Description

INTRODUCTION

This standard, which shows quartz crystal unit holder outlines
and pin connections, includes the outlines previously shown in
RETMA Standard RS-192, July 1957; those of interest to the U. S.
published in International Electrotechnical Commission (I.E.C.)
publication 122-3; those being considered by I.E.C. committee
TC-49; and the latest outlines now in commercial use reviewed by
EIA committee TR-26. These outlines have been regrouped, and
different number assignments have been made from those given in
RS-192 in order to place all plastic, vacuum tube type, and metal
type holders in a more logical sequence.

A cross reference is given to show the similarities between the
numbered holders in this standard and the military types.

The dimensional letters and arrangements are essentially in
conformance with the recommended practice for preparation of
outline drawings of electron tubes as set forth in EIA Standard
RS-202-A, January 1964. Millimeter-inch conversions and tolerances
have been assigned in accordance with I.E.C. 39 (CO) 135 dated a
Nov 63.

The list of pin connections for crystal vibrators in the various
holder types are the same as those accepted by I.E.C. committee
TC-49 as set forth in I.E.C. 49 (CO) 9 dated Feb 64.
