This EIA Standard is a revision and update of EIA-198-0 covering ceramic dielectric
31、capacitors. Clarification Statement The purpose of this clarification statement is to advise the reader that it is EIA procedure when revising a standard to include all of the outstanding addendums of the standard being superseded in the revision. Accordingly, previously published addendums to EIA-1
32、98-8; EIA-198-8-1: EIA-198-8-2; EIA-198-8-3A and EIA-198-C1 EIA-198-D have been incorporated into EIA-198-E. EIA-198-2-E Page 2 THIS PAGE INTENTIONALLY LEFT BLANK EIA-198-2-E Page 3 1 Introduction 1.1 Scope This standard establishes uniform methods for testing ceramic capacitors, including basic env
33、ironmental tests to determine resistance to deleterious effects of natural elements, and physical and electrical tests. The tests described herein have been prepared to serve several purposes. a) To specify suitable conditions obtainable in the laboratory which give test results equivalent to the ac
34、tual service conditions existing in the field, and to obtain reproducibility of the results of tests. The test methods described herein are not to be interpreted as an exact and conclusive representation of actual service operation in any one geographic location, since it is known that the only true
35、 test for operation in a specific location is an actual service test at that point; b) To describe in one standard (1) all of the test methods applicable to ceramic capacitors described in EIA-198, (2) those newly-developed test methods that are feasible for use in several standards, and (3) the rec
36、ognized extreme environments, particularly temperatures, barometric pressures etc., at which capacitors will be tested under some of the presently-standardized testing procedures. By so consolidating, these methods may be kept uniform and thus result in conservation of equipment, man-hours, and test
37、ing facilities. In achieving these objectives, it is necessary to make each of the general tests adaptable to a broad range of ceramic capacitors; c) The test methods described herein for environmental, physical and electrical evaluation of electronic parts shall also apply, when suitable, to parts
38、not covered by an approved specification or drawing. 1.2 Numbering System The test methods are designated by numbers assigned in accordance with the following system: 1.2.1 Class of Test The tests are divided into three classes: Test methods 101 to 199 inclusive cover parametric conformance; those n
39、umbered 201 to 299 inclusive, cover environmental performance; and those numbered 301 to 399 inclusive cover physical conformance. Within each class, test methods are serially numbered in the order in which they are introduced into this standard. 1.2.2 Revision of Test Methods. The test method revis
40、ion is indicated by a letter following the method number. For example, the original number assigned to the Capacitance and Dissipation Factor test method is 101; the first revision is 101-A, the second revision is 101-B, etc. EIA-198-2-E Page 4 2 General Requirements 2.1 Test Requirements. The requi
41、rements which must be met by the component parts subjected to the test methods described herein are specified in the individual specifications, as applicable, and the tests shall be applied as specified therein. Whenever this standard conflicts with the individual specification, the latter shall gov
42、ern. 2.2 Test Conditions. Unless otherwise specified herein, or in the individual specification, all measurements and tests shall be made at ambient or “room“ conditions as defined below under general requirements. Whenever ambient conditions must be closely controlled in order to obtain reproducibl
43、e results for referee purposes, the stricter conditions listed below shall be specified. CONDITION Temperature Barometric Pressure Relative Humidity GENERAL REQUIREMENTS 25 C +/- 3C 650 to 800 mm of mercury not to exceed 75 percent CONTROL REQUIREMENTS 25 C +/-1 C 650 to 800 mm of mercury, 50 +/-2 p
44、ercent 2.2.1Sample Conditioning (Classes II, Ill, and IV only) Aging characteristics of ceramic dielectrics in Class II and higher can be significant and must be controlled when performing pre- and post-test electrical measurements. An acceptable protocol is: a. Deage at 150 C (or rated temperature,
45、 whichever is higher) for two hours minimum. b. Stabilize at room temperature for a minimum of 24 hours. c. Measure electrical parameters between 24 and 72 hours after last heat. 2.2.2 Permissible temperature variation in environmental chambers. When chambers are used, specimens under test shall be
46、located only within the working area defined as follows: a) Temperature variation within working area: The controls for the chambers shall be capable of maintaining the temperature of any single reference point within the working area within +/-2 C. b) Space variation within working areas: Chambers
47、shall be so constructed that, at any given time, the temperature of any point within the working area shall not deviate more than 3 C from the reference point, except in the immediate vicinity of specimens generating heat.
