 Querido cliente,

 Por favor, observe que nosso preço do MLCC é realmente competitivo e o prazo de entrega também é muito melhor que o anterior. Temos uma ampla faixa de tensão, que vai de 16V a 2.000VDC, e capacitância de 0,5pF a 4,7uF.

Encontre o link abaixo para obter informações mais detalhadas e não hesite em nos contatar (sales@suntan.com.hk & info@suntan.com.hk) para perguntas.

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.

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/
