Storage conditions & shelf life It can be stored for 2 years under closed conditions with temperature of 5 ° C ~ 35 ° C and relative humidity of 40 ~ 75 Please avoid the following harsh environment during storage to avoid affecting the product performance and solder connectivity: the places with corrosive gases such as sea breeze, Cl2, H2S, NH3, SO2 and NO2 shall be stored without direct sunlight. Precautions for product use When measuring the resistance value before welding, a special resistance meter with high precision shall be used. When measuring, a 4-wire probe or fixture must be used. 4. When measuring parts with a wire measuring needle, the 4 measuring needles must indeed contact the parts. Avoid damaging the protective layer during manual welding or clamping with tweezers. When the PCB is divided or fixed on the support, be careful to avoid excessive bending causing mechanical stress to the resistor. It shall be used within the rated power range within the specification, especially when the power exceeds the rated value, which may affect the reliability of the product Specifications are subject to change without notice.
