NEW PRODUCT
LOW PASS FILTER TECHNOLOGY
LC and RC filters are offered by BI to solve issues of
unwanted noise. Each has cost/performance trade offs.
LC composite construction has superior performance
through the entire frequency range and has the sharpest
roll off compared with RCs.
APPLICATIONS
Thick film RC is the lowest cost and provides good
performance.
Thin film RC offers good performance (under 1GHz),
moderate cost and very good multi-element density.

FILTER DESIGN COMPARISON AND BENEFITS
Low pass filters are most commonly used in high
frequency circuits where the probability of noise is
significant.
The LC Series, a ladder type low pass filter, is the
most suitable for attenuating unwanted noise.
The LC Series is an integrated passive device with the
equivalent of four inductors and three capacitors
imbedded into a single 0805 or 1206 monolithic chip.
The LC Series
integrated passive ladder construction
ENVIRONMENTAL
is superior to discrete solutions at
high frequencies
due to very short internal interconnections.
The LC Series' ladder construction is superior to "T"
styles by offering greater attenuation beyond the cutoff
frequency.
The LC Series low pass filters offer
steeper
insertion
loss and
greater
noise attenuation than other filters.
The LC Series provides signal attenuation below -20dB
above 1GHz.
