BLU45-12 Datasheet | Philips Semiconductors

DESCRIPTION N-P-N silicon planar epitaxial transistor in SOT-119 envelope primarily intended for use in mobile radio transmitters in the 470 MHz munications band. FEATURES - multi-base structure and emitter-ballasting resistors for an optimum temperature profile. - internal matching to achieve an optimum wideband capability and high power gain. - gold metallization ensures excellent reliability. BLU45/12 The transistor has a 6-lead flange envelope with a ceramic cap. All leads are isolated from the flange.
