Description
770 Series Chip Arrays are single packaged devices containing an array of homogeneous resistor elements. Arrays
are typically used for convenience when several resistors occupy the same area in a layout. Multiple package
sizes and circuit configurations help save placement costs by reducing application component count.

Power Derating Curve – Typical
With the rated ambient temperature set to +25°C, the maximum power [maximum current for 0Ω product] at a temperature of no more
than rated ambient temperature shall be equal to the rated power [rate current for 0Ω product]. The maximum power at a temperature
exceeding the rated ambient temperature shall be a value determined by reducing the rated power according to the power reduction
curve in the figure below.

Rated Voltage
The rated voltage shall be the DC or AC [effective power frequency] voltage corresponding to the rated power and shall be determined
with the formula shown below. If the determined rated voltage exceeds the maximum operating voltage specified in Operating Conditions
table, the maximum operating voltage shall be the rated voltage.
E = Rated Voaltge [V]
E = √ PxR
P = Rated Power [W]
R = Nomimal Resistance [Ω]
