| Maximum Load at rated power (1000hrs cyclic load at 70C) | R% | 3 |
| Short term overload (6.25 x rated power for 5s) | R% | 2 (0805, 2010): 3 (1206) |
| Temperature rapid change (-55 / +155C, 5 cycles) | R% | 0.5 (1% tolerance chips): 1 (5% tolerance chips) |
| Damp heat steady state | R% | 3 |
| Insulation resistance | Ohms | >1000M |
Construction
Pd/Ag terminations are applied to the top and bottom of an alumina substrate. A resistive element is printed between the top face conductors, which is then adjusted to value and protected. A wraparound conductor is applied to join the top and bottom sides. The terminations are electroplated with a Ni barrier layer prior to plating with a Sn finish.
Solvent Resistance
The body protection and marking are resistant to all normal industrial solvents suitable for printed circuits.
Flammability
The resistor will not burn or emit incandescent particles under any condition of applied temperature or overload.
Solderability
95% min coverage (MIL-STD 202F / 208H, 235C 2 secs)
