BB187
BB187 is VHF variable capacitance diode manufactured by Philips Semiconductors.
FEATURES
- High linearity
- Excellent matching to 2% DMA
- Ultra small plastic SMD package
- C25: 2.75 p F; ratio: 12
- Low series resistance. APPLICATIONS
- Electronic tuning in VHF television tuners
- Voltage controlled oscillators (VCO). DESCRIPTION
The BB187 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. PINNING PIN 1 2 DESCRIPTION cathode anode
