Common-mode chip inductors suppress noise in high-temperature electronics
Bourns, Inc. introduced a new CANbus Common Mode Chip Inductor series. The new AEC-Q200 compliant inductors feature a ferrite core with a bifilar-wound construction that provides high impedance over a broad frequency range to suppress unwanted incoming or outgoing EMI signals. Offered in a compact form factor, the SRF4530A series features a wide operating temperature range from –55 to […]
Eval board carries 400-W Energy Star 6.1 supply circuit
STMicroelectronics’ EVL400W-EUPL7 evaluation board delivers a ready-to-use 400-Watt power-supply solution that meets today’s toughest eco-design norms. The board leverages innovative features of ST’s L4984D current-mode PFC controller and L6699 resonant half-bridge controller to maximize energy efficiency in multiple operating modes. Full-load efficiency is over 93% at 230VAC and over 91% at 110VAC, with no-load mains consumption of […]
Protecting autonomous vehicle control circuits
The subsystems that make up an autonomous vehicle should be bullet-proof when it comes to electrical interference and transients. James Colby, Prasad Tawade Littelfuse, Inc. Those who follow autonomous vehicle technology are usually well aware of its benefits. But the safety and convenience autonomous vehicles offer can only come if the vehicle electronics is reliable […]
Lithium-ion coin cells operate up to 105°C
NGK INSULATORS (hereinafter “NGK”) has raised the maximum operating temperature of its coin-type “EnerCera Coin” (part of the “EnerCera” series) battery up to 105°C. Sample shipments are currently underway, with mass production scheduled to begin in September 2020.
