FEATURE

1. Unbalanced π type attenuator circuit in one chip (1.0mm x 1.0mm)

2. Mounting occupation area reduction

3. Mounting assembly cost saving

APPLICATION

•

Attenuation, level control, impedance matching of high frequency signals of communication equipment;

Mobile phone (GSM, CDMA, PDC, etc,…)

Telecom

DESCRIPTION

The attenuator is constructed in a high grade ceramic body (aluminum oxide). 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 rectangular marker indicates input pin1 as shown in circuit configuration.

SOLDERING CONDITION

The robust construction of chip resistors

allows them to be completely immersed in a

solder bath of 260°C for 10 seconds.

Therefore, it is possible to mount Surface

Mount Resistors on one side of a PCB and

other discrete components on the reverse

(mixed PCBs).

Surface Mount Resistors are tested for

solderability at 235°C during 2 seconds. The

test condition for no leaching is 260°C for 30

seconds. Typical examples of soldering

processes that provide reliable joints without

any damage are given in Fig 3.
