ORDERING EXAMPLE
The ordering code of an ATV321 attenuator with
2±0.3 dB attenuation, supplied in 7-inch tape reel is:
ATV321CR-072dBL.
(6) RESISTOR TERMINATIONS
L = Lead free terminations (pure Tin)
NOTE
1. The “L” at the end of the code is only for ordering. On the reel
label, the standard CTC will be mentioned an additional stamp
“LFP”= lead free production.
2. Products with lead in terminations fulfil the same requirements
as mentioned in this datasheet.
3. Products with lead in terminations will be phased out in the
coming months (before July 1st, 2006)

MARKING
No marking.
CONSTRUCTION
The attenuators are constructed on a high-grade
ceramic body (aluminium oxide). The internal
circuit is applied to the top surface of the substrate,
and its design determines the required attenuation
value. The attenuation layer is covered with a
protective coating and a marking dot indicates input
pin 1 as shown in the connection diagram of Fig.1.
The rectangular marker designates input pin 1.

Finally, the four external end terminations are
added. To guarantee optimum solderability the
outer layer of the terminations are lead free (pure
Tin).

FUNCTIONAL DESCRIPTION
POWER RATING
ATV321rated power at 70°C is 40 mW
RATED VOLTAGES
The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V=√(P X R)
Where
V=Continuous rated DC or
AC (rms) working voltage (V)
P=Rated power (W)
