Surface Mount PTC Thermistors

For Overload Protection

FEATURES

• Ideal for pick-and-place circuit assembly

• Low mounting height

• Suitable for reflow soldering

• Small ceramic diameter for faster response

• Low heat transfer to substrate

• Flat terminations for stable positioning and good

solderability.

APPLICATIONS

• Telecom

– Central office switching (C.O.)

– Subscriber terminal equipment (T.E.)

– Set top box

DESCRIPTION

at 70 °C

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.
