<Set PTC Used>

<Function of PRF>

<Competitive Device>

Chip THERMISTORS prevent failure of apparatus due

to excess current.

1. 0603 and 0805 light weight

2. High gain simplifies circuit design

3. Free of contact noise and problems

4. Pb free plated terminations.

5. Sturdy construction resists mechanical

vibration and shock.
