FEATURES
APPLICATIONS
• With a lead pitch of 2.5mm (identical to the terminal pitch of DIP
type ICs), the ZJSC series T-type EMC filters enable the design
of high-density circuit board configurations using automated
insertion.
Home electronic equipment, (TVs, VCRs, CD players, DAT play-
ers, electric musical instruments, PCs, etc.), office automation
equipment (computers, terminals, stand-alone word processors,
fax machines, etc.), factory automation equipmen
• Their sharp cutoff characteristics provide effective high-
frequency attenuation with minimum effect on passband signals,
even when such signals are at close proximity to the trapband.
• The series are available in an extensive range of cutoff
frequencies, enabling their use in a wide range of applications.
• The use of highly miniaturized inductor elements helps minimize
variations in the mounted heights of circuit board components.
This plus the use of round leads ensures superior clinchability
and insertability, making this product ideal for use in automated
mounting production lines.
