Today’s data centers must handle the rapid rise in data volume from millions of devices that make up the Internet of Things (IoT). With increasing data traffic comes a greater demand for power, which generates more heat and requires more energy for the environmental controls that keep computing and networking equipment such as servers, blade servers, and edge servers operating reliably. Littelfuse data center solutions help operators manage demand increases and improve energy efficiency by protecting equipment against electrical hazards and overstress, controlling power quality, and sensing dangerous thermal events..
Affordably maintaining optimal temperatures in data centers for data reliability and operational cost savings.
Ensuring power supply system redundancy to prevent outages and data loss for mission-critical servers.
Avoiding data breaches that risk the unintentional sharing of sensitive business and personal information.
Supporting the success of today’s data centers means innovating to deliver solutions for evolving needs. Our broad product portfolio allows us to provide an unmatched, system-level perspective for protection throughout your data center facilities, from the equipment to the building infrastructure.
Often referred to as servers, edge servers, or blade servers, the computing equipment provides access to specific functions, services, or applications to other connected devices.

A multinational hyperscale company faced the challenge that many engineers today face: the need to do more with the same amount of space, or in some cases, less. In this case, the amount of power supplied by the data center rack power supply had increased, but the space allowed for the power supply remained the same. They needed overcurrent protection in a small, compact form factor that could be mounted to a circuit board. The TLS110.TXLSE Telecommunications Fuse allowed the power supply unit to meet the size requirement and provided reliable circuit protection.
