A 4pyF (or greater) film capacitor such as: ITW Paktron Capstick series, part number 405K100CS4 4pyF/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.
