Test methods are referenced to MIL-STD-883 as determined by MIL-PRF-38534.
ꢀotes:
1. Our Redmond facility has a DLA approved RHA plan for Interpoint power
products. Our SMD products with RHA “R” code meet DLA requirements.
2. “OO” prototypes are non-QML products and may not meet all of the requirements
of MIL-PRF-38534. “O” in the RHA designator position in Interpoint model
numbers indicates DLA RHA “-” defined as no RHA.
3. All processes are QML qualified and performed by certified operators.
4. ꢀot required by DLA but performed to assure product quality.
5. Burn-in temperature designed to bring the case temperature to +125°C minimum.
Burn-in is a powered test.
