Raychem Circuit Protection, a business unit of Tyco Electronics, expanded its circuit protection portfolio with the introduction of its new series of RoHS-compliant PolySwitch miniSMDC and SMD terminal devices for the automotive industry.

The PolySwitch Polymeric Positive Temperature Coefficient (PPTC) devices help provide resettable overcurrent protection in applications where conserving board space is a critical design factor, including PCB traces, motors, harnesses, chargers, hands free applications and multimedia input ports.

The new circuit protection devices are characterized by their small size, and wide range of current and voltage options. These devices are available with voltage ratings ranging from 6V to 60V and hold current ratings ranging from 50mA to 2.6A. The SMD devices are available in standard 1206 to 3425 sizes, with smaller sizes coming soon.

"These devices will allow us to continue supporting the automotive market for years to come," said Ashfaque Ameen, product marketing manager, in a statement. "Additionally, the device's compliant status shows Raychem Circuit Protection's commitment to helping to protect both the environment and our customer's products."

The new PolySwitch devices are compatible with industry standard installation procedures, and are available in tape and reel packaging for compatibility with high-volume manufacturing. These new products are priced at 30 cents in quantities of 100,000 units/year.
