TO resistor -Thermal resistance and beyond
Heat dissipation is a key factor in the design of a power system; in a world where the trend is for more power in a smaller space, are TO-style packages still the best solution? TO packages were originally intended for discrete transistors, in fact TO stands for...
Resistor orientation and the thermal EMF effect
Maintaining a constant temperature around precision resistors is integral to maintaining the stability of a circuit. Even small fluctuations in the temperature of a resistor can cause errors in a circuit due to noise. The relationship between temperature and...
Measuring Tiny Resistances Accurately when using resistors
Digital multi-meter When measuring the resistance of something is a great deal more complicated if that resistance is very small. With bigger resistances, measurements can be as simple as connecting two leads between a digital multi-meter (DMM) and the device under...
Why is a Wirewound Resistor not a Wirewound Inductor?
We can make a wirewound resistor by winding resistive wire into a coil around an insulating core. We can also make an inductor by using a more conductive wire and winding it around a ferrite core. Both are essentially a coil of wire around a core, so what makes...
Precision Resistors for the Gigaohm-Range
High Value Resistors with specified properties at small sizes To analyze very low electronic signals, resistors with extremely high values are required. Based on a long tradition of working in this niche market, SRT Resistor Technology GmbH in Cadolzburg/Germany has...
Non-magnetic Chip Resistors and Chip Capacitors
Chip Resistors for High Temperature Applications The special technological aspects of these components produced by Riedon, Inc. are the materials of the contact areas, which contains no Nickel, so they are nonmagnetic. The contact areas are made by noble metal alloys...

Wirewound Temperature Sensing
Wirewound Temperature Sensing Resisors Many of Riedon’s Temperature sensing Wirewound products are available in special high Temperature Coefficients of Resistance (TCR), ideal for use in temperature sensing applications. Wirewound temperature sensors provide the most...
Thin Film Resistor Construction and Properties
Thin Film Resistors Thin film resistors are built on a ceramic base, with the resistive layer sputtered on top using vacuum deposition to create a chip resistor. The material used is commonly an alloy of nickel and chrome called Nichrome. The thickness of the film...
Thick Film Construction and Properties
Thick Film Resistors Thick film resistors have many carbon resistor characteristics; they can be made small and are very low cost in high quantities. Their resistance tolerance, TCR and stability over time is not as favorable as wirewound or foil types, but they have...
