＊Except
for BK0402, BK0603, BK1005, BKH1005
■
FEATURES
◦
Internal silver printed layer creates a closed circuit which acts as a
magnetic shield minimizing heat generation and crosstalk.
◦
No need for grounding provides greater circuit design flexibility.
◦
Several material types and a broad range of impedance values pro-
vide noise countermeasures for various applications.
HS
：
With low R-XL cross point frequency characteristics and large
resistance part working as damping function, suppresses un-
necessary resonance and keeps signal integrity.
HW
：
With a lower R-XL cross point frequency characteristics than
those of HS, strongly suppresses unnecessary resonance.
TS
：
Low DC resistance HS version. For power supply lines .
HM
：
Resistance part rising exceeding from 20MHz. For general us-
age, especially effective for video signal lines.
HR
：
Resistance part rising exceeding from 10MHz. For general us-
age, Wider effective range than that of HM.
LM
：
With larger impedance set at around 200MHz considering for
noise regulation.
LL
：
Resistance part steeply rising exceeding from 100MHz. For high
speed signal line, good for clock line, sharply cutting noise off.
◦
The small case size lineup with 01005 inch size.
■
APPLICATIONS
◦
igh frequency noise countermeasure in personal computers, digital
H
cameras and other information system products. For use on digital
product clock lines and general signal lines.
◦Radiated
noise suppression in computer or printer interfaces and har-
ness connectors.
◦Noise
suppression in video and other AV products.
◦
revents interference between circuits in cellular phones PHS, PDC,
P
（
etc.）
◦Due
to the closed internal circuit which acts as a magnetic shield, the
TS material is extremely effective as a noise filter on LSI power supply
lines where downsizing of components is needed.
