Sensing resistance in air R0 is measured under controlled ambient conditions, i.e. synthetic air at 23 5C and 50 10% RH. Sampling test. 2. Sensitivity factor is defined as Rs in air divided by Rs at 60 ppm CO. Test conditions are 23 5C and 50 10% RH. Indicative values only. Sampling test. IMPORTANT PRECAUTIONS: Read the following instructions carefully before using the MiCS-5524 described here to avoid erroneous readings and to prevent the device from permanent damage. * The sensor must be reflow soldered in a neutral atmosphere, without soldering flux vapours. * The sensor must not be exposed to high concentrations of organic solvents, silicone vapours or cigarette-smoke in order to avoid poisoning the sensitive layer. * Heater voltage above the specified maximum rating will destroy the sensor due to overheating. * This sensor is to be placed in a filtered package that protects it against water and dust projections. * SGX sensortech strongly recommends using ESD protection equipment to handle the sensor.

The resulting voltage is typically VH = 2.4V. The voltage measured on the load resistor is directly linked to the resistance of the sensor respectively. RLOAD must be 820 at the lowest in order not to damage the sensitive layer. Power circuit and measurement circuit R is a 82 .

The sensors are placed in a carrier type. The dimensions of the cavity are 5.5 x 7.5 x 2.55 mm (the tolerance is +/- 0.2 mm). The outside dimension of the reel is either 178 +- mm (for a maximum of 700 sensors ) or 330 + 0.25 / -4 mm (for a maximum of 2000 sensors).
