Z-SMS 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
“A” Suppresses the XL component. Helps stop the reduction of the wave-form
“B” Increases the Z characteristics sharply above 20MHz and is applicable for
“C” Designed as a noise countermeasure for 200MHz-500MHz range where the
“D” Intended for noise suppression around 200MHz. Effectively increase
“E” The best material in the Z-SMS Series to suppress the XL component and stop
“F” Reduced DC resistance version for noise countermeasures around LSI power
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
• 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”
Z-PMS Applications:
• High frequency noise countermeasures on the DC power supply line in
• 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)
and other information system products. For use on digital product clock lines
and general signal lines.
material is extremely effective as a noise filter on LSI power supplies where
downsizing of components is needed.
