Notes:
1.
The frequency fC is defined as the midpoint between the 3dB
frequencies.
2.
Unless noted otherwise, all measurements are made with the filter
installed in the specified test fixture that is connected to a 50Ω test
system with VSWR ≤ 1.2:1. The test fixture L and C are adjusted
for minimum insertion loss at the filter center frequency, fC. Note
that insertion loss, bandwidth, and passband shape are dependent
on the impedance matching component values and quality.
3.
Unless noted otherwise, specifications apply over the entire
specified operating temperature range.

Environmental Characteristics
Item
Condition of Test
Requirements
Random Drop
The Filter shall be measured after 3 times random drops from the height of 30cm on
concrete floor.
Vibration
The Filter shall be measured after being applied vibration of amplitude of 1.5mm with
10Hz to 55Hz bands of vibration frequency to each of 3 perpendicular directions for 1
hour.
Lead Pulling Test
A weight of 3kg is pulled towards an axis of each terminal for 10 seconds.
Lead bending Test
Lead shall be subject to withstand against 90 bending at its stem. This operation shall
be done toward both directions.
Resistance to
Soldering Heat
Lead terminals are immersed up to 1.5mm from the Filter’s body in solder bath of
270°C ± 10°C for 10 ± 1 seconds, and then the Filter shall be measured after being
placed in natural condition for 2 hour.
Solderability
Lead terminals are immersed in resin for 5 seconds and then immersed in soldering
bath of 270°C ± 10°C for 2 ± 0.5 seconds.
High Temperature
Storage
After being placed in a chamber with +85°C ± 2°C for 96 ± 4 hours and then being
placed in natural condition for 2 hour. The Filter shall be measured.
Low Temperature
Storage
After being placed in a chamber with -40°C ± 2°C for 96 ± 4 hours and then being
placed in natural condition for 2 hour. The Filter shall be measured.
Humidity
After being placed in a chamber with 90 to 95% R.H. at +40°C ± 2°C for 96 ± 4 hours
and then being placed in natural condition for 2 hour. The Filter shall be measured.
Heat Shock
After being kept at room temperature, the Filter shall be placed at temperature of
-40°C for 30 minutes, and then the Filter shall be immediately placed at temperature
of 85°C, after 30 minutes at temperature of 85°C, the Filter shall be returned to -40°C
again. After 5 times above cycles, the Filter shall be returned to room temperature,
after 2 hour in natural condition, the Filter shall be measured.
No visible damage and the
measured values shall
remain the Electronic
Characteristics after tests.
