The limit of acceptance was a shift in resistance of less than 1% from the initial value. The power applied was subject to the restrictions of the maximum permissible impulse voltage graph shown. Continuous load due to repetitive pulses: The continuous load graph was obtained by applying repetitive rectangular pulses where the pulse period was adjusted so that the average power dissipated in the resistor was equal to its rated power at 70°C. Again the limit of acceptance was a shift in resistance of less than 1% from the initial value. Pulse Withstanding Chip Resistors Pulse Performance Data

Ordering Data 25° 70° 155° 100 % Of Rated Po we r Temperature in °C Power Derating Data Construction: Thick film resistor material, overglaze and organic protection are screen printed on a 96% alumina substrate. Wrap-around terminations have an electroplated nickel barrier and tin-lead solder or matte-tin finish, ensuring excellent \`leach´ resistance properties and solderability. Marking: Components are not marked. Reels are marked with type, value, tolerance, date code and quantity. Solvent resistance: The body protection is resistance to all normal industrial cleaning solvents suitable for printed circuits.
