Tyco Announces New PPTC Device Offering Small Form Factor For High Density Circuit Board Designs

November 05, 2007 by Jeff Shepard

Tyco Electronics announced a new addition to its popular PolySwitch™ resettable PPTC (polymeric positive temperature coefficient) devices surface-mount product family. Useful for the latest generation of high frequency data ports, I/O ports and storage devices, the picoSMD035F device is claimed to offer circuit designers the smallest PPTC overcurrent protection device available for consumer and computer electronics.

The new 0805 (2012 mm) EIA compliant form factor of the picoSMD device consumes less than half the board space required by previous offerings, and is said to provide a significant advantage in space-constrained board designs.

Rated at 6V, the picoSMD035F device provides a hold current of 0.35A, a trip current of 0.75A and a maximum resistance of 1.4Ω. The device meets safety agency standards, is full-edge terminated with nickel-gold finish for superior solderability, and is RoHS compliant. Production quantities are now available in tape and reel packages.

The devices are priced as $0.30 each in 100k volume, with a delivery time of 6-8 weeks.
