"R" level screening is performed by Spectrum Control's
Hi-Rel Laboratory as detailed below. Customers requiring
special tests may order to their own specifications or simply
order to level R and then note additions or deviations.
"R" Level Test Sequence Summary
(100% testing unless otherwise specified)
Thermal Shock: 5 cycles from -55°C to +125°C in
accordance with MIL-STD-202, Method 107D,
Condition A.
Burn-in: 100 hours at 1.4x rated DC voltage, 125°C.
Seal Test: MIL-STD-202, Method 112, Test Condition A.
Hermetic seal parts only.
Capacitance and Dissipation Factor: MIL-STD-202,
Method 305, frequency 1kHz.
Dielectric Withstanding Voltage: 2.5 times the rated DC
voltage for 5 ± 1 second at 25°C, with 50 mA maximum
charging current.
Insulation Resistance: MIL-STD-202, Method 302,
125°C at rated DC voltage and room temperature
(25°C). The 125°C requirement shall be 10% of the
specified catalog IR at 25°C.
DC Resistance: MIL-STD-202, Method 303.
Insertion Loss Test — Sample per MIL-F-15733.
At full rated load in accordance with MIL-STD-220.
The minimum insertion loss shall be defined in the
filter catalog.
Visual and Mechanical: in accordance with MIL-F-15733.
Marking: All filters which have successfully completed
the test sequence shall be marked with an "R" in the
second part of the number. For example, a standard
SCI-2130-004 becomes SCI-R2130-004 and 9051-100-
0000 becomes 9051-R100-0000, and 51-719-011
becomes 51-R719-011 after completion of the Hi-Rel
Level "R" Test Sequence.
