Bourns® Resistive Products
[attachment=35692]
Introduction
Science and engineering students typically experiment with axial leaded resistors,
learning a color code to identify the resistor value based on the stripes around the resistor
body. In practice, however, axial leaded resistors are overshadowed in board fabrication
by resistors for which the construction, package styles, and materials are targeted for
specific applications.
Bourns offers a wide variety of resistive products that include devices that range from
industry standard size chip resistors to very high frequency (RF) power resistors in order
to meet today’s broad market requirements. There are many advantages to incorporating
Bourns® resistors into today’s designs including custom values, miniature component
size, higher power ratings, and the highest quality materials and construction. Since it
is far more than just the resistor value that drives the decision of which resistor to use
in a circuit design, Bourns is committed to ensuring designers’ needs are met with the
company’s extensive portfolio of resistive products. In this white paper, the various types
of resistors will be briefly explained, and tables are provided as a quick reference for the
available range of resistive products.
Overview of Resistor Families
Regardless of the application, a resistor is essentially a current control, voltage drop product.
Additionally, Bourns® components can be designed to withstand unique application challenges like an
overcurrent pulse for a short duration without significant changes of resistor characteristics. Bourns®
Fixed Resistors can be defined by construction type (thick film, wirewound, etc.), the way they are
processed, (through-hole, surface mount, etc.) the intended use (current sense, high frequency, etc.),
accuracy, size, power or many other ways. Each resistor does two main things: control current and
control a drop in voltage.
Bourns also has a very broad offering of resistor network (Model 4xxx Series), in a wide selection of
industry standard models. Therefore, they can be used with an industry standard footprint for seamless
placement in printed circuit board designs.
Bourns® chip resistors are available in various package sizes, standard values and technologies
which are designed to meet most market requirements including those for specific application and
performance characteristics.
Bourns® CRL series resistors offer total resistance values less than those required by industry standards
providing engineers enhanced circuit design flexibility.
Benefits of Working with Bourns
Bourns offers standard resistors for vast applications needs, and when one is not available it
is likely that it can be created by customizing an existing, proven part. Bourns has lead in the
development and innovation of resistive products for decades and continues to expand its
product offerings based on the needs of designers and on emerging market applications. As
an example, certain applications including consumer goods require a resistor that is fuseable.
This fuseable resistor will become an open circuit during a surge to prevent the electronics
from catching fire. This is just one example of Bourns being ready to meet evolving
requirements with a high quality solution. Designers’ concerns about size, power and quality
of the component have been addressed when they select a resistor from Bourns.
