The WRM Series MELF resistors from TT Electronics are designed for high reliability and defined pulse handling capability. They are AEC-Q200 qualified and available with tolerances down to 0.1% and TCRs down to 5ppm/C. All parts are Pb-free and comply with EU Directive 2011/65/EU amended by (EU) 2015/863 (RoHS3). These resistors feature a metal film deposited on a high dissipation ceramic former, adjusted by a helical cut, and protected by a lacquer coating. They are suitable for various applications requiring precise resistance values and stability.
