BLU99
BLU99 is UHF power transistor manufactured by NXP Semiconductors.
- Part of the BLU comparator family.
DESCRIPTION N-P-N silicon planar epitaxial transistor primarily intended for use in mobile radio transmitters in the u.h.f. band. The transistor is also very suitable for application in the 900 MHz mobile radio band. FEATURES - multi-base structure and diffused emitter-ballasting resistors for an optimum temperature profile; - gold metallization ensures excellent reliability. The BLU99 has a 4-lead stud envelope with a ceramic cap (SOT122A). All leads are isolated from the stud. The BLU99/SL is a studless version (SOT122D).
