AEC-Q200
Qualified
Type 3521 Series
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
=
√P x R
Where:
RCWV = Rated DC or RMS AC continuous working voltage at
commercial-line frequency and waveform (volt)
P = Power Rating (watt)
R = Nominal Resistance (ohm)
In no case shall the rated DC or RMS AC continuous working voltage be greater
than the applicable maximum value.

Storage Condition
The performance of these products, including the solderability, is guaranteed
for a year from the date of arrival at your company, provided that they
remain packed as they were when delivered and stored at a temperature of
25°C ± 10°C and a relative humidity of 60%RH ± 10%RH, chemical and dust
free atmosphere
Even within the above guarantee periods, do not store these products in the
following conditions, otherwise their electrical performance and/or
solderability may be deteriorated, and the packaging materials (e.g. taping
materials) may be deformed or deteriorated, resulting in mounting failures.
1. In salty air or in air with a high concentration of corrosive gas, such as Cl2,
H2S, NH3, SO2, or NO2
2. In direct sunlight
