Radial Leaded PTC OZRC Series -® OZRC Series Fuse RoHS 6 Compliant 8t Halogen-Free PTC's — Basic Theory of Operation / ‘Trlpped~ Resistance Explanation Fundamentally, a Bel FTC consists of a block of polymeric material containing conductive filler and bonded between two conductive, planar terminations, At currenls below the device lHOLD rating, AND at temperatures below 1000, the FTC maintains a resistance value below its R1 MAX rating. As the device‘s temperature approaches 130C, either due to an increase in ambient temperature or a current exceeding its ITRIP rating, volumetric expansion of the filled polymer breaks apart the majority of conductive pathways across the terminalzcreated by chain contact of adjacent filler particles or device resistance increases sharply by several orders of magnitu e, At the much higher “Tripped” resistance, there is just enough leakage current to allow internal healing to “hold" the device in its tripped state (around 1250) 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 230 By Ohm's Law, power can be stated as: w : EAz/R. Thus the approximate resistance of a “Tripped” PTC can be determined by: R : EA2/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 PTCi 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 60V supply will demonstrate an apparent, tripped resistance "R" of: R : 60A2/1 : 3,600 ohms This same tripped device when used to protect a 12V circuit would now present an apparent resistance of: R :12A2/1:144 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, Type Time - To - Trip at 23°C (See Elec.
