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.

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.
