New Miniature Fast-Reacting SMT PPTC’s
The MF-USMD family of SMT resettable fuses has a 1210mils footprint and is perfect when board space is at a premium. Bourns Multifuse®, Polymer PTC’s offer overcurrent protection for a variety of applications, including motherboards, add-on cards, disk drives, peripherals and hand-held devices. The MF-USMD family comes in a range of hold currents from 50 mA to 1.1 A and is suitable for most low voltage applications. The MF-USMD family has voltage ratings from 6 to 30 volts and trip times of less than 0.3 seconds (@ 23C and 8A). The 1210/3225 footprint is a 40% reduction in size from the MF-MSMD family (1814532 footprint). These devices have UL, CSA and TUV certification pending and are available in T&R packaging (EIA 481-1). MOQ’s are 3,000 pieces that start at @body.25 per piece.

SMT High Current 1812mils/4532mm Footprint PPTC’s
Bourns Multifuse®, introduces five new 1812mils SMT parts to the existing MF-MSMD family of PPTC resettable fuses. These parts extend the hold current range from 1.25, 1.50, 2.00 A and 2.6 A while maintaining the same 1814532 footprint, useful for high-density board applications. These parts are used in circuit protection designs for USB ports, Firewire ports, add on cards, disk drives and peripherals. The MF-MSMD family of PPTC’s has voltage ratings from 6V to 8V and has low internal resistances ranging from 30 mOhms to 60 mOhms. The higher current devices are using Bourns proprietary multi-layer technology to maintain the 1812 footprint while providing designers with greater flexibility. All devices are UL, CSA and TUV certified. Production reels are available in 1,500 piece increments and start at @body.28 per piece.

New Low Switching Temperature and Low Resistance Battery Overcurrent Protectors
Bourns Multifuse®, now offers a new line of battery strap protection devices, giving designers of Polymer Lithium and Lithium Ion battery packs greater choice and flexibility in their circuit designs. The new MF-VS family has trip temperatures of 85C and resistance values of 18 to 30 mOhms. The MF-VS family offers hold currents from 1.7A to 2.4A and can be produced with a variety of lead length options. The MF-VS family has full agency approval for UL, CSA and TUV. Production lot sizes begin at 500 pieces and can be bulk packaged or on T&R. Pricing starts at @body.25 per piece.

New High Surge Voltage Capable Devices for the Telecom Industry
Bourns Multifuse®, now offers a line of radial and SMT parts that can withstand the high surge voltages of today’s telecom industry. Introduced to accommodate the telecom market, the new products can withstand voltage spikes of up to 250V or higher under certain circumstances, and can be used in conjunction with an over-voltage protector, such as a Bourns TISP® product, to shield against lightning strikes, power induction, power cross and transmission line faults. The higher voltage families are used extensively in the Telecom industry for SLIC card, POTS, DSL and data line protection. The parts are available in production quantities in bulk and T&R packaging. Pricing starts at @body.45 per piece.
