DC link, energy storage, and pulse power capacitors
The first article in this three-part FAQ series reviewed safety capacitors (sometimes called high-frequency bypass capacitors), primarily for filtering electromagnetic interference (EMI) on the input of mains-connected power converters such as power supplies, battery chargers, and motor drives. This FAQ moves deeper inside the various types of power converters and will consider DC link capacitors, […]
Switch-mode driver/controller powers LED light engines
Innovations in Optics, Inc. introduces the Model 5000H switched-mode LED Driver/Controller for powering its patented and patent-pending High-Power LED Light Engines. It can also be used with third party LED illuminators as a constant current, DC to DC driver/controller. The 5000H LED Driver provides constant current in continuous or pulsed mode for LED arrays connected […]
n-channel MOSFET saves space, increases power density
Vishay Intertechnology, Inc. introduced a new 200 V n-channel MOSFET that offers industry-low typical on-resistance of 61 mΩ at 10 V in the 3.3 mm by 3.3 mm thermally enhanced PowerPAK 1212-8S package, in addition to improved on-resistance times gate charge — a critical figure of merit (FOM) for MOSFETs used in switching applications […]
Compact broadband infrared LED lightens mobile spectroscopy
Osram Opto Semiconductors announced its Oslon P1616 SFH 4737, the world’s smallest broadband infrared LED for spectroscopy applications, which will enable consumers to make more educated buying decisions by truly understanding the make-up and quality of what they are purchasing. The new Oslon LED, its unprecedented broad wavelength range, and 3x improvement in energy efficiency […]
Safety capacitors for EMI filtering and voltage isolation
This is the first article in a three-part FAQ series on capacitors used in power-handling applications. This article will consider safety capacitors for filtering electromagnetic interference (EMI, also called radio frequency interference, RFI) on ac power lines, for antenna coupling, and for providing voltage isolation in DC/DC converters. Part two will look into “DC link, […]
Zero-cross detection IC optimized for appliance power supplies
ROHM announces the availability of BM1ZxxxFJ, an integrated zero cross detection IC series, optimized for home appliances such as vacuum cleaners, washing machines, and air conditioners. The rising demand for smart appliances and IoT applications has added communication functionality (i.e. Wi-Fi) to home appliances. As it is necessary for such devices to always be ON to […]
SMD power inductors handle high temperatures, high currents
Sumida continues the expansion of its AEC-Q200 qualified SMD inductors with the introduction of the CDEP13D**/T150 line. Consisting of ten standard types and ten high-power types, the new devices offer a combination of four key benefits, when compared to many other inductors.
