U.S. manufacturers in the post-World War II also actively develop passive components, the two passive leading Vishay and Kimei through a number of large mergers and acquisitions, the success of the field on the top.
South Korea, Samsung in 1988 developed ultra-small MLCC, until 2007 began to MLCC for the significant expansion of production, from 20 billion in a single month to expand production to 48 billion in 2011, and in 2015 reached 58.8 billion / month, market share as high as 20%, and, Samsung does not hesitate to suppress gross margins means to seize the market.
Taiwan's passive components market is showing a pattern of domination, the strength of each manufacturer is balanced. Although the mainland side is mainly in the low-end products, but also emerged a number of high-quality manufacturers.
Rise, the overall delivery time of 3-6 months
Several major Japanese manufacturers in recent years gradually discontinued production of medium and high capacity MLCC, switching to more lucrative automotive products, resulting in a huge supply and demand gap in the field of 3C consumer electronics.
In terms of delivery, Samsung Electronics own MLCC inventory is now water tight, its subsidiary Samsung Electro-Mechanics has been in Busan, the Philippines and China's Tianjin factory to fully start the expansion of production, the overall delivery time of 3-6 months.
In terms of price, ceramic powder, electrode metal and packaging materials and other upstream material costs, each passive component manufacturers have raised product prices. The following is the timeline for each manufacturer to increase product prices:
October 2016, a number of agents received the National Giant's price adjustment notice, its most popular RC series of thick film resistors across the board price increase: 0201 price increase of 5%, 0603 price increase of 5%, 0805-1026 price increase of 3%, and its delivery time is generally lengthened to 8-10 weeks, close to doubling the extension of the period.
On February 25, 2017, Taiwan Hou Sheng issued an announcement to increase the price of some resistor products: due to the rising cost of raw materials, manpower and business operations, in order to cope with the trend of the industry, the Hou Sheng Group since March 1, 0603 (including) above the size of the chip resistor CHIP-R in the current selling price of the basis of the price rise of about 10%, the specific to the quotation.
April 20, 2017, Apple MLCC and R-Chip products supplier, the world's No. 1 resistor manufacturer and the world's No. 3 wave passive component manufacturer Taiwan National Giant to agents and customers to send a connotation to announce that the wafer resistor R-CHIP and wafer capacitor MLCC price adjustment.
April 21, 2017, China's largest chip resistor manufacturer Fenghua Hi-Tech sent a price increase notice of chip resistor products to customers.
June 1, 2017, TDK issued a notice to agents MLCC began to increase prices, the Japanese factory has been successful price increases and popular items rose by 5% -8%.
June 19, 2017, the National Giant notified MLCC price increases of 15%-30%, delivery time from 6 weeks to 24 weeks.
July 12, 2017, the world's second-largest resistor manufacturer, Taiwan's Daini Technology (Suzhou) factory issued a price increase notice: the various costs (including) freight and labor costs continue to increase the pressure, with immediate effect, suspended 0603-1206 chip resistor products to receive orders, to review the selling price before resuming orders.
What products are passive components? What is the difference between passive components and active parts?
Passive components are passive devices, active components are active devices, the so-called source refers to the "voltage source", "current source" and so on.
Generally speaking, passive components do not need to be connected to the power supply to operate, and can generate the function of regulating current and voltage, storing static electricity, preventing electromagnetic interference, and filtering current impurities. Compared to active components, passive components do not change resistance and impedance when the voltage changes.
Another way of saying this is that the components that utilize their electrical characteristics under bias voltage conditions are active components, while passive components should be components that do not change their electrical characteristics because of the change in bias voltage.
Active component: A component in a circuit assembly that performs data computation and processing. Including a variety of chips, such as semiconductor components in the transistor, integrated circuits, video tubes and displays are active components, mainly diode, BJT, MOSFETs and so on.
