Littelfuse's comprehensive universal port protection solutions protect your product design!
Whether in the automotive and consumer electronics we see in daily life, or in application areas such as data centers and industries, there are more and more universal ports, which greatly facilitates the operation of products. Friends who are familiar with port design know that port design is critical to the overall safety and reliability of the product. One of the important concerns is that various electrical protection measures need to be fully considered during the port design process to prevent potential hazards caused by lightning surges, inductive power surges, power crossover, electrical fast transients (EFT), electrostatic discharge (ESD) and short circuits.
For example, lightning surges can couple into industrial data lines, causing temporary or permanent damage to sensitive ICs. Lightning and power grid switching can cause surges. Electrostatic discharge can damage ICs through connectors. Wiring errors or insulation damage during assembly can expose cables to AC line voltages. Electrical fast transients can be caused by inductive load switches or "bouncing" of relay contacts.
Littelfuse offers a comprehensive range of general purpose port protection solutions for automotive, building automation, consumer electronics and industrial applications from common lightning surges, inductive power surges, power cross, electrical fast transients, electrostatic discharge, and short circuits caused by wire aging and installation.
Here are some typical application cases and protection devices:
Circuit protection solutions for power supplies and communication ports
Lightning, ESD and Power Fault Protection for PoE++
TVS Diode Arrays
The SC1004U-ULC-04UTG provides unidirectional ESD protection while maintaining signal integrity for the more challenging high-speed serial interfaces.
TVS Diodes - SMDJ Series
The SMDJ series is specifically designed to protect sensitive electronic equipment from voltage transients caused by lightning and other transient voltage events.
461 Series - TELELINK® Surge Protective Surface Mount Fuse
Littelfuse 461 Series TeleLink ® Surface Mount Surge Fuses provide overcurrent protection for a wide range of telecommunications equipment without the use of series resistors.
Low Rho SMD Series - PolySwitch PPTC for general electronic product overcurrent protection
Littelfuse Low Rho Surface Mount PPTC (Polymer Positive Temperature Coefficient) devices provide overcurrent protection for applications that require ultra-low internal resistance, ultra-low voltage drop, and automatic reset protection. This series of products can support the construction of smaller, lower-height, and higher-holding current devices compared to standard PPTCs . It has ultra-low internal resistance while continuing the high level of electrical characteristics and performance of standard PPTC products.
