Connectors for electric vehicle (EV) charging are both standardized and changing. On one level, EV charging connectors are standardized based on today’s technology limitations. There are standards in major regional markets, including North America, Japan, the European Union, and China. But current charging technologies are power limited. This FAQ begins with a review of EV […]

SMD zero-ohm jumpers handle over 70 A
Zero-ohm jumpers are widely used in all types of electronic circuits for a wide range of markets and end products. They make circuitry routing easier and simplify manufacturability. However, jumper requirements for higher current levels frequently exceed the capability of general-purpose jumpers, and even some jumpers are classified by the manufacturer as “high current.” Stackpole’s […]

Thionyl Chloride batteries excel in asset tracking, high-power apps
Ultralife Corporation has extended its ER Generation X family of Lithium Thionyl Chloride (LiSOCl2) batteries for critical applications, with two new products added to the range of rugged, energy-dense batteries. The new additions are the low rate UHE-ER14250-X 1/2AA size bobbin cell for asset tracking and more, plus the high-rate UHR-ER18505-X A size spiral cell for […]
Four-terminal shunts provide precision current sensing
Low resistance values are important for high-efficiency current sensing because lower values mean less wasted power on the current sensing measurement itself. But sensing low resistance values accurately becomes challenging because of lead resistance errors. Using a four-terminal shunt resistor eliminates the detrimental effects of lead resistance on the current sensing measurement operation. The HCSK1216 provides […]
Eval board covers battery management in IoT apps
