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 4µF (or greater) film capacitor such as: ITW Paktron Capstick series, part number 405K100CS4 4µF/100V 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 A top mounted heatsink kit is available for the BXA40. The heatsink may be oriented parallel to or perpendicular to the direction of the pins, thus providing 0.019 optimum flexibility for cooling requirements. The order (0.50) number for the top mounted heatsink kit with metric screws is ‘NFC40-HTSK-T’. The order number for the top mounted heatsink kit with imperial screws is ‘NFC40-HTSK-T-I’.
