Со вспышкой всего рынка резко увеличился и спрос на MLCC. Более того, рынок прогнозирует, что ситуация с дефицитом MLCC будет более серьезной.

В этом случае мы хотели бы предложить вам разместить заказ раньше, чтобы избежать каких-либо неудобств, связанных с пустым инвентарем. Добро пожаловать, чтобы связаться с нами для получения дополнительной помощи.

Com a demanda por surtos de MLCC TS18 e TS18H nos últimos meses, nosso capacitor mono, incluindo o tipo radial TS17R e axial TS17A, foi influenciado seriamente. Para uma melhor alocação dos materiais limitados, linhas de produção e forças de trabalho, temos que tomar algumas decisões importantes como abaixo:

1． Parar a produção e cotação do TS17A temporariamente;
2． Toda a oferta antiga da TS17R está a perder a invalidez e o preço seria marcado devido ao aumento do custo das matérias-primas;
3． Para as ordens TS17R, não aceitaremos mais as condições de pagamento, em vez disso, T / T completo com antecedência.

Para resumir em conclusão, nosso lead time da série TS17R seria muito mais longo por conta de nossa linha de produção sobrecarregada. E pior situação é que nós julgamos que seria ainda mais crítico com as crescentes encomendas. Se você tem uma demanda real e uma exigência estável, é melhor fazer o pedido por um ano inteiro ou sofrer um rápido aumento no custo de compra e um lead time mais longo insuportável.

Devido à recente demanda forte da MLCC, nossa empresa fez o melhor para atender clientes, mas ainda tem problemas de oferta. Sob esta situação, a nossa entrega será prolongada de 3 a 4 semanas para 7 ~ 19 semanas a partir do terceiro trimestre de 2017. Nossa equipe de vendas entrará em contato com sua empresa para explicar o programa específico. Desculpe-nos por qualquer inconveniente!

Suntan Technology and Rapid Electronics are delighted to announce a new partnership, which will see Rapid become a franchised distributor for Suntan’s extensive range of potentiometers, capacitors, varistors and diodes.

Rapid is one of the UK’s leading distributors of electronic components, cables and connectors, electrical products, parts and spares for high volume and bespoke industrial customers. Rapid will stock a comprehensive range of our components, with non-stock parts available on short lead times and the complete Suntan portfolio accessible on a high or low volume basis.

Richard Abbot of Rapid Electronics, said: “I am delighted to have signed this agreement with Suntan. We look forward to making Suntan’s high quality ranges available to Rapid customers, and working closely with Suntan over the coming months and years to deliver high service levels and competitive pricing on all Suntan components to our customers”.

Data shows that more and more people start using multi-layer ceramic capacitors/MLCC, and increasingly optimistic about their new circuit design applications. In the past five to ten years, MLCC and tantalum capacitor capacitance of unit volume has been increased 10 to 100 times as before, MLCC application areas have gradually expanded to previously dominated by the tantalum capacitor site. Currently, MLCC and tantalum capacitors is competing between 1.0 to 100uF market. Many circuit design found that the new generation of large capacitance MLCC can better meet their needs, and higher production level (currently producing about 600 billion, and tantalum capacitors for 25 billion). Moreover, manufacturers of basic metal electrode and technological improvements have greatly reduced the cost of MLCC, which also increased victory chips for MLCC occupation tantalum capacitor market.

And at present ceramics are most cost affective in small sizes. Very large ceramics are a bit of a challenge, especially in SMD.

Currently the large case Suntan offer is up to 2225/3030 at Voltage 500V is 0.68uF, at Voltage 1000V is 0.1uF.

The main voltage : 50V, 100V, 200V, 500V, 1KV, 2KV, 3KV, 4KV

Material : NPO, X7R, Y5V

Size case : 0402, 0603, 0805, 1206, 1210, 1808, 1812, 2220/2225, 3030

Effect of Frequency: Frequency affects both capacitance and dissipation factor..

The variation of impedance with frequency is an important consideration in the application of multilayer ceramic capacitors. Total impedance of the capacitor is the vector of the capacitive reactance, the inductive reactance, and the ESR. As frequency increases, the capacitive reactance decreases. However, the series inductance (L)  produces inductive reactance, which increases with frequency. At some frequency, the impedance ceases to be capacitive and becomes inductive. This point, at the bottom of the V-shaped impedance versus frequency curves, is the self-resonant frequency. At the self-resonant frequency, the reactance is zero, and the impedance consists of the ESR only.

Dipped Ceramic Capacitors. The simplest ceramic capacitor consists of a square or circular shaped ceramic with electrodes attached (see figure). The capacitance is given by 

where A is the area of the two plates,  is the dielectric permittivity of vacuum, Kd is the dielectric's dielectric constant and d is the distance between the two plates.http://www.capacitors.hk/Ceramic-Capacitors/

MLC capacitors are marvels of modern material science. Manufacturing MLC capacitors is considerably more complicated than manufacturing dipped ceramic capacitors. First, the base ceramic material is mixed with a binder and fashioned into thin sheets. Electrodes are painted onto one side of the sheets using a paint that consists of a liquid binder with fine metal particles in suspension. The metals that are used include gold, palladium, platinum, and silver alloys. The reason for using these metals is that when the base ceramic is fired, oxygen is required for the ceramic proper to form. If one uses a metal such as iron, for example, it would oxidize completely during the firing process.Precious metals do not have this problem, but is a major cost component of monolithic ceramic capacitors. However, recently some manufacturers have reported using nickel and copper for the electrodes. This promises to reduce the cost of the raw materials, but at the expense of more elaborate manufacturing processes.

Once the ink is dry, the sheets are stacked on top of each other. The painted electrodes are arranged so that alternate electrodes exit from opposite ends. The top and bottom most layers do not have painted electrodes. The laminated layers are then compressed and fired, which sinters them into one monolithic structure.

Next, the ends are terminated, often using silver. For leaded capacitors, wires are attached, and finally the capacitor is encapsulated in plastic and marked. In the case of chip capacitors, the silver end terminations are covered with tin to aid soldering. The whole capacitor may be covered with lacquer.
