RJM SERIES HIGH PRECISION SMT TYPE RESISTORS MELF TYPE METAL FILM RESISTORS, COATED TYPE Feature · Advanced thin film technology · Excellent overall stability: Class 0.05% · Extremely low TCR: up to ±5ppm/K · Exceptionally low noise and voltage coefficient • Compliant to RoHS directive 2011/65/EU • Compliant to REACH (EC No. 1907/2006)) (last updated: 27/06/2018) Description Production is strictly controlled and follows extensive set of instructions established in production procedure for reproducibility. A homogeneous film of metal alloy is deposited on the surface of high-grade ceramic cores (85%~96% AL2O3) and conditioned to achieve the desired stability and the temperature coefficients. A professional laser or an extreme thin emery wheel is pressed on the metalized rods to not only achieve the target value but also prefect electronics performance by smoothly cutting a helical groove in the resistance layer on the ceramic rods without damaging the ceramics. The resistance layers are covered by a protective coating and hard Bakelite designed for electrical, mechanical, and climatic protection. The resistors are tested in accordance with MIL-R-10509F which refers to MIL- STD-202 or IEC60115. The established reliability in accordance with CECC 40401-803 Version E is available upon request. www.thunder-resistor.com sales@thunder-resistor.com 1 1.

Derating curves The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime. For MELF resistors working at an ambiance temperature of 70 ℃ or above, the power rating shall be derated in accordance with the above curves. 7.
