Precautions in use 8.1 Storage (1) Resistor shall be stored in a room where temperature and humidity must be controlled. ( temperature 5 to 35 deg C, humidity 45 to 85 % RH ) However, humidity keep it low, as it is possible. (2) Resistor shall be stored as direct sunshine doesn't hit on it. (3) Resistor shall be stored with no moisture, dust, a material that will make solderbility inferior, and a harmful gas (hydrogen chloride, sulfurous acid gas, and hydrogen sulfide). (4) Resistor shall be stored with keeping the minimum package unit with uncivilized sealed (Keep the state of the taping). 8.2 Time limit to storage (1) The storage time limit of the product is reckoned on the day when the product was shipped by our company and made within one year. (2) Confirm solderbility beforehand when you use the one that the time limit was passed. 8.3 Chip mounting (1) When chip are mounted on the PC board, the protection coat of resistors must not be scratched. If it will be scratched, it will make performance for moisture inferior. (2) In case that resistor will be soldered by soldering iron, heating shall be done on the land, and soldering iron must not hit on the resistor itself. (3) In case that resin coating or resin seal will be made for a PC board after chip mounting, do washing and drying it enough before coating or sealing. If ion bear or moisture will be sealed in resin coating, it will make performance for moisture inferior sometimes. For resinous use, it is necessary to set up enough the curing conditions. As it get improper for the condition, change of a resistance value are large and are a case. (4) According to shape, material, and pressure of clamping in chip mounting machine, there is the case that crack will be appeared on resistor. Control a shock energy for clamping resistor under 7×10−４ J. With a shock energy around clamping that says here, it is suited to a potential energy, in case that iron block of 25g is dropped naturally to the resistor placed on iron plate for the height of 2.8mm. (5) The glue to fix a resistor on the PC board around chip mounting, it is needed high insulation resistance and great performance or moisture. And it is needed that these characteristics are not inferior in using temperature range and a hot spot temperature to be acting. 8.4 Using and Handling (1) It is necessary to investigate the performance and reliability enough when using under harsh environment. Especially, the performance of the product is occasionally damaged when using with the dewy state or ion material adhered. (2) It is necessary to protect the edge and protection coat of resistors from mechanical stress. (3) Handle with care when PC board is divided or fixed on support body, because bending of PC board after chip mounting will make mechanical stress for resistors. TITLE: Specification for Chip resistor RR1220 series SUSUMU CO.,LTD SPEC.NO: Rev. No. RR00-1097 0 14/14 (4) Resistors shall be used within rated range shown in specification. Especially, if voltage more than specified value will be loaded to resistor, there is a case it will make damage for machine because of temperature rise depending on generation of heat, and increase resistance value or breaks. (5) In case that resistor is loaded a rated voltage, it is necessary to confirms temperature of a resistor and to reduce a load power according to load reduction curve, because a temperature rise of a resistor depends on influence of heat from mounting density and neighboring element. (6) Observe Limiting element voltage and maximum overload voltage specified in each specification. (7) If there is a possibility that a large voltage (pulse voltage, shock voltage) charge to resistor, It is necessary that operating condition shall be set up before use, because performance of thin film resistor is affected by a large shock voltage. 8.5 Using and Handling Refer to EIAJ RCR-2121 -- Electronic Industries Association of Japan technological report "Fixed resistor directions guideline.” TITLE: Specification for Chip resistor RR1220 series SUSUMU CO.,LTD SPEC.NO: Rev.
