V-CHIP ALUMINUM ELECTROLYTIC CAPACITORS 貼片式鋁電解電容器 GENERAL INFORMATION FOR APPLICATION The following precautions must be observed when using electrolytic capacitors. 1. Circuit Design (1) Please make sure that the environmental and mounting conditions to which the capacitor to be exposed are within the conditions specified in this catalogue. (2) Operating temperature and applied ripple must be within the specifications. ① The capacitors shall not be used in an ambient temperature which exceeds the operating temperature specified in the specification. ② Do not apply excessive current which exceeds the allowable ripple current. (3) Appropriate capacitors which comply with the life requirement of the products, should be selected when designing the circuit. (4) Aluminum electrolytic capacitors are polarized. Make sure that no reverse voltage or AC voltage is applied to the capacitors. Please use non-polarized capacitors for a circuit that can possibly see reserved polarity. Note: Even non-polarized capacitors cannot be used for AC voltage application. (5) For a circuit that repeats rapid charging/discharging of electricity, an appropriate capacitor that is capable of enduring such a condition must be used. Welding machines and photo flash are a few examples of products that contain such a circuit. For appropriate choice of capacitors for circuit that repeat rapid charging /discharging, please consult us. (6) Make sure that no excess voltage (that is higher than the rated voltage) is applied to the capacitor. ① Please pay attention so that the peak voltage, which is DC voltage overlapped by ripple current, should not exceed the rated voltage. ② In the case where more than two aluminum electrolytic capacitors are used in series, please make sure that applied voltage should be lower than rated voltage and the voltage should be applied to each capacitor equally using a balancing resistor in parallel with the capacitor. (7) Outer sleeve of the capacitor is not guaranteed as an electrical insulator. Do not use standard sleeve on a capacitor in applications that require electrical insulation. When the application requires special insulation, please contact our sales office for details. (8) Capacitors may fail if they are used under the following conditions: ① Environmental (climatic) conditions (a) Being exposed to water, high temperature & high humidity atmosphere, or condensation of moisture. (b) Being exposed to oil or an atmosphere that is filled with particles of oil. (c) Being exposed to salty water or an atmosphere that is filled with particles of salt. (d) In an atmosphere filled with toxic gases (such as hydrogen sulfide, sulfurous acid, nitrous acid, chlorine, bromine, methyl bromide, ammonia, etc.) (e) Being exposed to direct sunlight, ozone, ultraviolet ray, or radiation. (f) Being exposed to acidic or alkaline solutions. ② Severe vibration and physical shock conditions that exceed our specification. Vibration test condition: Vibration frequency range: 10～55～10HZ Sweep rate : 10～55～10HZ/minute Sweep method : logarithmic Amplitude or acceleration: 1.5mm (maximum acceleration is 10G) Direction of vibration : X, Y, Z direction Testing time : 2 hours per each direction Shock is not applicable normally. If a particular condition is required, please contact our sales office. (9) When designing a circuit board, please pay attention to the following: ① Have the hole spacing on the P.C. board match the lead spacing of the capacitor. ② There should not be any circuit pattern or circuit wire above the capacitor safety vent. ③ Unless otherwise specified, following clearance should be made above the pressure relief vent. Case Diameter Clearance Required φ6.3 to 16 2mm or more φ18 to 35 3mm or more φ40 or more 5mm or more ④ In case the vent side is placed toward P.C. board (such as end seal vented parts), make a corresponding hole on the P.C. board to release the gas when vent is operated. The hole should be made to match the capacitor vent position. (10) The main chemical solution of the electrolyte and the separator paper in the capacitor are combustible. The electrolyte is conductive. When it comes in contact with the P.C. board, there is a possibility of pattern or short circuit between the circuit pattern, which could result in smoking or fire. Do not locate any circuit pattern beneath the capacitor end seal. (11) Do not design a circuit board so that heat generating components are placed near an aluminum electrolytic capacitor or reverse M E S E T H C NOTE: All designs and specifications are for reference only and are subject to change without prior notice.
