BK Features:
Internal silver printed layer creates a closed circuit which acts as a magnetic
shield to minimize heat generation and crosstalk
No need for grounding provides greater circuit design flexibility
Several material types and a broad range of impedance values provide noise
countermeasures for various applications
HS: Suppresses the XL component. Helps stop the reduction of the wave-form
integrity (digital wave-form overshoot, etc)
HM: Increases the Z characteristics sharply above 20MHz and is applicable for
radiated noise in the 100MHz-300MHz range. Especially effective on video
signal lines.
LL: Designed as a noise countermeasure for 200MHz-500MHz range where the
rise of the Z component is in the high frequency area.
LM: Intended for noise suppression around 200MHz. Effectively increase
attenuation
HW: The best material in the BK Series to suppress the XL component and stop the
reduction of the wave-form integrity while maintaining attenuation in the high
frequency area.
TS: Reduced DC resistance version for noise countermeasures around LSI power
supplies
BKP Features:
Low Rdc values reduce power dissipation and extend battery life
No need for grounding provides greater circuit design flexibility

BK Applications:
High frequency noise countermeasure in personal computers, digital 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 harness connectors.
Noise suppression in video and other AV products
Prevents interference between circuits in cellular phones (PHS, PDC, 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 supplies where downsizing
of components is needed.
BKP Applications:
High frequency noise countermeasures on the DC power supply line in personal
computers and other information system products
Noise suppression in USB and IEEE1294 interface
Prevents interference between circuits in mobile systems (PDC, PHS, PDA)
Operating Temperature:
BK:
-55oC to +125oC (includes self-generated heat)
BKP: -55oC to +85oC (includes sel-generated heat)
