For EMI compliance to EN55022 level A, refer to BXA40 Design Note 101. 7 Reverse voltage protection, refer to BXA40 Design Note 101. 8 The maximum operating ambient temperature, without derating depends on internal power dissipation and module efficiency and cooling method. Download BXA40 Design Note 101 which provides detailed thermal calculations and design-in hints from the Artesyn website. 9 It is suggested that an external filter capacitor be used. A 4 F (or greater) film capacitor such as: ITW Paktron Capstick series, part number 405K100CS4 4 F/100 V is recommended, if filtering is not used. See BXA40 Design Note 101. 10 The unit with the suffix `-M' at the end of the model number is offered as standard with metric threaded inserts (M3). To order a unit with imperial threaded inserts (4-40 UNC) please remove the suffix `-M' from the model number. These inserts are used for bolting the unit to a PCB and/or fixing heatsinks. 11 The `J' suffix indicates that these parts are Pb-free (RoHS 6/6) compliant. TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details. 12 NOTICE: Some models do not support all options.
