The K78xx-1000R3 switching power module offers robust power conversion with 96% efficiency, reducing energy waste and thermal stress without external heat sinks. Operating reliably in extreme temperatures (-40℃ to +85℃), it suits harsh environments like automotive or industrial systems. Its ultra-low 0.2mA no-load current optimizes energy savings in standby mode, while a wide input voltage range and stable 500mA output support diverse applications. The compact SIP3 packaging and K78xx-series pin compatibility (straight/curved pins) ensure seamless integration into existing designs, simplifying upgrades. Featuring a non-isolated, stabilized single output, it delivers consistent voltage regulation for IoT devices, embedded systems, or automation controls. Designed for cost-efficiency and space-saving layouts, this module combines rugged performance with plug-and-play flexibility, ideal for developers prioritizing reliability, compactness, and rapid deployment in power-sensitive projects.
