Bourns® Resistive Products

Selecting the Right Resistor for Your Application

Introduction

CR Series

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

CR Series

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.

When more precision is desired, Bourns® CRT series provides tight tolerance and high precision over

a wide range of resistance values. These resistors are typically used in current sense applications and

precision circuits, with specific ordering characteristics for size and performance selection.
