NOTE When products approved to the detail specification have different ranges, the following statement should be added: “The range of values available in each style is given in the qualified products list”. 1.4.5 Marking

32、 The detail specification shall specify the content of the marking on the surface mount resistor network and on the package. Surface mount resistor networks are generally not marked on the body. If some marking can be applied, the surface mount resistor network shall be clearly marked with the rated

33、 resistance and as many of the remaining items in 2.4 of IEC 60115-1 as possible. All items shall be marked on the package. Deviations from the above mentioned requirements shall be specifically stated. 2 Preferred ratings, characteristics and test severities 2.1 Preferred ratings and characteristic

34、s The values given in detail specifications shall preferably be selected from the following: 2.1.1 Preferred climatic categories The surface mount resistor networks covered by this specification are classified into climatic categories according to the general rules given in IEC 60068-1. The lower an

35、d upper category temperature and the duration of the damp heat, steady state shall be chosen from the following: Lower category temperature: 55 C, 40 C, 25 C and 10 C. Upper category temperature: +85 C, +100 C, +125 C and +155 C. Duration of the damp heat, steady state test: 4, 10, 21 and 56 days. T

36、he severities for the cold and dry heat tests are the lower and upper category temperatures respectively. Because of the construction of some surface mount resistor networks these temperatures will occur between two of the preferred temperatures given in IEC 60068-2-1 and IEC 60068-2-2. In this even

37、t, the nearest preferred temperature within the actual temperature range of the surface mount resistor network shall be chosen for this severity. 2.1.2 Temperature coefficients and temperature characteristics of resistance The preferred limits of change in resistance for the temperature characterist

38、ics of resistance test are given in Table 2. Page5 EN601159:2004Each line in the table gives the preferred temperature coefficient and corresponding temperature characteristic for 20 C to 70 C and limits of change in resistance for the measurement of the temperature characteristic of resistance (see

39、 4.8 of IEC 60115-1) on the basis of category temperature ranges of 2.1.1 of this sectional specification.
