ZJSR Series
3-Terminal Filters for Signal Line and DC Power Line
Lead(Round)
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.

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.)
BASIC CHARACTERISTICS
This product should not be used under conditions that exceed those
listed above.
Please note that this product is an EMC filter, so should not be used as a
surge absorber, etc.
Dimensions in mm
The tolerance of lead pitch is the dimensions when a lead is released
from tape. Not available for bulk packaging.
