All kits cost less than $100. The hottest gifts this year are RS-485 and CAN QSOP Isolator Evaluation Kits. Happy Holidays NVE will be closed Thursday and Friday, December 25 and 26, and Thursday, January 1. We wish our readers the best this holiday season, and a successful 2015. 5 kV Two-Channel Isolators   Two-Channel IsoLoop® IL711 / IL721 Isolators are now available in 5 kV isolation voltage / 1 kV Working Voltage versions. Two-channel parts are available either with one channel each direction or both channels the same direction. NVE 5 kV-rated “V-Series” Isolators have best-in-class high-voltage performance. Parts are 100% tested to a jolt-worthy 6 kVrms (8.5 kVpeak), and to 1000 Vrms Working Voltage per VDE 0884-10. All IsoLoop Isolators feature a revolutionary ceramic/polymer composite isolation barrier providing a remarkable 44000 year extrapolated life and barrier resistance of more than 1014 ohms.   V-Series specifications include:   • 5 kVrms isolation (1 minute) per UL 1577   • 1000 Working Voltage (line voltage) per VDE 0884-10   • -40°C to +125°C operating temperature   • >1014 ohm barrier resistance   • Wide-body packages with True 8 mm creepage   Applications include:   • Medical instruments (see example below)   • Smart-grid interfaces   • Motor drives   • Power supplies The new IL711VE and IL721VE are in stock for immediate delivery, along with many other 5 kV isolators, including four-channel isolators and isolated transceivers.

The IL721VE offers best-in-class 1000 Working Voltage (line voltage) per VDE 0884-10 (see story above). Unique 2.5 kV MSOP Isolators are also available for minimum board space were 5 kV isolation isn’t required.
