New Energy Efficient Compact Cooling Fans

admin2 — Sun, 23 Oct 2011 23:03:42 +0000

Each year, handheld electronics such as smart phones are becoming more and more compact. These devices also require a cooling system to help keep their processors cool and running. Furthermore, compact fans stop the system from overheating and help extend their life. These compact cooling fans come in four different sizes 15 to 30mm × 15 to 30mm × 6 to 10mm. They are also energy efficient (rated at 0.3 to 1.68 W), due to the limited power source in some compact devices. As a result, this series of compact cooling fans not only delivers a competitive amount of airflow (0.44 to 3.1 CFM), but also consumes minimal power. These fans also are low noise from 19.3 to 39.1 dBA. For samples or more information, please send an email to MyFeedback@dee-inc.com, and be sure to include your contact information.

Surge Protection Made Easy for IEC Applications

admin2 — Sun, 25 Sep 2011 19:33:12 +0000

High performance lightning & surge protection products for all IEC applications. Today’s world is full of electronic products and devices that are susceptible to damage from overvoltage surges.

New Resettable Overcurrent Circuit Protection for High-Rate-Discharge Li-ion Battery Applications

admin2 — Sun, 26 Jun 2011 19:34:31 +0000

Useful for high-rate-discharge battery applications at ratings above 30VDC/30A such as cordless power tools, e-bikes, and back-up power supplies. This technology uses a new hybrid circuit protection approach that combines a bimetal protector in parallel with a polymeric positive temperature coefficient (PPTC) device. This integrated solution provides resettable overcurrent protection and utilizes the low resistance of the PPTC device to help prevent arcing in the bimetal protector at higher currents, while also heating the bimetal to keep it open and in a latched position. The device has a 36VDC/100A maximum rating, and a time-to-trip of under five seconds at 100A (at 25°C). The device’s hold current is 30A, and the initial resistance is under two mOhms.

Protection Device for USB Applications

admin2 — Fri, 18 Feb 2011 16:16:33 +0000

The integrated device helps provide complete circuit protection for electronics with USB ports, and meets suspend-mode power consumption requirements for USB 3.0. A major advantage of the USB 3.0 specification is the increased operating current it allows devices to consume (900mA vs 500mA in USB 2.0). As more and more mobile devices adopt the USB port as the primary charging interface, the need for higher charging current has increased, and shorter charge time has become an important consideration. These devices help provide coordinated protection against damage caused by overvoltage, overcurrent, and ESD transients in a single package. It combines high power-absorption capabilities with low Vz (Zener voltage), and low powerconsumption.
