This is now the standard Duty Cycle and is no longer needed in CC the part number. We will still support part numbers with the S. For example: SM7745HW and SM7745HSW describe the same specifications and can be used interchangeably by the customer. -30 Denoted Output Load other than the standard 15 pF. Data sheets now reflect the specifications at all available loads so this load designation is no longer needed. Well still support part numbers with this load designation. www.pletronics.com 425-776-1880 2
