(see ordering information table). quality statement the products are designed and manufactured in an industrial environment wher e quality systems and methods like iso 9000, 6 (sigma), and spc are intensively in use to boost the continuous improvements strategy. infant mortality or early failures in the products are screened out and they are subjected to an ate-based final test. conservative design rules, design reviews and product qualifications, plus the high competence of an engaged work force, contribute to the high quality of our products. warranty warranty period and conditions are defined in ericsson power modules general terms and conditions of sale. limitation of liability ericsson power modules does not make any other warranties, expressed or imp lied including any warranty of merchantability or fitness for a particular purpose (including, but not limited to, use in life support applications, where malfunctions of product can cause injury to a person?s health or life). e pkr 4000b series dc/dc converters, input 36-75 v, output up to 5 a/15 w en/lzt 146 301 r6d september 2007 ? ericsson power modules ab technical speci? cation 2
