This part is part 6 of the series of national standards for "potentiometers for electronic equipment".

This section was drafted in accordance with the rules given in GB/T 1.1-2009.

The translation method used in this part is equivalent to the use of IEC 60393-6.2015 "Potentiometers for Electronic Equipment Part 6.Sectional Specification Surface Mount

Pre-adjusted potentiometer.

The Chinese documents that have a consistent correspondence with the normatively cited international documents in this section are as follows.

---GB/T 2691-2016 marking code for resistors and capacitors (IEC 60062.2004, IDT);

---GB/T 28162.3-2011 Packaging of components for automatic operation Part 3.Surface mount components on continuous tape

Packaging (IEC 60286-3.2007, IDT).

The following editorial changes have been made to this section.

a) Corrected the errors in the duration of group 3, group 6 and group 7 in Table 3 of IEC 60393-6.2015;

b) The performance requirements of rotating noise in Table 3 are changed from "Method B. <=ohm or% (whichever is greater)" to "Method B. <=ohm or %R (whichever is greater)

The bigger one)";

c) The amount of change in the resistance of the resistor in Table 3 is changed from "deltaR<=+/-(% ohm)" to "deltaR<=+/-(%R ohm)".

This part was proposed by the Ministry of Industry and Information Technology of the People's Republic of China.

This part is under the jurisdiction of the National Standardization Technical Committee for Resistance and Capacitance Components for Electronic Equipment (SAC/TC165).
