0.81 mm mini-coaxial cable is typically found inside devices that require high-frequency transmission up to 6 GHz, such as in cellular modems and GNSS transceivers. It is also used in medical equipment and military installations due to its compact size and reliable performance. The cable is most commonly used to connect micro connectors such as MHF4 to surface mount connectors on the chipset.
