Overcurrent circuit protection can be accomplished with the use of either a traditional fuse or PPTC (positive temperature coefficient) device. PPTCs are typically used in a wide variety of telecom, computer, consumer electronics, battery and medical electronics product applications where overcurrent events are common and automatic resettability desired.

If your application requirements fall outside of our product range, in certain instances we can offer customized solutions. Please contact Littelfuse for more information.

Both Polymeric (Positive Temperature Coefficient) PPTC and traditional Fuse devices react to heat generated by the excessive current flow in a circuit. A fuse melts open, interrupting the current flow whereas a PPTC limits current flow as it rises in temperature, changing from low to high resistance state. In both cases this condition is called "tripping." The graph at right shows the typical response of a PPTC to temperature.

Littelfuse Polymer PPTCs are made chiefly of high density polyethylene mixed with graphite. During an overcurrent event, a Polymer PPTC will heat and expand, which in turn causes the conducting particles to break contact and stop the current.

When a PPTC is in a "tripped state" it protects the circuitry by limiting the current flow to a low leakage level. Leakage current can range from less than a hundred milliamps (mA) at rated voltage up to a few hundred milliamps (mA) at lower voltages. Fuses on the other hand completely interrupt the current flow when tripped, and this open circuit results in no leakage current when subjected to an overload current.

PPTCs are rated for a maximum short circuit current at rated voltage also known as "breaking capacity" or Imax. This fault current level is the maximum current that the device can withstand safely, keeping in mind that the PPTC will not actually interrupt the current flow (see Leakage Current above). A typical Littelfuse PPTC short circuit rating is 40A; or for the battery strap PPTCs, this value can reach 100A. Fuses do in fact interrupt the current flow in response to the overload and the range of interrupting ratings, vary from tens of amperes (A) up to 10,000 (A) amperes at rated voltage.

Littelfuse PPTCs are Recognized under the Component Program of Underwriters Laboratories to UL Standard 1434 for Thermistors. The devices have also been certified under the CSA Component Acceptance Program.

Comparing the time-current curves of PPTCs to time-current curves of fuses show that the speed of response for a PPTC is similar to the time delay of a Littelfuse Slo-Blo® fuse.

The temperature rerating curves in the table below compare PPTCs to fuses and illustrate that more rerating is required for a PPTC at a given temperature.

Looks like I got hit with the magic drop of coffee. My MBPr backlight is off but the LCD data on the screen appears fine. Both external video ports also work. I have taken a look inside and noticed a tiny little drop of coffee on the bottom case near the video cable. there appears to be no other damage or corrosion. I have spot cleaned the area with rubbing alcohol with the battery unplugged. Although its still under warranty, It will take 7 days and I would likely be hit with a "water-damage" fee which exceeds $1200 on this machine. After much research and past experience I believe that this 2A 0402 fuse is blown and needs to be replaced, $6 for 10 LOL. Before I take it into my local tech for metering and replacement with his magical solder tweezers for surface mount components, I want to order the replacement fuses and have them with me.
