www.DataSheet4U.com PolySwitch™ Resettable Device Short Form Catalog MAY 2005 www.circuitprotection.com www.DataSheet4U.com For over 20 years, Raychem Circuit Protection, a unit of Tyco Electronics, has pioneered the technology behind PolySwitch™ PPTC (Polymeric Positive Temperature Coefficient) devices. The use of PPTC devices as a variable resistor in circuit protection applications was first pioneered by Raychem several decades ago. They were first used to help protect nickel-cadmium battery packs against excessive discharge and are still being used in that application today. Raychem Circuit Protection PolySwitch devices are commonly called resettable devices to distinguish them from traditional one-shot fuses that work only once and then must be replaced—an expensive and inconvenient proposition. While the generic term for these devices is “resettable fuses”, technically they are not fuses but actually non-linear thermistors. Designed for use in a wide range of electronic devices, these thermistor-type devices limit the flow of dangerously high current during fault conditions. But unlike traditional fuses that work one time and must be replaced, Raychem Circuit Protection’s PPTC devices reset after the fault is cleared and power to the circuit is removed. This reduces service and repair costs, resulting in improved customer satisfaction and reduced warranty costs. To date, billions of PolySwitch products are used to help protect a wide range of electronic products in automotive, battery and portable electronics, computer and peripherals, consumer, industrial, and telecommunication markets. In addition, Raychem Circuit Protection continues to expand their circuit protection offerings with Telecom Fuses, ROV Radial-leaded Metal Oxide Varistors, SiBar™ Thyristor surge protectors, Raychem Gas Discharge Tubes for overvoltage protection, and most recently, Polymer electrostatic discharge (PESD) protection devices. Raychem Circuit Protection is recognized as a leader for operational excellence and customer service. A dedicated direct engineering sales force, world-wide manufacturing and design centers, and local engineering support help them to think, manage and share globally, yet act locally, to meet customer needs.
