BB178
Datasheet
General description
The BB178 is a planar technology variable capacitance diode, in a SOD523 (SC-79) ultra small plastic package. The excellent matching performance is achieved by gliding matching and a Direct Matching Assembly (DMA) procedure.
Features
- Excellent linearity
- Excellent matching to 2 pct DMA
- Ultra small plastic SMD package
- Cd(28V): 2.6 pF; Cd(1V) to Cd(28V)ratio: 15
- Very low series resistance.
