The converters are typically used in general purpose and industrial low ower isolation and voltage SMD matching applications where an SMD converter is required. The converter series feature an extended ambient temperature operating range of -40C to +100C without derating and optional continuous short Single, Dual and circuit protection. In addition to single, dual and independent outputs, two isolation options and three different case formats, the converters are also available prepacked as tape and reel for use with Independent automatic insertion machines.
