More Information

Electrical Vehicle AC Chargers

Littelfuse provides a wide range of products that are suitable for Electric Vehicle AC Chargers. Although simpler in nature compared to DC chargers, AC charging stations safely deliver AC power from the electrical grid into the vehicle. Due to space and weight constraints in the vehicle, on-board chargers and AC charging stations are typically limited to lower amounts of power (22kW or less), which means charging time is slow – taking several hours. These systems also rely on a vehicle’s on-board charger to enable the conversion of AC power from the grid into DC power to charge the vehicle’s battery. It’s critical that proper measures are taken to safeguard both the charger and vehicle.

Indoor LED Lighting Circuit Protection

Littelfuse Indoor LED Lighting Circuit Protection ensures a long operating life, increased energy efficiency, and safety. LEDs can be damaged by voltage or current surges, and by extreme temperatures. Littelfuse circuit protection technology protects LED assemblies from potential damage. Important circuit protection technologies include metal-oxide varistors (MOVs), transient voltage suppression (TVS) diodes, and fuses.

Medical Equipment Solutions

Littelfuse Medical Equipment Solutions provide robust designed and quality components needed to help with reliable operating and equipment up-time. These solutions include ventilators, defibrillator, and ultrasounds. Littelfuse Medical Equipment Solutions are ideal for life support systems, patient care equipment, and patient monitoring systems.

PolySwitch Surface Mount Resettable PTCs

Littelfuse PolySwitch Surface-Mount (SMD) Resettable PTCs provide overcurrent protection for applications where space is at a premium, and resettable protection is desired. The components are reliable and capable of protecting computer and consumer electronics against temporary overcurrent faults. Package size varies from 0402 to 3425, while the current hold ranges from 50mA to 7.0A. The Littelfuse PolySwitch SMD product family is qualified to strict automotive standards (following the AECQ200 specification). As a result, these PTCs are suitable for protecting Electronic Control Units (ECUs) against damage from faults that would otherwise require costly, complete module replacement.

PolySwitch Resettable Devices

Littelfuse PolySwitch and POLY-FUSE Devices are Polymeric Positive Temperature Coefficient (PPTC) devices that offer a resettable overcurrent protection alternative, reducing warranty, service, and repair costs. PTCs increase resistance as temperature increases due to increased flow. The components are designed to limit unsafe currents while allowing constant safe current levels, resistance will “reset” automatically when the fault is removed, and temperature returns to safe levels. The ability of the PTCs to reset themselves after exposure to a fault current makes them ideal within circuits that are not easily accessible. PTCs are typically used as circuit protection in applications where sensitive components are at constant risk of damage from overcurrent conditions. The components are also ideal for situations where frequent overcurrent conditions occur or constant uptime is required. Littelfuse Resettable PTCs (PPTCs) are typically used in consumer electronics, power line, telecom, I/O port, process control and medical equipment protection applications.

Electrical Vehicle DC Fast Chargers

DC charging stations are designed to convert the electrical grid’s AC power into DC power that can then be fed directly into a vehicle’s battery system for fast charging – in 30 minutes or less. Because the conversion from AC to DC power is being done in the charging station, these units can provide higher levels of power (50kW to 350kW and beyond) to the vehicle compared to AC charging stations. Working with tens to hundreds of kilowatts of power, efficient conversion, reliability of the system, and user safety are critical.
