the optical components of transmission as well as reception applications, and ensure the transmission of optical signals by acting as an optical interface. Rectangular caps and lids are used for opto-electronic applications such as sensors and LED packages. Features include fitting to rectangular glass-to-metal and ceramic packages, deep drawn metal can for direct soldering onto ceramic packages, availability with lens or flat window designs in round or rectangular shaped windows, glass with UV transmission, reliable hermeticity, and high thermal and mechanical stability.
