quirements, and those used for producing LL grade capacitors must be specially selected. The design effort required for such capacitors affects both the case size and the price. Aluminum electrolytic capacitors for general applications are called "General-Purpose Grade" (GP) in IEC publications. 2.2 Applicable standards Systematized Classification of Aluminum Electrolytic Capacitors CHIP TYPE (105℃, LOW ESR, HIGH RELIABILITY) CHIP TYPE (FOR VIBRATION RESISTANCE) CHIP TYPE (HIGH TEMP., LOW ESR, HIGH RELIABILITY) CONDUCTIVE POLYMER SOLID ELECTROLYTE HV 105°C 10000h D5-12.5 HVK 125°C 6000h D5-12.5 HVX 135°C 4000h D6.3-10 HT 105 °C10000 h D6.3-12.5 HTK Sep 5, 2009. For a given value of capacitance, I would expect the ESR value to vary from manufacturer to manufacturer. BUT if for a given cap from a given manuf. and that say in the datasheet that the ESR should 1 Ω ± xx%, but you measure that. cap and it is substantially different. Then you would have to suspect that the cap is failing. Capacitor Performance Chart All are available factory direct or on the brand line cards of an international network of capacitor sales repsand stocking capacitor distributors. Select chart… Metallized Polyester Metallized Polyester Motor Capacitors Metallized Polyester High Voltage Polyester/ Foil Metallized Polyphenylene Sulfide The graphs in the datasheet apply only to the ESR of the output capacitor. So you are free to just use a regular 0.1uF X7R type ceramic capacitor. The ESR on the input capacitor can be as low as you like (and you will probably get better performance if it is lower). Also, the use of Tantalum capacitors on the output is just a recommendation. A We have released a Design Support Software "SimSurfing" where characteristic charts can be displayed, and characteristic data of multilayer ceramic capacitors (MLCC and lead type) can be downloaded. Not only ESR and ESL values, but also the impedance frequency characteristics and other characteristic data can be confirmed. ESR is frequency-dependent, temperature-dependent, and changes as components age. It is usually only an important consideration in selecting electrolytic capacitors. Constructing the capacitor. 'Wet' aluminium electrolytic capacitors have an anode plate comprising an electrochemically-etched aluminium foil, a dielectric formed as an oxide Low • Impedance(Low ESR) UU CF(Polymer) 31 • For Audio Equipment UK UQ 275 • High Reliability, Higher Capacitance Range UH UE 164 ALUMINUM ELECTROLYTIC CAPACITORS Type Contents Obsoleted Series New Series Page ALUMINIUM ELECTROLYTIC CAPACITORS Standardization Some of the series listed below have been removed from the catalog. By measuring it against set values we can approximate the health of a capacitor. tan δ also called dissipation factor, abbreviated DF or D. As shown in the formula of the image, it is the ESR divided by the reactance of the capacitor. Reactance is the resistance of a capacitor to a change in voltage. Ceramic Capacitors The most commonly used and produced capacitor The name comes from the material from which their dielectric is made. Small size both physically and capacitance-wise. Don't normally go up to 10µF even. Has lower ESR and leakage currents than electrolytic caps. Cheapest type. If you are a designer of electronic circuits then you must consider equivalent series resistance (ESR) as a figure of merit.
