BB134 数据手册
LESHAN RADIO COMPANY, LTD. UHF Variable Capacitance Diode FEATURES · Excellent linearity · Excellent matching to 0.5% DMA · Very small plastic SMD package · C28: 1.9 pF; ratio: 10. · Low series resistance. APPLICATIONS · Electronic tuning in UHF television tuners. · VCO. DESCRIPTION The BB134 is a variable capacitance diode fabricated in planar technology, and encapsulated in the SOD323 very small plastic SMD package. The excellent matching performance is achieved by a direct matching assembly procedure. The unmatched type, BB135 has the same specification. 1 BB134 2 SOD– 323 MARKING DIAGRAM P4 1 CATHODE 2 ANODE LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).
