Transient voltage If there is a possibility that the transient phenomenon (significantly high voltage applied in a short time) may occur or that a high voltage pulse may be applied, make sure to evaluate and check the characteristics of Metal (Oxide) ilm Resistors (hereafter called the Resistors) mounted on your product rather than only depending on the calculated power limit or steady-state conditions to complete the design or decide to use the Resistors. 2. The Resistors are covered with a special coating. Do not apply shock or vibration to them, or pinch them with long-nose pliers. Otherwise, the Resistors may be damaged. 3. Do not apply excessive tension to the lead-connected sections. hen bending the lead wire, do not apply excessive stress to the Resistors and provide the wire with a natural curvature. 4. Do not brush the Resistors during or after the cleaning process, which may be conducted after soldering. Otherwise, the coating film may be damaged.

8 Caution for Safety (Common precautions for ixed Resistors) hen using our products, no matter what sort of equipment they might be used for, be sure to make a written agreement on the specifications with us in advance. 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. efore 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 (automobile, train, vessel), traffic lights, medical equipment, aerospace equipment, electric 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 () recautions for use These products are designed and manufactured for general purpose and standard use in general electronic equip ment (e.g. V equipment, home electric appliances, office equipment, information and communication equipment) These products are not intended for use in the following special conditions. efore 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 2. In direct sunlight, outdoors, or in dust 3. In salty air or air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2 4. In an environment where strong static electricity or electromagnetic waves exist 5. In an environment where these products cause dew condensation 6. Sealing or coating of these products or a printed circuit board on which these products are mounted, with resin or other materials These products generate Joule heat when energized. Carefully position these products so that their heat will not affect the other components. Carefully position these products so that their temperatures will not exceed the category temperature range due to the effects of neighboring heat-generating components. Do not mount or place heat-generating components or inflammables, such as vinyl-coated wires, near these products. Note that non-cleaning solder, halogen-based highly active flux, or water-soluble flux may deteriorate the perfor mance or reliability of the products. Carefully select a flux cleaning agent for use after soldering. n unsuitable agent may deteriorate the performance or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to leave water residues. Otherwise, the insulation performance may be deteriorated. (2) recautions for storage The performance of these products, including the solderability, is guaranteed for a year from the date of arrival at your company, provided that they remain packed as they were when delivered and stored at a temperature of 5 C to 35 C and a relative humidity of 45 % to 85 %. Even within the above guarantee periods, do not store these products in the following conditions. Otherwise, their electrical performance and/or solderability may be deteriorated, and the packaging materials (e.g. taping materials) may be deformed or deteriorated, resulting in mounting failures.. In salty air or in air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2 2. In direct sunlight <ackage markings> ackage markings include the product number, quantity, and country of origin. In principle, the country of origin should be indicated in English. ER3
