these ARE RF attenuators with 50¥Ø, 75¥Ø, 300¥Øand 600¥Ø
characteristic impedances For through hole applications.
SIP and DIP Long life and temperature stability is achieved with Ni-Cr thin film
and alumina substrates. The TFA series
will be useful in isolation circuits, data transmission, mobiles, RF
applications and measurements.
