Littelfuse Expands TVS Diode Array Line with New Series
Littelfuse, Inc. has introduced the SPxx-01WTG-C-HV Series (SPxx Series) of general purpose ESD Protection TVS Diode Arrays (SPA® Diodes). The SPxx Series extends previous improvements for protecting sensitive electronic devices from damage due to electrostatic discharge (ESD) and other overvoltage transients. These new “high-voltage” 0201-size components are well suited for safeguarding the data lines on […]
The circuit protection connection for wearables and the IoT
by JAMES COLBY, Littelfuse Circuit protection technologies and board layout strategies help promote safety, reliability and connectivity. There’s one down-side to wearable technology that is unlikely to show up in headlines about the IoT: Human bodies generate static electricity as they move. That static electricity can potentially harm the sensitive electronics that power IoT applications. […]
TVS diodes absorb 24 A during lightning strikes
Littelfuse, Inc., a manufacturer in circuit protection, has introduced two new product series, the SP4044 and SP4045 Series TVS Diode Arrays (SPA® Diodes), designed to protect sensitive electronics from destructive electrostatic discharges (ESD) and lightning-induced surge events. Low capacitance diodes are integrated with an additional zener diode to protect each I/O pin against ESD and high […]
ESD diode arrays optimized for USB circuits
Littelfuse, Inc. (NASDAQ:LFUS) introduced its PULSE-GUARD® PGB2 0201 Series Surface Mount Polymeric ESD Suppressors, which are the smallest size polymer composite electrostatic discharge (ESD) suppressors in the market. The new suppressors are designed to help protect a broad range of sensitive electronic equipment from ESD damage. The new PGB2 0201 Series suppresses fast-rising ESD transients […]
Fuses billed as smallest SMT ever for 120/240VAC inputs
Littelfuse, Inc. has introduced two new series of its popular NANO2® Subminiature Fuse, each of which provides surge tolerance and circuit protection against overload conditions for downstream components. Both feature highly compact surface mountable packages for high design flexibility in space-constrained applications; the SMT design supports higher placement speed and higher yields during product manufacturing. […]
Compact AEC-Q101-Qualified TVS Diode protects against load dumps
Littelfuse, Inc. has introduced the SLD Series TVS Diode for automotive and high reliability applications. This AEC-Q101 qualified TVS Diode is designed specifically to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events. It offers a 5000W (10/1000s) or 2200W (load dump) peak pulse power dissipation rating in […]
High-voltage fuses pop quick
Littelfuse, Inc. has introduced the 487 Series Fuse, the first fast-acting fuse from its 5x20mm fuse family with both 420V AC and 420V DC ratings. In contrast with existing fuse solutions that cannot meet high-voltage and short-circuit test requirements, the 487 Series protects telecom power supply units and datacenter server power applications where a high-voltage […]
IGBT Modules hit 1,700 V, 450 A
Littelfuse, Inc., the global leader in circuit protection, has expanded its line of IGBT Module Power Semiconductor products designed for motor control and inverter applications. IGBT Power Modules are available in a broader range of package designs, now including half-bridge, six-pack, and PIM modules in S, D, H, W, and WB packages, with ratings up […]
Compact fuse for high-wattage smart phones
Littelfuse, Inc. has introduced the compact 777 Series Fuse to provide protection for higher-wattage wall-mount chargers for battery-powered electronic equipment. Although chargers for earlier generations of mobile phones had relatively low wattage (typically about 5W), today’s highly compact chargers must often be able to handle 10-15W of power, which requires withstanding higher levels of current.
