Exxelia Ohmcraft can screen and qualify its resistor products to MIL-PRF-55342, MIL-PRF-49462, NASA EEE-INST-002 (Level 1 or Level 2) or a custom test plan. LAT Testing includes but is not limited to:
| Value R | R Ω | Resistance Value in kΩs, MΩs, GΩs, or TΩs |
| Tolerance | ± X% at V | Resistance Tolerance measured at specified voltage |
| TCR | < [Ordering Coder TCR] ppm/ºC (Hot to TmaxºC, Cold to TminºC) < 2*[Ordering Coder TCR] ppm/ºC (Hot to 125ºC, Cold to -55ºC) | TCR referenced to 25ºC |
| Working Voltage | V | Voltage across the resistor during application operation |
| Max Voltage Rating | V | Maximum Voltage based on resistance value or case rating |
| Max Power Rating | W | Maximum Wattage based on resistance value or case rating |
