FEATURES
• Laser Trimmed
• Temperature Stable
GENERAL INFORMATION
The PCA and PCAA Series consists of a laser trimmed distrib-
uted thin film element on an alumina ceramic substrate with
solderable terminals. Two sizes are available. The PCA size
operates to 12.4 GHz and the PCAA size operates to 18.0 GHz.
Both sizes are available with leads and wrap around conduc-
tors for ease of installation. The PCAF and PCAAF options are
designed for “flip-chip” application in lower frequency circuits.
PCA & PCAA SERIES DATA
• Substrate: 96% Alumina
• Solderable Terminals: Electroplated Silver over Nickel
• Resistive Element: Proprietary Thin Film
• Wrap around Ground Terminal available, “W” option
• Wrap around-all terminals—“F” option
• Standard values 1, 2, 3, 4, 5, 6, 10, 20 dB
• Non-std. values available as special order

ORDERING INFORMATION
The attenuators listed are available in 1 dB increments from 1
through 20 dB. When ordering, to specify the correct part num-
ber for the desired attenuation value, select any of the series
listed and add the attenuation value desired to the basic series
designation.
