BB182B 数据手册
LESHAN RADIO COMPANY, LTD. VHF variable capacitance diode FEATURES · High linearity · Excellent matching to 2% DMA · Ultra small plastic SMD package · C25: 2.8 pF; ratio: 17 · Low series resistance. APPLICATIONS · Electronic tuning in VHF television tuners, band A up to 160 MHz · Voltage controlled oscillators (VCO). DESCRIPTION The BB182B is a planar technology variable capacitance diode, in a SOD523 (SC-79) package. The excellent matching performance is achieved by gliding matching and a direct matching assembly procedure. 1 CATHODE 2 ANODE BB 182B 1 2 SOD523 SC-79 MARKING CODE:Y Y MAX. 34 35 20 +150 +125 UNIT V V mA °C °C MAX. – – – – – – – TYP. 10 200 1.1 53 3 – 2 % nA Ω pF pF 1 2 LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).
