Resistor Thick Film, High Temperature

This specific product line is not for new designs. This family of high resistance (10M Ohms to 1 Tera Ohms) resistors employs a thick film resistive element and is designed for long term stability and low TCR (temperature coefficient of resistance) which are compatible with high volume SMT applications. TCR’s as low as +/-25ppm and tolerances as tight as +/-1% are available.
Standard EIA size packages 0402, 0603, 0805, 1206, 2512 and 4020 can handle power up to 2 Watts. These are non-magnetic resistors and thus are well suited for nonmagnetic applications.
For resistors operating in high temperature environments, we have two temperature options up to +155C or +300C. Their platinum silver terminations are designed are compatible with soldering, epoxy bonding, or wire bonding applications. The wide range of electrical and mechanical characteristics allow for design flexibility.
We can design our high temperature resistors for specific voltage requirements by trimming these thick film resistors. Contact our applications engineers to discuss high voltage or high temp ( +300C) applications.
