Las Vegas sphere 16K immersive LED technology
Inside the Sphere in Las Vegas is a 15,000 m2 (160,000 ft2, 4 acres) 16K resolution wraparound LED screen with over 170 million pixels. It’s 240 feet high and wraps around the audience to create fully immersive visual effects. The entire visual content generation and control system is completely redundant to ensure uninterrupted entertainment. This […]
What are ZIF and LIF connectors and where are they used?
How low contact resistance is achieved can be a key differentiator between zero insertion force (ZIF) and low insertion force (LIF) connectors. Many LIF connectors have a low contact resistance of about 30 mΩ when mated without needing a locking mechanism. ZIF connectors generally require a locking mechanism to achieve low contact resistance and a […]
Surface-mount low-current circuit breaker doubles as a thermal cutoff
Bourns, Inc. announced its smallest surface mount mini-breaker TCO device. The Bourns Model SW mini-breaker has a 4.7 mm x 2.8 mm footprint with a height of just 0.94 mm. Designed to control abnormal, excessive temperature virtually instantaneously, up to rated limits, the Model SW mini-breaker is an optimal overtemperature protection solution for a wide range of applications that include […]
MOSFET package design improves safety in high-voltage circuits
Littelfuse, Inc. announced the launch of CPC3981Z, an 800 V, 100 mA, 45 Ohm, Small Power N-Channel Depletion Mode MOSFET. Compared to a standard SOT-223 package, this new product’s SOT-223-2L package features a removed middle pin. That increases the drain-gate pin spacing from 1.386 millimeters to more than 4 millimeters. The extended creepage distance is beneficial in […]
Boost/single-ended primary inductance converter (SEPIC) controller for various automotive LED applications
