■ FEATURES
■ APPLICATIONS
◦Internal silver printed layer creates a closed circuit which acts as a
◦Hꢀ igh frequency noise countermeasure in personal computers, digital
cameras and other information system products. For use on digital
product clock lines and general signal lines.
magnetic shield minimizing heat generation and crosstalk.
◦No need for grounding provides greater circuit design flexibility.
◦Radiated noise suppression in computer or printer interfaces and har-
ness connectors.
◦Several material types and a broad range of impedance values pro-
vide noise countermeasures for various applications.
◦Noise suppression in video and other AV products.
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.
◦Pꢀ revents interference between circuits in cellular phone（s PHS, PDC,
etc.）
HW：With a lower R-XL cross point frequency characteristics than
◦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.
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.
■ OPERATING TEMP.
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.
