Description Of The Non-Resettable Quick Blow Surface Mount Ceramic Fuse 1032

Non-resettable surface mount fuses are single-use circuit protection devices that break a circuit when a fault is detected. This type of fuse is designed to be mounted directly onto a printed circuit board (PCB).

Non-resettable surface mount fuses offer circuit protection by breaking the circuit when detecting a fault. They are designed to be mounted directly onto a printed circuit board (PCB) and are available with a range of voltages, current ranges and resistance levels. They work by melting the metal strip inside the fuse during and overcurrent or short circuit event, which means they must be replaced once the fuse has blown.
We supply a variety of non-resettable surface mount fuses suitable for a range of applications, from manufacturers including one time fuse and resettable fuse.

Operating Characteristics

Choosing between a PTC and a Fuse

Overcurrent circuit protection can be accomplished with the use of either a traditional fuse or the more recently developed resettable PTC. Both devices function by reacting to the heat generated by the excessive current flow in the circuit. The fuse melts open, interrupting the current flow, and the PTC changes from a low resistance to a high resistance to limit current flow. Understanding the differences in performance between the two types of devices will make the best circuit protection choice easier.

The most obvious difference is that the PTC is resettable. The general procedure for resetting after an overload has occurred is to remove power and allow the device to cool down. There are several other operating characteristics that differentiate the two types of products. The terminology used for PTCs is often similar but not the same as for fuses. Two parameters that fall into this category are leakage current and interrupting rating.

Leakage current: the PTC is said to have “tripped” when it has transitioned from the low resistance state to the high resistance state due to the overload. Protection is accomplished by limiting the current flow to some leakage level. Leakage current can range from around a hundred milliamps at rated voltage up to several hundred milliamps at lower voltages. The fuse on the other hand completely interrupts the current flow and this open circuit results in “0” leakage current when subjected to the overload.

Interrupting rating: the PTC is rated for a maximum short circuit current at rated voltage. This fault current level is the maximum current that the device can withstand but the PTC will not actually interrupt the current flow (see LEAKAGE CURRENT above). A typical PTC short circuit rating is 40A. Fuses do in fact interrupt the current flow in response to the overload and the range of interrupting ratings goes from hundreds of amperes up to 10,000 amperes at rated voltage.

The circuit parameters may dictate the component choice based on typical device rating differences.

Voltage rating: general use PTCs are not rated above 60V while fuses are rated up to 600V. Current rating: the operating current rating for PTCs can be up to 11A while the maximum level for fuses can exceed 20A.

Temperature rating: the useful upper limit for a PTC is generally 85° while the maximum operating temperature for fuses is 125°C. Both devices require derating for temperatures above 20°C and a representative curve for that purpose is provided.

The PTC Rerating Curves located on data pages, should be consulted for the proper rerating of the various PTC series at ambient temperatures other than 20°C.

Additional operating characteristics can be reviewed by the circuit designer in making the decision to choose a PTC or a fuse for overcurrent protection.

Agency approvals: PTCs are recognized under the Component Program of Underwriters Laboratories to UL Thermistor Standard 1434. The devices have also been certified under the CSA Component Acceptance Program. PTCs can, in addition, be approved to IECStandard 730-1 (Automatic Electric Controls) with certification by TUV, VDE, etc. Approvals for fuses include recognition under the Component Program of Underwriters Laboratories and certification from the CSA Component Acceptance Program. In addition many fuses are available with full “Listing” in accordance with the new Supplementary Fuse Standard UL 248-14.

Resistance: Reviewing product specifications indicates that similarly rated PTCs have about twice (sometimes more) the resistance of fuses. Time-current characteristic: comparing the time-current curves of PTCs to fuses shows that the speed of response for a PTC is similar to the time delay of a Slo-Blow fuse.
