PRODUCT DATA Micro International, Inc PART NUMBER LDTBFW30 and LDTBFW30T Micro-LID NPN Transistor Micro International, Inc. 179-204 Belle Forrest Circle Nashville, TN 37221 Tel: 615-662-1200 Fax 615-662-1226 www.microlid.com [email protected] Micro-LID Transistors LDTBFW30 and LDTBFW30T Description: The LDTBFW30 (untinned) and LDTBFW30T (tinned) are NPN silicon 1.6 GHz wideband transistors in very small, rugged, surface mount, 4-post ceramic packages (Micro International manufactured package p/n 4-075-1). The LDTBFW30 and LDTBFW30T meet the general specifications of the BFW30 transistor. The 4-075-1 Micro-LID package is a 4-post, leadless ceramic carrier which can be provided with gold metallized or pre-tinned lands, and is approved for military, medical implant, sensor, and high reliability applications. The LDTBFW30 and LDTBFW30T can be provided with special feature options such as additional temperature cycling, screening, and matching Hfe selection.
