Vishay UMB 0207 series ultra-precision thin-film MELF resistors are first in the industry to offer TCR down to ±5ppm/K and tolerances down to ±0.02% in the standard 0207 case size, for applications requiring high stability and reliability.
The 0207 case size of this latest series is equivalent to the 2512 flat-chip size, or metric CECC size RC 6123M. The cylindrical construction provides an optimal power rating and pulse-load capability in relation to mounting space, making MELF resistors the preferred choice for applications requiring long-term stability, moisture resistance, reliability and the ability to withstand temperature cycling.
By providing the most advanced level of precision and stability ever achieved with axial thin-film high-precision resistors, combined with the proven reliability of professional MELF products, the UMB 0207 series is ideal for use in precision circuits and equipment used in harsh environments.
The UMB 0207 series spans the resistance range from 100Ω to 390kΩ, delivering the benefits of a high operating voltage of 350V, rated power dissipation to 400mW at 70°C, and long-term stability within 0.02% after 1000 hours.
