The ceramic is soldered to the leadframe by a local reflow process, during which the solder layer is melted to the metallized ceramic surface using a low residue flux. MARKING • All TWIN Vertical SMD PTC’s are marked with the last 3-digits of the type number (BCxxx) and a date code (YYWW) Over-temperature/over-load protection: • Telecom - Telecommunications infrastructure - PABX - Set-top box MOUNTING With a flat pick-up area = 30 mm2 the PTC thermistors are suitable for processing on high speed automatic insertion equipment. Typical soldering 235 °C, duration: 5 s (Pb-bearing) 245 °C, duration: 5 s (Lead (Pb)-free) Resistance to soldering heat 260 °C, duration: 10 s max.
