Cautions and warnings ■ Please note the recommendations in our Inductors data book (latest edition) and in the data sheets. – Particular attention should be paid to the derating curves given there. – The soldering conditions should also be observed. Temperatures quoted in relation to wave soldering refer to the pin, not the housing.
