BB187 VHF variable capacitance diode Rev. 5 6 September 2011 Product data sheet 1. Product profile 1.1 General description The BB187 is a planar technology variable capacitance diode, in a SOD523 (SC-79) ultra small plastic SMD package. The excellent matching performance is achieved by gliding matching and a Direct Matching Assembly (DMA) procedure. 1.2 Features and benefits High linearity Excellent matching to 2 % DMA Ultra small plastic SMD package C : 2.75 pF C to C ratio: minimum 11 d(25V) d(2V) d(25V) Low series resistance. 1.3 Applications Electronic tuning in VHF television tuners Voltage Controlled Oscillators (VCO). 2.
