Description
The Bel VRBC-10F2Ax modules are a series of non-isolated dc/dc converters that deliver up to 10 A of output current with full load efficiency of 94% at 3.3 Vdc output. These modules provide precisely regulated voltage programmable via external resistor from 0.75 Vdc to 3.63 Vdc over a wide range of input voltage (2.4 Vdc - 5.5 Vdc). These modules have a sequencing feature that enables designers to implement various types of output voltage sequencing when powering multiple voltages on a board. The open-frame construction and small footprint enable designers to develop cost and space-efficient solutions. Standard features include remote On/Off, remote sense, over current protection, short current protection, wide input, and programmable output voltage.

xRAH-01K - NON-ISOLATED DC/DC CONVERTERS

Description
SMP Surface Mount Power Cross Protection Fuses are primarily intended for use in telecommunication circuit applications requiring low current protection with high surge tolerance.
They are typically used to replace heat coil type devices.
They are designed to be placed between the line input and the surge arresting components (mov. gas tube, zenor diode, air gaps, etc.)
These fuses will withstand transient surge currents generated by lightning in accordance with the attached table.
SMP Fuses guard protected circuitry against sustained overload or short circuit conditions. Such sustained overloads may be generated by accidental contact between utility cables and phone lines (power line cross).
SMP Fuse are used in circuits to obtain compliance with the test requirements specified in UL 1950/60950 and Bellcore GR 1089.

Description
The Bel xRAH-08Exxx modules are a series of non-isolated, step down dc/dc converters that operate from 4.5 Vdc to14 Vdc source. These converters are available in a range of output voltages from 0.8 Vdc to 5.5 Vdc. It is packaged in a compact, overmolded package rated at 8 A. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. The output is closely regulated and the efficiency for 5 Vdc output is typically 93% at full load.
