Precision Chip Resistors (AR)

DeMint's thin-film precision chip resistors (AR) take accuracy pole position and add powerful new options.

In response to market demands for increased precision and stability, DeMint Passive Components has expanded its AR Series of nichrome thin-film chip resistors into three sectors, Standard, High-Precision, and High-Power resistor.

Offering a wide value range with closer tolerances and low TCR figures, DeMint offers a surface mount resistor with a defined total contour that provides high stability under temperature fluctuations of 2ppm/°C and with a tolerance down to ± 0.01%.

The AR Series offering solutions to precision test and measurement and voltage regulation across industrial, military and medical monitoring equipment markets proposing superior tight tolerance, low TCR, and high power rating performance.

The range now also offers additional chip sizes. Key features of the enhanced AR Series include the availability of all standard sizes from AR01(0201), AR02(0402), AR03(0603), AR05(0805), AR06(1206), AR13(1210), AR10(2010), to AR12(2512).

The AR benefits from an impervious internal passivation layer applied in addition to the normal protective coating. When constructing the AR Chip Series, a Ni/Cr thin-film material is selectively deposited on an alumina substrate, together with Ni and Sn metallic contacts at each end layer plating. The AR chips are heat treated to give the required temperature coefficient (TCR) and stability, and then a precisely controlled laser trim process adjusts the resistance value.

The AR Series is available in taping packaging and is RoHS compliant and lead free.
