Custom solutions are available.
AAC AT series high performance 0402, 0805,
1206, and 1612 size thin film fixed chip
attenuators exhibit excellent high frequency
characteristics. The surface mount package is
ideal for low noise, inductance and parasitic
capacitance applications. The thin film
metallization also offers very stable
characteristics over temperature and time.

Attenuation Value

Impedance
C = 50Ω
D = 75Ω (for 1612 size)
Gain adjustment and impedance matching
in high frequency circuits. Because control
circuits need signals with identical levels, and a
receiver receives signals with different signal
levels, signal levels could be adjusted by
combining a SMT attenuator and amplifier. At
the same time, termination can be obtained
using these low reflection attenuators.

ADHESION STRENGTH OF COVER AT PEELING
When the cover tape is peeled off in such a manner as indicated
in the illustration below, adhesion strength F must be within the
range of 0.2994 ± 0.196N.
The standard number of attenuators to be accommodated by
one reel is as indicated in Table 1. One side surface of a reel is
marked with the following items of information.

PACKING & STORAGE
The attenuators are packed in such a manner that they will not
possibly be damaged during transit or storage. As far as they
are stored at normal temperature with normal humidity (5 to
35°C, below75% RH), they are warranted for a period of two
years from the date of manufacture.
