Reliability data Caution When bending the lead wires using for example a radio Item Test conditions Criteria plier make sure to have a minimum distance from the Resistance to soldering 10 s at 260 or R, B 0.5% and heat 3.5 s at 340 visual inspection sensor head of 3 mm. 2 s at 245 Solderability More than 90% soldered Do not apply a mechanical load of more than 2 N in the Flux material: Rosin 25%, ethyl alcohol 75% way depicted in Fig. 1 below. Tensile strength A load of 2 N is applied to the wire terminations in (lead wire) vertical direction for 10 s. (See Fig. 1) The lead wire is bent to an angle of 90 and then R, B 0.5% and Termination bending back into the original position. visual inspection Three times natural fall to a maple board from 1 m Free fall height. 2N Fig. 1 Voltage proof 1000 V AC for one minute Less than 1 mA Insulation resistance 500 V DC Over 100 M When soldering make sure to have a minimum Dry heat 1000 hours at 150 distance of 5 mm, use a soldering iron with 50 W Damp heat 1000 hours at 40 and 90% humidity and solder for maximum seven seconds at 340C.
