According to the classification number for the combination of capacitance deviations (hereafter ∆C), assembly method and automatic mounting equipment section, the following product names are assigned. Base model 1T363A Derived model 1T363A 04 M 20 A T8 A T8 A Note 1 : Package specification as ordered by customer ∗ Taping direction ∗ T8 only to consolidate specifications Special selection symbol Note 2 : ∆C kit number Note 3 : Assembly method M=MAP Note1) In taping packaging of products groups according to the ∆C classification, products must be divided according to the group. If taping is performed without grouping into categories, products from two different groups may be mounted on the same tuner, so that ∆C cannot be assured during tuning, making tuning defective. A: Panasert method; Sections are divided by four blank spaces on the carrier tape. B: Sanyo method; Black tape is affixed to one blank space on the carrier tape to mark sections. Note 2) ∆C kit number When taping each group, taping is performed in kit number multiples. 01; Incomplete kit (∆C not guaranteed) 04; 4 kits 20; 20 kits Recommended kit number; 4 and 20 Other) Minimum number of kits per group is 240 (60 or more at the beginning of the carrier tape). Up to nine sections on one reel. Note 3) “MAP” is the method where the neighboring chips are assembled continuously in order to enhance the concentration of the capacitance deviation in a matching group. —2— 1T363A Diode capacitance vs. Reverse voltage 100 Diode capacitance (pF) Ta=25°C f=1MHz 10 1 1 10 50 Reverse voltage (V) Reverse voltage vs. Ambient temperature VR-Reverse voltage (V) 1R=10µA 50 40 30 –20 0 20 40 60 Ta-Ambient temperature (°C) —3— 80 1T363A Diode capacitance vs. Ambient temperature Reverse current vs. Ambient temperature f=1MHz 1000 VR=1V 1.02 VR=28V 1.01 IR-Reverse current (pA) VR=2V VR=10V VR=25V 1.00 100 10 1 0.99 0.98 –20 0 20 40 60 80 –20 100 Thermal coefficient of diode capacitance 20 40 60 80 Reverse current vs. Reverse voltage 1000 100 Ta=60°C IR-Reverse current (pA) f=1MHz 100 10 0 Ta-Ambient temperature (°C) Ta-Ambient temperature (°C) Thermal coefficient (ppm/°C) C (Ta) diode capacitance C (25°C) 1.03 1 10 Ta=25°C 10 1 30 VR-Reverse voltage (V) 1 10 VR-Reverse voltage (V) —4— 100 1T363A Package Outline AAA AAA Unit : mm M-235 + 0.2 ∗1.25 – 0.1 ∗0.9 ± 0.1 + 0.1 0.3 – 0.05 0.2 2.5 ± 0.2 ∗1.7 ± 0.1 2 1 + 0.1 0.3 – 0.05 0 ± 0.05 + 0.1 0.11 – 0.06 0° to 10° NOTE: Dimension “∗” does not include mold protrusion.
