1、JEDEC STANDARD The Measurement of Small-Signal VHF-UHF Transistor Short-Circuit Forward Current Transfer Ratio JESD371 (Previously known as RS-371 and/or EIA-371) FEBRUARY 1970 (Reaffirmed: April 1981, April 1999, March 2009) JEDEC SOLID STATE TECHNOLOGY ASSOCIATION NOTICE JEDEC standards and public
2、ations contain material that has been prepared, reviewed, and approved through the JEDEC Board of Directors level and subsequently reviewed and approved by the JEDEC legal counsel. JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings betwee
3、n manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or international
4、ly. JEDEC standards and publications are adopted without regard to whether or not their adoption may involve patents or articles, materials, or processes. By such action JEDEC does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the JEDEC
5、standards or publications. The information included in JEDEC standards and publications represents a sound approach to product specification and application, principally from the solid state device manufacturer viewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard or
6、 publication may be further processed and ultimately become an ANSI standard. No claims to be in conformance with this standard may be made unless all requirements stated in the standard are met.
