M25SI 1206 RR3216M 5 Ω to 3.9 kΩ ± 5 % (2) ± 100 ppm/K 0.250 W PxR 125 °C -55 °C to 125 °C > 300 V ≤ 1 x 10-9/h APPLICATION INFORMATION When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal resistance of the assembled resistor together with the printed circuit board. 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.

PACKAGING P5 P5 PACKAGING P5 Revision: 11-Nov-15 2 Document Number: 20031 For technical questions, contact: thinfilmchip@vishay,com THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 www.vishay.com DESCRIPTION Production is strictly controlled and follows an extensive set of instructions established for reproducibility. A homogeneous film of metal alloy is deposited on a high grade ceramic substrate Al2O3. Specially designed inner contacts are deposited on both sides. A special laser is used to achieve the target value by smoothly cutting a meander groove in the resistive layer without damaging the ceramics. The resistor elements are covered by a protective coating designed for electrical, mechanical and climatic protection. The terminations receive a final pure tin on nickel plating. The result of the determined production is verified by an extensive testing procedure. Only accepted products are laid directly into the paper tape in accordance with IEC 60286-3 Type 1a (1). ASSEMBLY The resistors are suitable for processing on automatic SMD assembly systems. They are suitable for automatic soldering using wave, reflow or vapor phase as show.
