TV Tuning
• High capacitance ratio: C2 V/C25 V = 6.5 (typ.)
• Low series resistance: rs = 0.4 Ω (typ.)
• Excellent C-V characteristics, and small tracking error.
• Useful for small size tuner.
Absolute Maximum Ratings (Ta = 25°C)
Characteristics Symbol Rating Unit
Reverse voltage VR 30 V
Peak reverse voltage VRM 35 (RL = 10 kΩ) V
Junction temperature Tj 125 °C
Storage temperature range Tstg −55~125 °C
Note: Using continuously under heavy loads (e.g. the application of high
temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the
reliability significantly even if the operating conditions (i.e.
operating temperature/current/voltage, etc.) are within the
absolute maximum ratings.
Please design the appropriate reliability upon reviewing the
Toshiba Semiconductor Reliability Handbook (“Handling
Precautions”/“Derating Concept and Methods”) and individual
reliability data (i.e. reliability test report and estimated failure rate, etc).
