FEATURES
APPLICATIONS
• Smallest-in-the-industry-class compact, thin, and lightweight
chip low pass filter manufactured in ceramic sheet multilayering
process (L1.6×W0.8×T0.8mm/4mg).
Cellular and digital cordless phones.
TEMPERATURE RANGES
• Wide range of characteristics including low loss type
(corresponding to 3rd level) to high attenuation type
(corresponding to 5th level) achieved according to circuit in use.
• Provided with excellent environmental resistance and stable
characteristics achieved under use of portable remote terminal
in hostile environment.
