PPTC is the Polymeric Positive Temperature Coefficent, that is, polymer Positive coefficient Temperature resistance, also known as Resettable Fuse, is widely used in communication, power, industrial control, security, instrumentation and other fields.
SPSEMI has launched YGM120M series of high voltage patch PPTC products with a maximum voltage of 250V(AC), which can replace the traditional plug-in high voltage PPTC for miniaturization and lightweight. At the same time, the SMT process, with better welding reliability and production yield, also brings customers high cost performance benefits beyond the device.
When selecting PPTC, determining the maximum voltage Vmax is the first consideration. PPTC as a protective electronic component, its own certainly can not appear the hidden danger of safety. PPTC may be broken down in the case of over voltage or over current. Therefore, the Vmax must be taken as the primary evaluation factor, and a higher voltage tolerance should be selected and a larger margin should be reserved. In this way, the probability of PPTC breakdown and failure can be reduced even if the system line voltage is abnormal occasionally.
SPSEMI YGM120M series PPTC, with Vmax=250V excellent pressure, good to meet the needs of customer selection.
