20、mature-type, circuit-board-mounted relays permitting board center spacings of less than 1 inch. These relays generally are classed in the load range of O to. 2 amperes. This document is intended to help define standard packages, footprints and test conditions so as to promote interchangeability. Rel

21、ays conforming to this standard are suitable for use in electrical and electronic equipment where application is within the stated limits of operation. Relays conforming to this standard may be tested as defined in applicable sections of EIA-407A, EIA/NARM Standard Testing Procedures for Relays for

22、Electrical and Electronic Equipment. This standard does not apply to either mercury-wetted or dry-reed relays. 2.
