Care Note :

Care note for storage

(1) The chip is characterized to moisture sensitivity component which is defined in level 2 base on J-STD-

020C, the storage and SMT condition need to be confirm operation environment.

(2) Chip resistor shall be stored in a room where temperature and humidity must be controlled.

(temperature 5 to 35℃, humidity < 60% RH) However, a humidity keep it low, as it is possible.

(3) Chip resistor shall be stored as direct sunshine doesn’t hit on it.

(4) Chip resistor shall be stored with no moisture, dust, a material that will make solderability inferior, and

a harmful gas (Chloridation hydrogen, sulfurous acid gas, and sulfuration hydrogen)

(5) According to the above three points, the components can be stored for at least one year. After opening

the packaging, the components must be processed within seven days.

Care note for operating and handling

(1) Protect the edge and coating of the sensors from mechanical stress.

(2) Avoid bending of printing circuit board (PCB) when cutting and fixing it on support body to reduce

mechanical stress on sensors.

(3) Sensor should be used within the condition of specification.

Note: When a voltage higher than specified value is loaded to the sensor, this may damage the sensor

material due to temperature rise.

(4) The loaded voltage should consult terminal temperature of the sensor according to the derating curve.

(5) When applying a high current exceeding suggested specification (pulse current, shock current) to the

sensor, it is necessary to re-evaluate the operating condition before using it in the system.
