AEC-Q200
Qualified
TE Connectivity is pleased to announce that our 3521 series high power Thick Film
Chip Resistor is now AEC-Q200 Qualified. This low cost device, suitable for auto
placement in volume, and for most applications, including high frequency
operations, owing to the short lead structure, is attractively priced and available on
7" reels of 4000 pieces.

Voltage Rating:
Resistors shall have a rated direct-current (DC) continuous working voltage or
an approximate sine-wave root-mean-square (RMS) alternating-current (AC)
continuous working voltage at commercial line frequency and waveform
corresponding to the power rating , as determined from the following formula:
RCWV
Where:
RCWV =
Rated DC or RMS AC continuous working voltage at
commercial-line frequency and waveform (volt)
