Description
The 1T378A is a variable capacitance diode designed for electronic tuning of wide-band CATV tuners, and the super miniature package allows the tuner miniaturization.
High capacitance ratio (C25/C28) is improved to support guard band.

Features
• Super miniature package
• Low series resistance 0.85 Ω Max. (f=470 MHz)
• Large capacitance ratio 12.5 Typ. (C2/C25)
                                         1.03 Min. (C25/C28)
• Small leakage current 10 nA Max. (VR=28 V)
• Capacitance deviation within 2 %

Applications
   Electronic tuning of VHF band and wide-band
   CATV tuners
