(R) MH80626C Battery Feed/Protection SIP Preliminary Information Features * * * * 2 x high power, high voltage, thick film surge protection resistors 2 x high accuracy, high stability matched battery feed resistors 2 replaceable 2AG fuses in surface-mounted fuse clips Used with the MH89626C for a complete OPS line interface MH80626C ISSUE 2 April 1995 Ordering Information 20 Pin SIL Package 0C to 70C Description The MH80626C hybrid SIP provides a protection circuit consisting of two 2AG size fuses in surfacemounted fuse clips and two high voltage, high power 5.5 surge resistors. The MH80626C also provides two high stability, high power 50 feed resistor matched to 0.1%. The SIP provides full secondary protection for the MH89626C Off-Premise SLIC, allowing conformance to the requirements of various international safety and performance standards.
