Introduction

Miniaturization is the development direction of components. The development of resistance-capacitance components in the past 10 years, the most prominent performance is the rise of surface mount components.

Surface mount preset potentiometer is one of the representative products. The production of this kind of product has been developed in our country in recent years.

There are not too many manufacturers and varieties, but considering that this type of product is the development direction of future products, it is necessary to standardize its development and production, so This requires the development of this document. "Potentiometers for Electronic Equipment" is divided into general specifications, sub-specifications and blank detailed specifications. It is proposed to be composed of the following 13 parts.

--- Part 1. General Specifications. The purpose is to establish the terminology, quality assessment procedures, test methods and measurement procedures of potentiometers.

--- Part 2. Sub-specification. screw drive and rotary preset potentiometer. The purpose is to establish the optimum Priority values, characteristics and general performance requirements, and select applicable quality assessment procedures, test and measurement methods from the general specification.

--- Part 2. Blank detail specification. screw drive and rotary preset potentiometer evaluation level E. The purpose is to establish the level of assessment Requirements for the format, arrangement and essential content of the detail specification for screw-driven and rotary preset potentiometers of E.

--- Part 3. Sub-specification. Rotary precision potentiometer. The purpose is to establish the preferred ratings, characteristics and general characteristics of rotary precision potentiometers General performance requirements, and select applicable quality assessment procedures, tests and measurement methods from the general specification.

--- Part 3. Blank detail specification. rotary precision potentiometer assessment level E. The purpose is to establish the rotation of the assessment level E Requirements for the format, layout and basic content of detailed specifications for type precision potentiometers.

--- Part 4. Sub-specification. single-turn rotary power potentiometer. The purpose is to establish the priority value of the single-turn rotary power potentiometer, Characteristics and general performance requirements, and select applicable quality assessment procedures, test and measurement methods from the general specification.

--- Part 4. Blank detail specification. single-turn rotary power potentiometer rating level E. The purpose is to establish the assessment level as E Requirements for the format, arrangement and basic content of the detailed specification for single-turn rotary power potentiometers.

--- Part 4. Blank detail specification. single-turn rotary power potentiometer rating level F. The purpose is to establish an assessment level of F Requirements for the format, arrangement and basic content of the detailed specification for single-turn rotary power potentiometers.

--- Part 5. Sub-specification. Single-turn rotary low-power potentiometer. The purpose is to establish the priority of single-turn rotary low power potentiometer Values, characteristics and general performance requirements, and select applicable quality assessment procedures, test and measurement methods from the general specification.

--- Part 5. Blank detail specification. Single-turn rotary low-power potentiometer rating level E. The purpose is to establish the assessment level as Requirements for the format, arrangement and basic content of the detail specification for single-turn rotary low-power potentiometers of E.

--- Part 5. Blank detail specification. Single-turn rotary low-power potentiometer rating level F. The purpose is to establish the assessment level as Requirements for the format, arrangement and basic content of the detail specification for single-turn rotary low-power potentiometers of F.

--- Part 6. Sub-standard surface mount preset potentiometers. The purpose is to establish the preferred values, special and general performance requirements, and select applicable quality assessment procedures, test and measurement methods from the general specification.

--- Part 6-1. Blank Detail Specification Surface Mount Preset Potentiometer Evaluation Level EZ. The purpose is to establish the assessment level as Requirements for the format, layout and basic content of the detail specification for surface mount preset potentiometers of EZ.

This document is a blank detailed specification, which is a supplement to the general specification and sub-specifications. This document is published in IEC 60393-1:2008 "Electronic equipment Spare potentiometers - Part 1.
