Power and AC Film Capacitors – Printed Circuit Board Mount Power Film Capacitors C4AF, Radial, 2 or 4 Leads, 250 - 500 VAC, for Harsh Environment AC Filtering (Automotive Grade) Soldering Process The implementation of the RoHS directive has resulted in the selection of SnAuCu (SAC) alloys, or SnCu alloys, as the primary solder material. This has increased the liquidus temperature from 183°C for a SnPb eutectic alloy to 217 – 221°C for new alloys.
