TISP1072F3 Bourns, Inc., TISP1072F3 Datasheet - Page 13

• Manufacturer Part Number: TISP1072F3
• Description: Overvoltage Protector Series
• Manufacturer: Bourns, Inc.

Figure 22 shows a three terminal TISP
terminal pair capacitance measured with a three terminal or guarded capacitance bridge. If wire R is biased at a larger potential than
wire T, then C
line capacitive unbalance is due to (C
All capacitance measurements in this data sheet are three terminal guarded to allow the designer to accurately assess capacitive
unbalance effects. Simple two terminal capacitance meters (unguarded third terminal) give false readings as the shunt capacitance via
the third terminal is included.
