The KHHD series is a DOSA standard sixteenth brick footprint operating with 18 V to 75 V input and 3.3 V, 5 V, or 12 V output. These modules are available in surface mount, tape and reel versions with product features that include positive and negative on/off logic, auto restart, overcurrent and over-temperature protection, and shorter through-hole trim pin. These bricks are useful in circuits where a DC input voltage within the range of 18 V to 75 V needs to be converted to a standard voltage bus and isolation is required. Common applications include the networking and data com applications, but also optical and access networking equipment, hybrid power architectures, and many industrial applications.
