At currents below the device IHOLD rating, AND at temperatures below 100C, the PTC maintains a resistance value below its R1 MAX rating. OZCC Apr2013C As the device's temperature approaches 130C, either due to an increase in ambient temperature or a current exceeding its | TRIP rating, volumetric expansion of the filled polymer breaks apart the majority of conductive pathways across the terminals created by chain contact of adjacent filler particles and device resistance increases sharply by several orders of magnitude. At the much higher Tripped resistance, there is just enough leakage current to allow internal heating to hold the device in its tripped state (around 125C) until power is interrupted. Once power is removed, the PTC's core cools and contracts allowing conductive chains to reform and return the device to its low resistance state. The catalog data for each device specifies a "Typical Power value. This is the power required to exactly match the heat lost by the tripped device to its ambient surroundings at 23C. By Ohm's Law, power can be stated as: W = E*2/R. Thus the approximate resistance of a Tripped PTC can be determined by: R= E*2/W, where "E" is the voltage appearing across the PTC (usually the supply's open circuit voltage), and "W" is the Typical Power value for the particular PTC. Since the PPTC acts to maintain a constant internal temperature, its apparent resistance will change based upon applied voltage and, to a lesser degree, ambient conditions. Consider the following example.... A PTC with a Typical Power of 1 watt protecting a circuit using a GOV supply will demonstrate an apparent, tripped resistance "R" of: R = 60*%2/1 = 3,600 ohms This same tripped device when used to protect a 12V circuit would now present an apparent resistance of: R = 1242/1 = 144 ohms The value for Typical Power is "typical" because any physical factors that affect heat loss (such as ambient temperature or air convection) will somewhat alter the level of power that the PTC needs to maintain its internal temperature. In short, PTCs do not exhibit a constant, quantifiable tripped resistance value. Typical Time - To - Trip at 23C (See Elec.

NR aw Cautionary Notes Operation beyond the specified maximum ratings or improper use may result in damage and possible electrical arcing and/or flame. . 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. . Avoid contact of PTC device with chemical solvent. Prolonged contact may adversely impact the PTC performance. . 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. . These devices are intended for use in DC voltage applications only. Use in AC voltage applications should be first discussed with Bel Fuse engineering . Not recommended for use on potted or conformal coated PCB's. Restriction of free air flow could affect -40 -20 0 20 40 80 electrical performance and/or result in device failure Ambient Temperature (C ) Consult Bel Fuse engineering. 7. In the Indeterminate Performance / grey zone, Hold Current Tr p Current tripping may occur but cannot be relied upon.
