Cautionary Notes

1. Operation beyond the specified maximum ratings or improper use

may result in damage and possible electrical arcing and/or flame.

2. These Polymer PTC (PPTC) devices are intended for protection

against occasional overcurrent/overtemperature fault conditions

and may not be suitable for use in applications where repeated

and/or prolonged fault conditions are anticipated.

3. Avoid contact of PTC device with chemical solvent. Prolonged

contact may adversely impact the PTC performance.

4. These PTC devices may not be suitable for use in circuits with a

large inductance, as the PTC trip can generate circuit voltage

spikes above the PTC rated voltage.

5. These devices may be used in both DC and AC circuits provided

that peak-to-peak line voltage when carrying AC does not exceed

the PTC’s Vmax rating. As PTCs are essentially thermal devices,

the RMS value of AC current carried by a PTC will produce

tripping parameters and times-to-trip similar to those of a DC

voltage of the same magnitude.

6. If potting is mandated, avoid rigid potting compounds as they will

encase the PTC and prevent it from volumetrically expanding to

properly respond to a trip event.

7. MSL: 2a (According to IPC J-Std-020).
