On some digital flasher relays, significantly these utilized in automotive functions, “EF” typically denotes “digital flasher.” This marking differentiates it from thermal flasher items, which depend on a heating factor and bimetallic strip to create the flashing impact. An digital sort makes use of solid-state circuitry to regulate the on/off biking of the lights. As an example, an EF90 flasher relay can be an digital unit designed to deal with a selected load, usually indicated by the “90.”
The significance of understanding this designation lies in deciding on the right element for a automobile’s lighting system. Digital flashers provide a number of advantages over their thermal counterparts, together with better reliability, longer lifespan, and the flexibility to operate correctly with LED bulbs, which draw considerably much less present. Traditionally, thermal flashers have been the usual, however the growing adoption of LED lighting has pushed the transition in the direction of digital options.
