A resistor element includes a base substrate having first and second surfaces opposing each other and first and second end surfaces opposing each other and connecting the first and second surfaces. A first resistor layer is on the first surface of the base substrate. First and second terminals are respectively on the first and second end surfaces. A second resistor layer is on the first resistor layer, is connected to the first and second terminals, and includes a copper-manganese-tin (Cu&#x2014;Mn&#x2014;Sn)-based composition.

Resistor element and resistor element assembly

A chip resistor includes a board, first and second electrodes disposed on one surface of the board, and a resistor body electrically connecting the first and second electrodes to each other and including a copper-manganese-tin (Cu&#x2014;Mn&#x2014;Sn) alloy. In the Cu&#x2014;Mn&#x2014;Sn alloy, a percentage of Mn ranges from 11% to 20%, a percentage of Sn ranges from 2% to 8%, and a total percentage of Mn and Sn ranges from 13.5% to 22.5%.

Chip resistor

A chip resistor element includes an insulating substrate, a resistor layer, first and second internal electrodes, a resistor protection layer, first and second electrode protection layers, and first and second external electrodes. The resistor layer is on the insulating substrate, the first and second internal electrodes are on respective sides of the resistor layer, and the resistor protection layer covers the resistor layer and extends onto portions of the internal electrodes. The first electrode protection layers are on the first and second internal electrodes so as to overlap with portions of the resistor protection layer and contain first conductive powder particles and resin, while the second electrode protection layers are disposed on the first electrode protection layers and contain second conductive powder particles and resin. A content of resin in the second electrode protection layer is lower than in the first electrode protection layer.

Chip resistor element

A chip resistor includes a substrate having first and second electrodes disposed on one surface thereof to be separated from each other. A first resistor electrically connects the first electrode to the second electrode, and a second resistor electrically connects the first electrode to the second electrode. When temperatures of the first electrode and the second electrode are different from each other, thermo electromotive force generated from the first resistor is less than thermo electromotive force generated from the second resistor, and a temperature coefficient of resistivity (TCR) of the second resistor is lower than the TCR of the first resistor.

There is provided a chip resistor including a ceramic substrate; a first resistance layer formed on the ceramic substrate and including a first conductive metal and a first glass; and a second resistance layer formed on the first resistance layer, including a second conductive metal and a second glass, and having a smaller content of glass than the first resistance layer, thereby obtaining relatively low resistance and a relatively small temperature coefficient of resistance (TCR).
