WH60 series resettable fuse (WHPTC) products are widely used in higher rated working voltage circuits, such as micro-motors, speakers, transformers, security equipment, industrial control, test and measurement equipment, satellite receiving systems, the t
WH130 series resettable fuse (WHPTC) is widely used in the circuit of rated voltage less than 130V, especially in Europe and the United States electrical line voltage of 110V 120V situation Such as: lamps, ballasts, transformers, motors and other fields
WH250 series resettable fuse (WHPTC) for program-controlled switches, patch panels designed and manufactured over protection device, but can also used in transformers, security equipment, lamps, ballasts, meters, telephone lines and other fields
WH600 series resettable fuse (WHPTC) for program-controlled switches, patch panels designed and manufactured over protection device, but can also used in transformers, security equipment, lamps, ballasts, meters, telephone lines and other fields
The company passed the ISO9001: 2000 quality system certification, ISO14001: 2004 environmental management system certification and UL TUV CQC and many other safety certification, all products comply with the EU RoHS Directive
Power supply with a transformer failure is mainly due to an overcurrent generated, resulting in over-current is usually due to a short circuit or load decreases; failure will cause the circuit to smoke, fire, so that damage to the circuit and interfaces
Speaker system protection requirements more stringent Ordinary fuse from the speaker only disposable protective effect, the product failure rates rise; addition, extra fuse box and wires to make the manufacturer s costs
Usually in a communication device designed for the protection circuitry Protection devices commonly classified according to the principle, there are over-voltage protection, over current protection, over temperature protection and EMI protection
pptc components can be used in photovoltaic power generation system of communication ports, photovoltaic panels, inverters, batteries and other equipment subsystems overcurrent overtemperature protection
Manufacturers to reduce costs or to a smaller selection of copper or aluminum wire wound, making the transformer winding temperature faster; when the secondary load circuit short circuit or high current occurs, the transformer will soon be over-temperatur
SMD type, lead-free, roll-reel packaging for automated assembly, used in high-density circuit boards, working current: 0 1-3 0A Operating Voltage :6-60V Working temperature: -40 ~ 85 ℃
