Don’t get burned about LED UV
Another myth busted: You needn’t worry about ultraviolet light coming from ordinary LED bulbs. We recently checked a batch of LED bulbs for the amount of blue light they gave off. This effort came in response to claims from some in the alternative medicine crowd that LED bulbs gave off inordinate amounts of unhealthy blue […]
Sager Electronics to stock 30-W single-port PoE injectors from Phihong
Sager Electronics is now stocking Phihong’s POEA30U 30W single-port PoE injector power supplies. The injectors are IEEE802.3at mid-spans that meet DOE VI efficiency regulations for external power supplies. They offer a 45.5mm x 140.2mm x 30mm 1.79″ x 5.52″ x 1.18″) footprint and provide 30W of power. These power supplies are ideal for use in a variety […]
Anti-surge chip resistors now come in 0402 size
The RPC Series from Stackpole is an anti-surge chip resistor with superior pulse handling performance compared to standard thick film chips. Stackpole has recently added an 0402 chip size rated at 0.2 W and featuring values from 1 Ω to 1 MΩ in tolerances as low as ±0.5% and TCR as low as ±100 ppm. […]
Heat sinks, Part 2: Available components
Part 1 of this FAQ looked at the basic issues associated with cooling and heat sinks. Part 2 focuses on the various heat sinks available. Q: Are heat sinks limited to a single component such as an IC? A: No, there are heat sinks which fit entire unit or chassis cool such as those which […]
Third-gen 0.18-u Bipolar-CMOS-DMOS process technology excels at driver, charger, dc-dc conversion IC fab
MagnaChip Semiconductor Corporation announced it now offers foundry customers its third generation 0.18 micron Bipolar-CMOS-DMOS (BCD) process technology. The technology is highly suitable for PMIC, DC-DC converters, battery charger ICs, protection ICs, motor driver ICs, LED driver ICs and audio amplifiers. The third generation 0.18 micron BCD process technology offers improved specific on-resistance (Rsp) of power LDMOS […]
Plug-and-play gate drivers provide reinforced isolation for 1200 V and 1700 V IGBT modules
Power Integrations announced a new plug-and-play gate driver for use with Infineon’s PrimePACK 3+ and Fuji-equivalent IGBT modules for 2-level and 3-level applications. The SCALE-2 2SP0430T2XX gate-driver board suits industrial, traction, UPS and renewable-energy applications, and provides reinforced isolation for 1200 V and 1700 V IGBT modules. Meeting IEC60664-1 and IEC61800-5-1 standards and available in versions […]
Tiny contactless current sensor minimizes power loss
ROHM announced the availability of the industry’s smallest contactless current sensor, the BM14270MUV-LB. It achieves minimum power loss (no heat generation) in an ultra-compact size, making it ideal for industrial equipment and consumer devices that detect operating conditions via current, including battery-driven drones, solar power systems, and servers in data centers requiring high power. In recent years, […]
Taking resistor technology beyond RoHS
By Stephen Oxley, Senior Engineer Applications and Marketing, TT Electronics Lead has long been recognized as a serious environmental hazard. It has a detrimental effect on the workings of the human central nervous system, and this is particularly acute when children are exposed to it. Based on the findings of scientific research conducted during the […]
