Fast Response Resettable Reset Polymer PTC Fuse JK30 160

Product Overview

Description

Fast Response Resettable Reset Polymer PTC Fuse JK30-160    

 

Description

 

The 30R Series radial leaded device is designed to provide overcurrent protection for low voltage (≤30V)
applications where space is not a concern and resettable protection is preferred.

 

Features

 

• Cured, flame retardant epoxy polymer insulating material meets UL 94V-0 requirements
• Fast time–to-trip
• RoHS compliant, Lead-Free and Halogen-Free* 

 

Application

 

These devices are often used in computer power supplies, largely due to the PC 97 standard (which recommends a sealed PC that the user never has to open), and in aerospace/nuclear applications where replacement is difficult.[citation needed] Another application for such devices is protecting audio loudspeakers, particularly tweeters, from damage when over driven: by putting a resistor or light bulb in parallel with the PPTC device it is possible to design a circuit that limits total current through the tweeter to a safe value instead of cutting it off, allowing the speaker to continue operating without damage when the amplifier is delivering more power than the tweeter could tolerate. While a fuse could also offer similar protection, if the fuse is blown, the tweeter cannot operate until the fuse is replaced.

I trip = Trip current: minimum current at which the device will trip in 20°C still air. V max = Maximum voltage device can withstand without damage at rated current (Imax) I max = Maximum fault current device can withstand without damage at rated voltage (Vmax) Pd= Power dissipated from device when in the tripped state at 20°C still air. R min = Minimum resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 20°C measured one hour after tripping. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
