Please do not supply inverse voltage or excess voltage to this product. If applied, this p roduct may be damaged and electrically destroyed. ・ Please design your product not to be affected by stress of the resin due to heat shri nk. ・ It is effective to make the Vcc and GND line wide and short or to adopt multi -layer PCB for switching noise protection. In addition, please place a bypass capacitor near the sensor. 7-3 Storage condition ・ Recommended storage condi tions are listed below. Temperature : +5 to +30 oC Humidity : 70%(RH)% and lower *Desiccator storage or storage in N 2 atmosphere is recommended. ・ Allowable storage time of the product is one year from the date of delivery. Please take account of the storage conditions listed above. Please also use the product as soon as possible after opening the product packing to avoid the deterioration of solderability. ・ Please avoid the water, chemical solvent, or oil. ・ Please avoid the corrosive gas (Cl 2 H2S, NH 3 NO2, NO 3 etc.) ・ Please avoid the strong vibration or shock. 7-4 Mounting ・ Please mount this product under standard reflow condition. Otherwise this produc t may be damaged. ・ Please do not apply excessive load to the terminals. Also, please do not bend the ter minals. ・ Please do not apply excessive bending stress to the product by bending the PCB or by similar handling as it may change the sensor sensitivity.
