PPTC Resettable Fuses are rated up to 60 Vdc and 3 A.

Press Release Summary:

PPTC Resettable Fuses are rated up to 60 Vdc and 3 A.

Nov 06, 2009 - Offered in 5 EIA/IECQ case sizes from 0805 to 2920, surface mount 0ZCx Series limits flow of dangerously high current during fault conditions to protect products from over-current surges and over-temperature faults. In event of fault, fuses reset themselves once power is removed, fault is corrected, and voltage is reapplied. RoHS-compliant, lead-free, and halogen-free, fuses are suited for consumer electronics such as PDAs, digital cameras, MP3 players, and video recorders.

Bel's Portfolio of PPTC Resettable Fuses Now Includes 5 Surface-Mountable Series

Press release date: Nov 03, 2009

Chips Optimized to Protect Circuits in Most Popular Consumer Electronic Products and Systems

Jersey City, NJ, November 3, 2009...Announced today by Bel Fuse Inc., a premier developer of fuses and magnetic-based solutions for high-speed networking and computer applications is the expansion of their 0ZCx Series of surface mountable Polymeric Positive Temperature Coefficient (PPTC) resettable fuses. The RoHS-compliant, lead-free and halogen-free Series features Bel's unique polymer formulation to ensure long-life performance and superior overcurrent protection in the broadest range of consumer electronics. Offered in five EIA/IECQ case sizes ranging from 0805 to 2920, the chip fuses are rated up to 60 VDC with current ratings up to 3A. Chips are specifically engineered to limit the flow of dangerously high current during fault conditions to protect products and systems from overcurrent surges and overtemperature faults. In the event of a fault, fuses reset themselves once power is removed, the fault is corrected, and the voltage is reapplied. Their resettable functionality, coupled with unparalleled reliability, makes Bel's 0ZCx Series the ideal alternative to traditional fuses and fusible links. Moreover, they facilitate the utmost in design flexibility and manufacturing efficiencies while enabling OEMs/ODMs to minimize repair, service, and warranty expenses. Materials meet UL-94V-0 requirements.

The 0ZCx Series is appropriate for use on high-density PC boards in a wide array of consumer electronics applications in which safety and reliability are critical factors. They are commonly specified for use in PDAs/digital cameras, MP3 players, video recorders, and set-top boxes. Parts are equally well suited for battery and port protection in mobile phones, port protection in game consoles, plug and play protection for PC motherboards and peripherals, USB peripherals, disk drives, and CD-ROMs.

Boasting a fast trip time and provided in an industry-standard 0805, 1206, 1210, 1812, or 2920 footprint, the 0ZCx Series feature hold current ratings from 50mA to 3A. PTC chips' operating temperature range is -40 degrees C to +85 degrees C.
