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.

Smart Thermostat Solutions

Littelfuse Smart Thermostat Solutions components allow designers to implement Internet of Things (IoT) solutions to boost energy efficiency and monitor energy usage. Littelfuse Smart Thermostat solutions complement other Smart Building features, including safety and security systems.

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.

2920L PolySwitch® Resettable Fuses

Littelfuse 2920L PolySwitch® Resettable Fuses provide overcurrent protection for medium-voltage applications that require resettable protection. These polymeric positive temperature coefficient (PPTC) devices feature high voltage, a low profile, and a fast response to fault currents. The 2920L resettable fuses operate at -40°C to +85°C temperature range. Typical applications include IEEE 1394 port protection, powered ethernet port protection (IEEE 802.3 af), automotive electronic control module protection and low-voltage telecom equipment protection.
