FOR AM APPLICATIONS 450–470kHz
SFU/SFZ SERIES
FEATURES
s Center frequency range between 450
and 470kHz is available. Standard
tolerance is ±2kHz.
s For synthesizers, the types of center
frequencies 450, 459 and 468kHz
are available. Standard tolerance
is ±1kHz.
s The part numbers of the types for
synthesizers are as follows:
(In case of 450kHz)
SFU450A3 (for contact to resistor)
SFU450C5 (for contact to resistor)
SFU450B14 (for contact to IFT)
SFZ450HL3/JL3/KL3
SFZ450H3/J3/K3 (for contact
to resistor)
