Reference Specification Safety Standard Certified Metal Terminal Type Multilayer Ceramic Capacitors for Automotive in accordance with AEC-Q200 ( Type MF Safety standard certified ceramic capacitor of Class X1,Y2 ) Product specifications in this catalog are as of Aug.2019, and are subject to change or obsolescence without notice. Please consult the approval sheet before ordering.Please read rating and Cautions first. Reference only Caution Storage and Operation Conditions 1. The performance of chip monolithic ceramic capacitors may be affected by the storage conditions. 1-1. Store the capacitors in the following conditions:Room Temperature of +5C to +40C and a Relative Humidity of 20% to 70%. (1) Sunlight, dust, rapid temperature changes, corrosive gas atmosphere, or high temperature and humidity conditions during storage may affect solderability and packaging performance. Therefore, please maintain the storage temperature and humidity. Use the product within six months, as prolonged storage may cause oxidation of the electrodes. (2) Please confirm solderability before using after six months. Store the capacitors without opening the original bag. Even if the storage period is short, do not exceed the specified atmospheric conditions. 1-2. Corrosive gas can react with the termination(external) electrodes or lead wires of capacitors, and result in poor solderability. Do not store the capacitors in an atmosphere consisting of corrosive gas (e.g., hydrogen sulfide, sulfur dioxide, chlorine, ammonia gas, etc.). 1-3. Due to moisture condensation caused by rapid humidity changes, or the photochemical change caused by direct sunlight on the terminal electrodes and/or the resin/epoxy coatings, the solderability and electrical performance may deteriorate. Do not store capacitors under direct sunlight or in high humidity conditions. Rating 1. Temperature Dependent Characteristics 1. The electrical characteristics of a capacitor can change with temperature. 1-1. For capacitors having larger temperature dependency, the capacitance may change with temperature changes. The following actions are recommended in order to ensure suitable capacitance values. (1) Select a suitable capacitance for the operating temperature range. (2) The capacitance may change within the rated temperature. When you use a high dielectric constant type capacitor in a circuit that needs a tight (narrow) capacitance tolerance (e.g., a time-constant circuit), please carefully consider the temperature characteristics, and carefully confirm the various characteristics in actual use conditions and the actual system. 2. Measurement of Capacitance 1. Measure capacitance with the voltage and frequency specified in the product specifications. 1-1. The output voltage of the measuring equipment may decrease occasionally when capacitance is high. Please confirm whether a prescribed measured voltage is impressed to the capacitor. 1-2. The capacitance values of high dielectric constant type capacitors change depending on the AC voltage applied. Please consider the AC voltage characteristics when selecting a capacitor to be used in an AC circuit. 3. Applied Voltage 1. Do not apply a voltage to the capacitor that exceeds the rated voltage as called out in the specifications. 1-1. Applied voltage between the terminals of a capacitor shall be less than or equal to the rated voltage. (1) When AC voltage is superimposed on DC voltage, the zero-to-peak voltage shall not exceed the rated DC voltage. When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage. (2) Abnormal voltages (surge voltage, static electricity, pulse voltage, etc.) shall not exceed the rated DC voltage. Typical Voltage Applied to the DC Capacitor DC Voltage DC Voltage+AC AC Voltage Pulse Voltage EE EE 00 EE EE 00 00 00 (E: Maximum possible applied voltage.) 1-2. Influence of over voltage Over voltage that is applied to the capacitor may result in an electrical short circuit caused by the breakdown of the internal dielectric layers. The time duration until breakdown depends on the applied voltage and the ambient temperature. 2. Use a safety standard certified capacitor in a power supply input circuit (AC filter), as it is also necessary to consider the withstand voltage and impulse withstand voltage defined for each device. 1 / 22 EGKCA03
