BK Features:
• Internal silver printed layer creates a closed circuit which acts as a magnetic
• No need for grounding provides greater circuit design flexibility
• Several material types and a broad range of impedance values provide noise
HS: Suppresses the XL component. Helps stop the reduction of the wave-form
HM: Increases the Z characteristics sharply above 20MHz and is applicable for
LL: Designed as a noise countermeasure for 200MHz-500MHz range where the
LM: Intended for noise suppression around 200MHz. Effectively increase
HW: The best material in the BK Series to suppress the XL component and stop the
TS: Reduced DC resistance version for noise countermeasures around LSI power
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
• 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
BKP Applications:
• High frequency noise countermeasures on the DC power supply line in personal
• Noise suppression in USB and IEEE1294 interface
• Prevents interference between circuits in mobile systems (PDC, PHS, PDA)
Operating Temperature:
