VALUE STANDARD TELECOM TYPES (1) (2) TYPES (1) (2)
2 to 500 10 to 70 10 %; 15 %; 20 % 2 to 10 A 50 to 500 mA at 25 C 16 to 400 V (RMS) <1s down to 0.5 50 to 100 mA at 70 C 220 to 600 V (RMS)

DESCRIPTION
The component consists of a high-performance PTC ceramic disc mounted in a lead-frame for direct soldering onto a printed-circuit board (PCB) or substrate. 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.

Notes: (1) Customized products are available on request (2) Coated and/or reinforced types are available on request

MARKING
All SMD PTCs are marked with the last 3-digits of the type number (XXX) and a date code (YYWW)
