APPLICATIONS
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 equipment (robots, numeri-
cal control devices, process controllers, etc.), automotive electron-
ics (automotive engine control units, etc.)

FEATURES
• The ZJSR series combine TDK’s high performance ferrite bead
and a chip capacitor. This board mounted EMC filter is used to
prevent microcomputer operational errors and stop noise
generation. Most suitable for use in countering radio noise
generated by digital circuits.
• SIP shape with 2.4mm max. thickness, making possible high
density mounting upon a PCB in a row at DIP pitch.
• When using taped product, possible to mount using automatic
equipment.
• Excellent high frequency bypass performance due to short
earth-side capacitor lead.
