In a study of 196 patients at high risk for tamponade because of pericardial effusion more than 7 days after cardiac surgery, Meurin et al found that diclofenac was not effective in reducing the size of the effusion or in preventing late cardiac tamponade.
1 There are two major types of interference-suppression / AC line filter safety capacitors; namely, type X and type Y. The purpose of these capacitors is to reduce radio frequency interference and to ensure safety from shock and fire. In AC/DC (radios that do not use power transformers) radios where a line filter capacitor is connected between the hot and ground side of the power line, that capacitor is known as an across-the-line capacitor. 2  Across the line capacitors serve to keep RF noise disturbances from affecting the receiver.
Decoupling and by-pass capacitors are also used in any area of a circuit to reduce the overall impact of electrical noise. Coupling or DC Blocking Capacitors-Since capacitors have the ability to pass AC signals while blocking DC, they can be used to separate the AC and DC components of a signal.apacitor Safety. A few safety precautions should be taken with capacitors. As energy storage components, capacitors can store dangerous amounts of energy that can cause fatal electrical shocks and damage equipment even if the capacitor was disconnected from power for a considerable amount of time.
