I hold = Hold current: maximum current device will pass without tripping in 20°C still air. 

I trip = Trip current: minimum current at which the device will trip in 20°C still air. V I maxmax = Maximum fault current device can withstand without damage at rated voltage (V = Maximum voltage device can withstand without damage at rated current (I max) max) 

R min = Minimum resistance of device in initial (un-soldered) state. R typ = Typical resistance of device in initial (un-soldered) state. 

R 1max =  Maximum resistance of device at 20°C measured one hour after tripping or reflow soldering of 260°C for 20 sec. 

P d = Power dissipated from device when in the tripped state at 20°C still air. 

**Caution:** Operation beyond the specified rating may result in damage and possible arcing and flame. 

> **1** Some older references to these devices may include “–C“ in the Part Number. The “–C“ should be omitted when placing new orders for the device. 

> **2** Part Number with note 2 tested and complied with AEC Q200.

## **Warning** 

- Users shall independently assess the suitability of these devices for each of their applications 

- ■ Operation of these devices beyond the stated maximum ratings could result in damage to the devices and lead to electrical arcing and/or fire 

- These devices are intended to protect against the effects of temporary over-current or over-temperature conditions and are not intended to perform as protective devices where such conditions are expected to be repetitive or prolonged in duration 

- Exposure to silicon-based oils, solvents, electrolytes, acids, and similar materials can adversely affect the performance of these PPTC devices 

- These devices undergo thermal expansion under fault conditions, and thus shall be provided with adequate space and be protected against mechanical stresses 

- Circuits with inductance may generate a voltage (L di/dt) above the rated voltage of the PPTC device.
