BB187LX
BB187LX is VHF variable capacitance diode manufactured by NXP Semiconductors.
description
The BB187LX is a planar technology variable capacitance diode in a SOD882T ultra small leadless plastic SMD package. The excellent matching performance is achieved by gliding matching and a Direct Matching Assembly (DMA) procedure.
