Component Adhesion
(PUSH TEST)
The component should be reflow soldered onto a P.C. Board
(230°C 20 seconds) using a dynameter force gauge apply force
to any side of the component.
The component must withstand a minimum
force of 1 Kg for Pt/Ag termination and 2 Kg
for Mo/Mn termination without any failure of
the termination to component attachment.
Thermal Shock Test
Each cycle should consist of 30 minutes at -40°C followed by
30 minutes at +85°C with a 20 second maximum transition time
between temperature extremes. Test duration is 10 cycles.
Change In Inductance:
No more than 5%
Change in Q:
No more than 10%
Solderability
Dip pads in flux and dip in solder pot (63Sn/37Pb)
at 230°C ±5°C for 5 seconds.
A minimum of 95% of the metalized area
being covered with solder.
Resistance to
Soldering Heat
Dip the components into flux and dip into solder pot containing
63Sn/37Pb at 260°C ±5°C for 5 seconds ± 1 second.
Change In Inductance:
No more than 5%
Change In Q:
No more than 10%
Vibration (Random)
Inductors should be randomly vibrated per NAVMAT
P9492 profile. Sample should be subjected to 10-2,000 Hz:
0.04 G/Hz for a minimum of 15 minutes per axis
for each of three axes.
Change In Inductance:
No more than 5%
Change In Q:
No more than 10%
Moisture Resistance
Inductors should be stored in the chamber at 45°C

are to be tested after 2 hours at room temperature.
Change In Inductance:
No more than 5%
Change In Q:
No more than 10%
Cold Temperature Storage
Inductors should be stored at a temperature of -40°C
for ±2 hours. Then it should be subjected to standard
atmospheric conditions for 1 hour. After that, measurement
should be made.
Change In Inductance:
No more than 5%
Change In Q:
No more than 10%.
High Temperature Storage
Inductors should be stored at a temperature of 125°C
± 2°C for 48 ± 2 hours. Then it should be subjected to
standard atmospheric conditions for1 hour. After that,
measurement should be made.
Change In Inductance:
No more than 5%
Change In Q:
No more than 10%.
High Temperature

Inductors should be stored in the chamber at 85°C
for 1000 hours with rated current applied. Inductors should be
tested at the beginning test for 500 hours, 1000 hours, and then
Inductors are to be tested after 2 hours at room temperature.
Change In Inductance:
No more than 5%
Change In Q:
No more than 10%.
