OPERATING PRECAUTIONS
Reliability can be affected adversely by improper storage environments and handling methods. Please observe the
following cautions.
Cautions for Storage
 Ensure that storage conditions comply with the standard temperature (5 to 35°C) and the standard relative humidity
(around 40 to 75%); avoid storage locations that experience extreme changes in temperature or humidity.
 Avoid locations where dust or harmful gases are present and avoid direct sunlight.
 Reinspect for rust on leads and solderability of products that have been stored for a long time.
Cautions for Testing and Handling
 When tests are carried out during inspection testing and other standard test periods, protect the products from power
surges from the testing products, shorts between the product pins, and wrong connections. In addition, avoid tests
exceeded ratings
Soldering
When soldering the products, please be sure to minimize the working time, within the following limits.
・Reflow Preheat ; 180°C / 90±30s
Heat ; 250°C / 10±1s (260°C peak ,2times)
・Soldering iron ; 380±10°C / 3.5±0.5s (1time)
Electrostatic Discharge
 When handling the products, the operator must be grounded. Grounded wrist straps worn should have at least 1MΩ of
resistance from the operator to ground to prevent shock hazard, and it should be placed near the operator.
 Workbenches where the products are handled should be grounded and be provided with conductive table and floor mats.
 When using measuring equipment such as a curve tracer, the equipment should be grounded.
 When soldering the products, the head of a soldering irons or the solder bath must be grounded in order to prevent leak
voltages generated by them from being applied to the products.
 The products should always be stored and transported in Sanken shipping containers or conductive containers, or be
wrapped in aluminum foil.
