CERAMIC FILTER LTS_MCB
Ceramic discriminators for AM applications:
SMD type for reflow soldering (JTBC)
AUDIO IF APPLICATIONS
§
Leaded type (JTBM)
PHYSICAL CHARACTERISTICS
Random Drop Test:
Filter performance shall be tested after
3 x random drop from 1.0metre onto
concrete floor. No visible damage
should be observed and the measured
values shall be within specification.
Filte shall be measure after being
applied with vibration, amplitude
1.5mm, frequency 10Hz to 55Hz for 2
hours in each of the 3 perpendicular
planes. The measured electrical values
shall be within specification.
Lead terminals are immersed up to
2.0mm from the filter body in a solder
bath (350° ±10°C for 5±0.5 seconds).
The filter should be measured after
being in room temperature for 1 hour.
Lead terminals are immersed in resin
for 5 seconds then immersed in a
soldering bath at 250°C±5°C for 3
seconds ±0.5 seconds. A minimum of
95% of lead terminals surface shall be
covered with solder.

ENVIRONMENTAL SPECIFICATION
High Temperature:
After being placed in a chamber at
+85°±2°C for 96 hours and left for one
hour at room temperature the
measured values are to be within
specification.
After being placed in a chamber at
-25°±2°C for 96 hours and left for one
hour at room temperature the
measured values are to be within
specification.
After being placed in a chamber with a
humidity of 90~95% RH and a
temperature of +40° for 96 hours and
left for one hour at room temperature
the measured values are to be within
specification.
After being kept at room temperature
the filter shall be placed at a
temperature of -25°C. After 30 minutes
at the temperature the filter is
immediately placed at a temperature of
+85°C. After 30 minutes the filter is
again placed at a temperature of -25°C.
This is one cycle. The filter is subjected
to 5 cycles. After one hour at room
temperature the measured values are to
be within specification.
