SURFACE MOUNT INDUCTORS AND TRANSFORMERS
SG-890A
Engineering Bulletin SG-890 describes a wide range
of fixed and variable surface mount inductors, coils,
transformers and filters. Parts are wound as air coils,
or on a selection of ferrite cores, and can be used
up to the GHz frequency range.
resonant circuits. Non-tunable tapped coils and coils
with multiple windings are also required for
applications such as DC isolation,voltage and
current transformations and impedance matching
(between amplifier stages, for example).
The SURFCOIL® models operate over the professional
grade temperature of –40° to +125°C. (Sprague
Goodman’s selection of SURFCOIL SMT chip
inductors, which operate over the temperature
range of –25° to +85°C, are described in Engineering
Bulletin SG-800.)
Fixed inductors are used in all areas of
telecommunications, video and medical electronic
equipment. They are ideal in radio interference
suppression devices, filters, and decoupling of
oscillator and amplifier stages.
