Taping Quantity：3000 pieces per 7”reel Caution Of Handling Limitation of Applications Please contact us before using our products for the applications listed below which require especially high reliability for the prevention of defects, which might directly cause damage to the third party’s life, body or property. (1) Aircraft equipment (2) Aerospace equipment (3) Undersea equipment (4) Medical equipment (5) Disaster prevention / crime prevention equipment (6) Traffic signal equipment (7) Transportation equipment (vehicles, trains, ships, etc.) (8) Applications of similar complexity and /or reliability requirements to the applications listed in the above. Storage Condition (1) Products should be used in 6 months from the day of WALSIN outgoing inspection, which can be confirmed. (2) Storage environment condition. Products should be storage in the warehouse on the following conditions. Temperature : -10 to +40°C Humidity : 30 to 70% relative humidity Don’t keep products in corrosive gases such as sulfur. Chlorine gas or acid or it may cause oxidization of electrode, resulting in poor solderability. Products should be storage on the palette for the prevention of the influence from humidity, dust and son on. Products should be storage in the warehouse without heat shock, vibration, direct sunlight and so on. Products should be storage under the airtight packaged condition. Important Notes (1) This device should not be used in any type of fluid such as water, oil, organic solvent, etc. (2) Cleaning agent isopropyl alcohol and ethyl alcohol can be used. (3) As rapid temperature change for cleaning after reflow soldering might be a cause of degradation or destruction, clean this component after confirming that temperature of this component goes down to room temperature. (4) As ultrasonic vibration might be a cause of degradation or destruction, do not use ultrasonic cleaning. (5) This device follows JEDEC standards for moisture classifications. The following this device is classified as Moisture Sensitive Level 3 This device is moisture sensitive and need to be handled within proper MSL 3 guidelines to avoid damage from moisture absorption and exposure to solder reflow temperatures that can result in yield and reliability degradation (6) This is an Electrostatic Sensitive Device. Please avoid static voltage during operation and storage. (7) Sudden change of temperature shall be avoided, deterioration of the characteristics can occur. (8) If any malfunction due to designing or manufacturing which is out of specification occurs within one year after the products have been delivered, the maker should exchange the defective products.
