A rectifier diode can sell for a few cents, and the industry around it is still substantial, which is the part that surprises people. The explanation is arithmetic rather than sentiment: a device that appears in almost every electronic product is bought in enormous quantities, and a few cents multiplied by a very large number … Read more
The demand that artificial intelligence places on a data centre is not really a demand for more electricity in the abstract; it is a demand for a great deal of power delivered to a small area, continuously, with a loss budget that has to be paid for twice — once as wasted electricity and once … Read more
A solar installation and a battery storage system both convert electricity, but they do it differently, and the difference explains most of what is inside them. A grid-tied solar inverter changes direct current from the panels into alternating current for the grid. A storage system has to do that in both directions, which means the … Read more
An electric vehicle report becomes misleading the moment three different numbers are put in the same sentence. Vehicle sales are counted in units, semiconductor content is counted in devices or in value per car, and the semiconductor market is counted in money. Each answers a different question, and a change in one does not imply … Read more
There is no single power semiconductor forecast for 2026, and that is the useful answer rather than an evasion. Demand for power devices follows four things you can actually check: how much equipment is being built, how much semiconductor content each unit contains, how much capacity exists to make the parts, and where the unsold … Read more
A normal component order arrives with four documents: the invoice, the packing list, a certificate of conformity or a compliance declaration, and the information that links the parts to a production lot. Everything else is either specific to the part — a test report, a qualification report, a handling instruction — or specific to your … Read more
A minimum order quantity is the smallest quantity a supplier will sell in one transaction, and a lead time is the delay between placing that order and receiving it. Both exist for the same reason: the cost of handling an order barely changes with its size, so a supplier with a fixed cost per order … Read more
You can catch most counterfeits with nothing more than your eyes, a bright light and a multimeter. Four checks do the work: compare the packaging against the manufacturer’s own photographs, read the laser marking under magnification, look the part number up in the manufacturer’s datasheet, and measure the part against what that datasheet says it … Read more
Soldering was one of the parts of electronics that had not changed much in decades, and lead was the reason. Removing lead raised the temperatures every assembly has to survive and introduced a reliability question that had been dormant for most of a century. Why lead was in solder at all Tin-lead solder is close … Read more
RoHS and REACH are two European regulations that appear side by side on almost every component declaration, and they are not two versions of the same thing. One restricts specific substances in electrical equipment; the other regulates chemicals generally, including those used in any product. Understanding the difference answers the practical question of which one … Read more
RoHS is a European restriction on hazardous substances in electrical and electronic equipment, and it is the reason lead vanished from solder. Its effect went far beyond Europe, because a manufacturer building one global product tends to build it to the strictest rule it faces rather than maintaining separate versions. The problem RoHS was written … Read more
Buying components safely is less about finding a cheap price and more about knowing what you are buying and from whom. The difference between a good purchase and a bad one is usually not the part itself but the traceability that comes with it, and that is decided before the order is placed rather than … Read more
Send the topology, current and voltage class. Good-Ark sales and application engineering will confirm the closest device, package and qualification status.
