Microdetonators functioned as inconspicuous explosives, essentially detonators designed for discreet use. These devices offered a subtle method for initiating small, precise blasts, and their utility was enhanced by the inclusion of a timer mechanism. A notable instance involves Brand, previously a bounty hunter but then serving as a soldier within the Rebel Alliance's 61st Mobile Infantry, employing a microdetonator to obliterate a chemical barrel situated inside the Galactic Empire's Distillery. This event transpired on Coyerti, a planet covered in jungle located in the Mid Rim, during 3 ABY. The resulting explosion served as a major diversion, shifting the focus of Imperial staff towards a possible saboteur and the chemical spill. Following the blast, Brand's squad successfully managed to destroy the entire facility.
The 2015 novel Battlefront: Twilight Company, penned by Alexander Freed, featured the use of Microdetonators.
