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 of 55 C is not exceeded.

However, the products may be operated up 55 C, if the tradeoff through decreased drift stability is acceptable to the specific application. 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 of 25 C or 55 C respectively is not exceeded. The specification of this product is based on a test board according to EN 44, providing a thermal resistance of approximately 22 K/W. 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. The IECQ-CECC approved product versions EN83 E and OMM24 EN83 E respectively feature a quality factor Q = 3 for the purpose of system MTBF calculations, compared with Q = for the standard versions. ** Please see document Vishay Material Category Policy : www.vishay.com/doc?9992 www.vishay.com For technical questions, contact: melf@vishay.com Document Number: 24 3 Revision: 6-Sep- THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?9

D K MASS (mg) OMM24 3.6 + /-.5.4.75 D + /-.5.85 + /-.35 8 s Color code marking is applied according to IEC 662 in four bands for 5 % tolerance, or in five bands. Each color band appears as a single solid line, voids are permissible if at least 2 / 3 of the band is visible from each radial angle of view. The last color band for tolerance is approximately 5 % wider than the other bands. The color of the body coating is light green for jumpers and for a temperature coefficient of ± 5 ppm/k or of ± ppm/k, pink for ± 25 ppm/k, or violet for ± 5 ppm/k. Zero ohm jumper are marked with one centered black band.
