Business Wire
Announced today by Bel Fuse Inc. (NASDAQ: BELFA)(NASDAQ: BELFB),
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.
