Technical Specifications
| Item | Description |
|---|---|
| Limited Applications | Designed for electronic circuits such as audio-visual equipment, home appliances, computers and other office equipment, optical equipment, measuring equipment. |
| High Reliability & Safety Requirements | If incorrect operation of this product may cause harm to human life or property, delivery specifications suited to the use separately need to be exchanged. |
| Intellectual Property Rights and Licenses | Technical information provides examples of products, typical operations, and application circuits. No guarantee of non-infringement of third-party intellectual property rights is provided, nor is any license, right, or interest granted. |
| Specification Guarantee | Guarantees the quality and performance of the product as individual components. Durability differs depending on the environment and conditions of usage. Compatibility with actual conditions when installed in products must be checked and evaluated before use. Immediately inform if safety requirements cannot be satisfied in technical examination. Do not use products beyond the specifications described in this document. |
| Application to Products Where Safety is Regarded as Important | Install protection circuits and redundant circuits for failsafe design if products are used in equipment where a defect may cause loss of human life or other significant damage (e.g., vehicles, medical equipment, aerospace equipment). |
| Conditions of Use | Products are designed and manufactured for general purpose and standard use in general electronic equipment. Not intended for use in liquid (water, oil, chemicals), direct sunlight, outdoors, dusty environments, vapor (dew condensation, water of resistive element, water leakage, salty air, air with high concentration of corrosive gas like Cl, H2S, NH3, SO2, or NOx), environments with strong static electricity or electromagnetic waves, near heat-generating components or inflammables, sealing or coating with resin, using solvent/water/water-soluble cleaner for flux cleaning after soldering, atmosphere with stray acid or alkaline, or atmosphere with excessive vibration and shock. Arrange circuit design for preventing impulse or transitional voltage. Do not apply voltage exceeding the full-rated voltage when capacitors receive impulse voltage. |
| Electrolyte Solution Usage | Misuse can result in rapid deterioration of characteristics and functions. Electrolyte leakage damages printed circuits and affects performance. |
| Operating Temperature and Frequency Effects | Electrical characteristics are likely to change due to variation in temperature and/or frequency. At higher temperatures, leakage current and capacitance increase while ESR decreases. At lower temperatures, leakage current and capacitance decrease while ESR increases. At higher frequencies, capacitance and impedance decrease while tan increases. At lower frequencies, heat generated by ripple current will rise due to an increase in ESR. |
| Operating Temperature and Life Expectancy | Expected life is affected by operating temperature. Each 10C reduction in temperature will double the expected life. Use capacitors at the lowest possible temperature below the upper category temperature. Exceeding upper category temperatures will result in rapid deterioration and irreversible damage. Check for maximum capacitor operating temperatures including ambient temperature, internal capacitor temperature rise due to ripple current, and effects of radiated heat. Avoid placing components that could conduct heat to the capacitor. Formula for calculating expected life at lower operating temperatures: L = L_rated * 2^((T_rated - T_actual) / 10). Using the capacitor beyond the estimated lifetime will result in short circuit, electrolyte leak, vent open, and large deterioration of characteristics. Lifetime cannot go above 10 years due to aging of sealing rubber. |
