Varistors sport monitor outputs, integrated thermal protection to handle over voltages
TDK Corporation presents two new series of ThermoFuse varistors, which are equipped with monitor outputs and integrated thermal protective components for overvoltage protection. The MT25 series (B72225M*) currently covers a voltage range from 150 VRMS to 385 VRMS, and its maximum surge current capability is 20 kA at a pulse form of 8/20 µs, according to […]
SMD resettable fuses handle high temperatures
Bel Fuse announces their 0ZT Series of high-temperature SMD resettable PPTC fuses for automotive, ethernet, and other applications that require a high operating temperature range of -40°C to 125°C. The 0ZT Series include five different chip sizes: 0ZTF (2920), 0ZTG (1812), 0ZTH (1210), 0ZTJ (1206) and 0ZTK (0805). Bel’s 0ZT Series are small surface mountable, […]
LED drivers in SOT1118D package features side-wettable flanks
Nexperia announced a new range of LED drivers in the space-saving DFN2020D-6 (SOT1118D) package. This case style features side-wettable flanks (SWF) which facilitate the use of AOI (automated optical inspection), and improve reliability. This is the first time LED drivers have been available in this beneficial package. The new leadless devices join Nexperia’s wide range of LED […]
Compact broadband infrared LED enables mobile spectroscopy
The most important aspect of infrared light sources for near-infrared spectroscopy is to cover as broad a wavelength range of emitted light as possible. The larger this range, the more objects that can be analyzed. In order to determine ingredients or water content, the target object is illuminated with infrared light of a wide wavelength […]
LED driver ICs handle TV backlighting
MagnaChip Semiconductor Corporation announced the launch of two new LED Driver ICs for UHD TV BLU (Back Light Unit). The two new models are 1-channel and 2-channel products developed for mid-range UHD TVs. An essential component of LED display panels, a BLU LED Driver IC is a power semiconductor device that delivers consistent lighting across […]
Shedding light on how much UV-C you need for disinfection
The idea of using UV-C light to kill the COVID-19 virus by disrupting its RNA has captured the imagination of many in the technical community. Unfortunately, important application details about factors such as necessary exposure time and intensity levels may be hard to discern, particularly for those who are new to the technology. A complicating […]
Latest connected car feature: Germicidal lights
Leland Teschler, Executive editor lteschler@wtwhmedia.com On Twitter @ DW_LeeTeschler A year ago, if your cocktail party conversations had included the idea of adding germicidal lights to a connected car, you probably would have elicited facial expressions suggesting you’d lost your mind. Today, the same idea would be more likely to engender a lot of head […]
LED drivers target automotive apps with wide programmable frequency operation, spread-spectrum clock
The TS19501 single-channel, dimmable LED driver targeting high-brightness automotive applications is well suited for virtually every automotive LED application: high and low beam headlights; daytime running lights; turn indicators; position indicator lights; fog lights; ATV and four-wheel drive high-brightness lamps. The IC is also offered in a version ideal for a wide range of non-automotive […]
It may become easier to disinfect with UV-C LEDs
UV radiation in the 200 to 300-nm range (dubbed the UV-C range) can destroy viruses, including the coronavirus. Problem is, doing so requires UV radiation sources putting out sufficiently high doses of UV light. That typically means using a relatively expensive mercury gas discharge lamp. It’s possible to find sources employing LEDs that put out […]
