Usage & Installation Notes
This is an archived article used for reference purposes. Some content may be outdated or missing.
- Do not apply a voltage exceeding the capacitor's voltage rating. To do so can shorten the life of the capacitor or even destroy it. When using the cap with AC voltage superimposed on DC, be sure that the peak value of AC when added to DC does not exceed the cap's rating. There is no surge or overvoltage tolerance assumed or warrantied.
- Do not apply excessive force to the lead wires.MultiCapsTM will withstand a three-pound maximum steady pull applied axially or radially for one minute, or one pound for one cycle. Applying excessive force to the leads will break them, sometimes internally, affecting the performance.
- Do not overheat the capacitor. The layout, size, shape, selection of components, and mechanical and enclosure design, together with the complex thermal interaction of the various parts of the circuit and nearby equipment, are intimately linked to thermal performance and long-term reliability. Measure the heat at the capacitor surface in the working environment. See the temperature specifications for each series.
- Use proper soldering techniques. If the soldering iron is placed too close to the capacitor's body or the soldering temperature is too high, you may damage the electrical insulation or alter the cap's characteristics. Typical soldering-tip temperatures are from 280 to 390 degrees C (540 - 735 degrees F). Solder assembly or part within 1 second (+/- 1/4 sec). In dip or wave soldering, leads should be dipped in solder of 260 degrees F or less for three seconds or less.
- Use the proper solvent. Halogenated hydrocarbon cleaning solvents can contaminate capacitors. Chlorinated solvents can damage the insulation or the seals. We do not guarantee any solvent, but the following are normally considered safe: methyl alcohol; xylene; ethyl alcohol; alconox (water soluble); propyl alcohol; butyl alcohol.
- Do not short the leads to discharge a capacitor without current limiting. Without current limiting, discharging a capacitor into itself will result in very high currents. MultiCapsTM appear, when discharged, as a dead short-circuit and have too little ESR to limit charging inrush current. We consider overvoltage surges and overcurrent surges (i.e., shorting of charged caps) as abuses of the capacitor.
- Keep lead lengths as short as possible for good high-frequency performance.
