Z-SMS 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 (10th digit in part number)
“A” Suppresses the XL component. Helps stop the reduction of the wave-form
integrity (digital wave-form overshoot, etc)
“B” Increases the Z characteristics sharply above 20MHz and is applicable for
radiated noise in the 100MHz-300MHz range. Especially effective on video
signal lines.
“C” Designed as a noise countermeasure for 200MHz-500MHz range where the
rise of the Z component is in the high frequency area.
“D” Intended for noise suppression around 200MHz. Effectively increase
attenuation
“E” The best material in the Z-SMS Series to suppress the XL component and stop
the reduction of the wave-form integrity while maintaining attenuation in the
high frequency area.
“F” Reduced DC resistance version for noise countermeasures around LSI power
supplies
Z-PMS Features:
• Low Rdc values reduce power dissipation and extend battery life
• No need for grounding provides greater circuit design flexibility

Z-SMS 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 “F”
material is extremely effective as a noise filter on LSI power supplies where
downsizing of components is needed.
Z-PMS 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:
• Z-SMS: -55ºC to +125ºC (includes self-generated heat)
• Z-PMS: -55ºC to +85ºC (includes self-generated heat)
