PTC Features:
The Polymer PTC resettable fuse is commonly used for connnecting to the tweeter positive. Its role: When the tweeter works in small current, its resistance is
very small, small to 0.1Ω, PTC does not act, act as a connecting line; The experiment proved that the treble voice coil heats when it works in a large current,
and when the tweeter working current exceeds the load, the PTC acts, it will increase the resistance, which limits the current to increase, then the horn is
protected without any sound. When the pressured current or voltage disappears, PTC can be restored automatically. If your treble speaker is often burnt out,
you can buy it to connect to the positive of the speaker. Of course, the protection is limited. When the current exceeds the load too large, the PTC will be also
damaged.
The PTC model code is from 010-375, their voltages are 60V, and their destroyed currents are 40A. The model code comparison: the model code is small, and
its startup current is small, but its resistance is large; The model code is large, and its startup current is large,but its resistance is small.
