PR01, PR02, PR03 www.vishay.com Vishay BCcomponents Power Metal Film Leaded Resistors FEATURES High power in small packages (1 W / 0207 size to 3 W / 0617 size) Defined fusing characteristics Technology: metal film Meets active and passive flammability requirements as defined in IEC 60115-1 AEC-Q200 qualified (PR01 and PR02) Material categorization: for definitions of compliance please see www.vishay.com/doc 99912 APPLICATIONS DESCRIPTION All general purpose power applications A homogeneous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been cut in Automotive electronics the resistive layer, tinned connecting wires of electrolytic Lighting ballast copper or copper-clad iron are welded to the end-caps. The resistors are coated with a red, non-flammable lacquer which provides electrical, mechanical and climatic protection. This coating is not resistant to aggressive fluxes and cleaning solvents. The encapsulation is resistant to all cleaning solvents in accordance with IEC 60068-2-45.

The rated dissipation applies only if the permitted film temperature is not exceeded. Furthermore, a high level of ambient temperature or of power dissipation may raise the temperature of the solder joint, hence special solder alloys or board materials may be required to maintain the reliability of the assembly. 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 designer may estimate the performance of the particular resistor application or set certain load and temperature limits in order to maintain a desired stability.
