The design and specifications in this catalog are subject to change without prior notice. • Do not use the products beyond the specifications described in this catalog. • This catalog explains the quality and performance of the products as individual components. Before use, check and evaluate their operations when installed in your products. • Install the following systems for a failsafe design to ensure safety if these products are to be used in equipment where a defect in these products may cause the loss of human life or other significant damage, such as damage to vehicles (au to mo bile, train, vessel), traffic lights, medical equipment, aerospace equipment, elec tric heating appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment. ✽ Systems equipped with a protection circuit and a protection device ✽ Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault Precautions for use 1. Operation range and environments 1 These products are designed and manufactured for general and stan dard use in general elec tron ic equipment (e.g. AV equipment, home electric applianc es, office equipment, information and com mu nication equipment) 2 These products are not intended for use in the following special conditions. Before using the products, carefully check the effects on their quality and performance, and determine whether or not they can be used. • In liquid, such as water, oil, chemicals, or organic solvent • In direct sunlight, outdoors, or in dust • In salty air or air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2 • In an environment where these products cause dew condensation 2. Handling 1 Do not bring magnets or magnetized materials close to the product. The influence of their magnetic field can change the inductance value. 2 Do not apply strong mechanical shocks by either dropping or collision with other parts. Excessive schock can damage the part. 3. Land pattern design 1 Please refer to the recommended land pattern for each type shown on the datasheet. 2 Avoid placing the chip inductor on any metal pattern except the recommended land pattern because a drop of Q and mutual conductance may occur. 3 In case of flow soldering, venting of soldering flux gases should be made for high density assemblies to get a good solder connection. 4 In case of reflow soldering, consider the layout because taller components close to chip inductor tend to block thermal conduction. 4. Mounting 1 In general, magnetic and electric characteristics of ferrite cores can be changed by applying excessively strong force. Placement force should not exceed 20 N. 2 Do not bend or twist the PWB after mounting the part. 5. Cleaning 1 Do not use acid or alkali agents. Some cleaning solvents may damage the part. Confirm by testing the reliability in advance of mass production. 2 If Ultrasonic cleaning is used, please confirm the reliability in advance. It is possible that combined resonance of component and PWB and cavitation can cause an abnormal vibration mode to exist causing damage. 6. Caution about applying excessive current The rated current is defined as the smaller value of either the current value when the inductance drops 10 % down from the initial point or the current value when the average temperature of coil inside rises 20 °C up from the initial point. Do not operate product over the specific max. current. Package markings include the product number, quantity, and country of origin. In principle, the country of origin should be indicated in English. Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
