Capacitor Applications

Friday, 29. July 2011 9:36

Capacitor is a basic storage device to store electrical charges and release it as it is required by the circuit. Capacitors are widely used in electronic circuits to perform variety of tasks, such as smoothing, filtering, bypassing etc….
One type of capacitor may not be suitable for all applications. Ceramic capacitors are generally superior than other types and therefore can be used in a vast ranges of application. The following is the typical capacitor applications in electronic industries:
DC blocking capacitor: In this application the capacitor blocks the passage of DC current (after completely charged) and yet allows the AC to pass at certain portion of a circuit.
Capacitor as a filter: Capacitors are the main elements of filters. There are several types of filters that are used in electronic circuits, such as LPF (Low Pass Filter), HPF(high Pass Filter), BPF (Band Pass Filter), etc….
Since the reactance of the capacitor is inversely related to the frequency, therefore it can be used to increase or decrease the impedance of the circuit at certain frequencies and therefore does the filteration job.
Capacitor as a discharge unit: Capacitors used as a charging unit and the release of the charge (discharge energy) is used for triggering, ignition, and in high scale as a power source.
By Pass capacitor: The reactance of capacitor decreases as the frequency increases. Therefore in certain application it is used in parallel with other components to bypass it at a specified frequency.
Coupling capacitor: The ability of capacitor to pass AC signal, allows it to couple a section of an electronic circuit to another circuit.
Decoupling capacitor: In high speed electronic logic switching causes draw of significant amount of current which in turn would cause disturbance in the logic voltage level. Decoupling capacitor is typically located very close to the IC output and serves as a local energy source to provide the needed extra current and therefore minimizes the noise and disturbances to the logic signal.
Snubber capacitor: In some application, relays or SCR (Silicon controlled rectifier) are to drive a high inductance loads. In these circumstances, when the relay or the SCR opens, a major transient voltage could be induced in the contact of the relay or across the junction of SCR, which in turn either shows as an arc on the relay contacts or may damage the internal SCR junction. Therefore snubber capacitor is used to limit the high voltage transient across the circuit.
There are also other applications such as Tuned circuits, signal processing, etc…

Japanese semiconductor will resume in production chain in late August

Thursday, 28. July 2011 7:55

Since disruptions of local semiconductor production chain  in Japan caused by 311 earthquake, after the restructuring for about four months , the capacity since July have been fully restored to the level before the earthquake, including 12-inch silicon wafer, BT resin , wafer polishing liquid solder mask (SolderMask), etc., have begun full production supply, the semiconductor manufacturing chain is expected to return to normal operation in late August.But, because of continous summer power rationing problem in Kanto and Northeast, the lead time of semiconductors and electronic products is still longer about 3-5 weeks than than the ones before the earthquake.
As the earthquake leads to the supply disruption of key raw material of Japan’s semiconductor market, including TSMC, UMC, King Master, Southern Electric, ASE, SPIL and other businesses, although they stays over on inventory , but still affect monthly revenue of about 2-5% range increase in April and May.As Japan’s local technology industry has faster recovery than expected, including the BT resin, ultra-pure hydrogen peroxide with a semiconductor, wafer polishing liquid, solder mask, and other key chemical raw materials, have been resumed to be completed in June, 12-inch silicon wafer also returns to the level in July  before the earthquake. It is pointed out earthquake did cause the negative effects of insufficient supply , but because of the weak demand in end-market in May and June, which gives the original tight supply chain the opportunities of breath. Subsequently proved, many semiconductor plants were overbooking in the second quarter,but the end demand does not be kept up. Although the production affected by the earthquake in Japan has been resumed , but Japan still face limited local power problems.In other words, Japan’s semiconductor production capacity has been recoveried to the level before the earthquake in the third quarter, but the actual output is still affected by the problem of limited power, so the industry believes that the lead time of semiconductors and electronic products is still longer in the third quarter which is longer about 3-5 weeks.
