Resistors

Current Sensing & Low Resistance Resistors (129)

Low-ohmic resistors used as the sensing element, where the voltage across a known resistance is the measurement. Four-terminal construction, low temperature coefficient and low thermal EMF keep a milliohm-level reading honest. Specified as shunts in battery and power supply monitoring.

Precision / Ultra-Precision Resistors (126)

Resistors specified by tolerance, temperature coefficient and long-term stability rather than by power rating. Used in instrumentation front ends, references and calibration circuits, where drift over years is the property that decides the design.

Load Banks (89)

Resistive load banks that dissipate a controlled amount of power so a supply or converter can be tested under load. Rated by continuous power, resistance range and cooling method.

Non-Magnetic Resistors (64)

Resistors made without ferromagnetic material, so they neither distort a magnetic field nor move within one. Intended for magnetic resonance imaging, precision instrumentation and any assembly sitting inside a measured field.

Z Foil resistors (56)

Bulk metal foil resistors, holding temperature coefficient, load-life drift and thermal EMF to very low levels, with coefficients down to ±0.2ppm/°C on selected series. Used in metrology, automatic test equipment and space-qualified work.

High-Temperature Resistors (36)

Resistors qualified for high ambient and high surface temperature, in precision and power constructions. Derating curve, terminal material and mounting method carry more weight here than the room-temperature specification.

Power Resistors (33)

Resistors for higher dissipation, in several mounting styles and across a wide resistance span. The thermal path is as much part of the specification as the resistance value, because the rating depends on how the heat leaves the part.

Networks & Voltage Dividers (22)

Resistor networks and voltage dividers where the ratio between elements matters more than the absolute value. Matched and tracking configurations hold that ratio across temperature, for references, instrumentation amplifiers and precision measurement.

High-Voltage Resistors (21)

Resistors rated by voltage as well as by power, for measurement dividers, discharge paths and high-voltage supply control. Creepage, tracking resistance and voltage coefficient are the properties that decide whether the part survives the application.

Standard Resistors (9)

General-purpose resistors in common values, tolerances and packages, for the parts of a design where the resistor is not the critical element.

Thermosensitive Resistors (7)

Resistors whose resistance changes predictably with temperature, used deliberately as a compensating element rather than held stable against it. For temperature measurement, bias compensation and thermal protection in analogue and power circuits.
