Rutronik extends portfolio with Yageo’s SMD and radial PPTC fuses  

Surface mount or radial design PPTC (polymeric positive temperature coefficient) fuses by Yageo are now available from Rutronik. The range is made up of fuses with varying maximum voltages that the application can withstand at rated current without damage whereby electrical resistance increases in case of overload due to self-heating to keep the current relatively small. Resettable fuses can trip several times because the component (after interrupting the circuit and cooling down) becomes low-resistance again and can continue to be used. The various specifications in the Yageo PPTC fuse series enables them to be used for smart meters, telecommunications, auxiliary power supply, security monitoring, industrial as well as the protection of USB and other connections. 

The surface mount variants offer resettable miniature over-current protection with a holding current Ihold of up to 7A and a maximum voltage of 24, 30, 48 or 60V. They have a fast response to fault current and a low profile allowing more space on the PCB. The SMD fuses are RoHS-compliant, lead and halogen-free. They are also certified to UL/CULE482628, RoHS2011/65/EU TUV B160696048001, and DIN EN 14582:2007. The fuses are also compatible with high-temperature soldering processes.

The radially wired, resettable fuses enable over-current protection with a holding current of up to 14A. This series is suitable for applications with higher operating voltages of 16, 30, 60, 130, 250 or 500V due to the high voltage over-voltage capability. These fuses also operate reliably at temperatures of -40 to +85 degrees C. They can be stored almost indefinitely at a room temperature of 30 degrees C and a maximum humidity of 85 per cent (MSL1 according to J-STD-020). The fuses have flame-retardant epoxy polymer insulation material which meets the requirements of UL94 V-0. They are also available in lead-free versions.

Rutronik Elektronische Bauelemente was founded in 1973 and is based in Ispringen, Germany. The distributor has more than 80 offices worldwide and logistics centres in Texas, USA, Shanghai, Singapore, and Hong Kong to support customers in Europe, Asia, and North America.
