Unless noted otherwise, all specifications apply over the operating temperature range with filter soldered to the specified demonstration board with impedance

matching to 50

Ω

and measured with 50

Ω

network analyzer.

Unless noted otherwise, all frequency specifications are referenced to the nominal center frequency, fc.

Rejection is measured as attenuation below the minimum IL point in the passband. Rejection in final user application is dependent on PCB layout and external

impedance matching design. See Application Note No. 42 for details.

"LRIP" or "L" after the part number indicates "low rate initial production" and "ENG" or "E" indicates "engineering prototypes."

The design, manufacturing process, and specifications of this filter are subject to change.

Either Port 1 or Port 2 may be used for either input or output in the design. However, impedances and impedance matching may vary between Port 1 and Port

2, so that the filter must always be installed in one direction per the circuit design.

US and international patents may apply.

Physical and Environmental Characteristics

Test Item

Test Condition

Filter is soldered onto the center of 0.8mm thickness PCB which is laid

on the two small supporters spaced 90mm as shown in below figure.

PCB is deflected to 2mm below from horizontal level by the pressing

stick. The force is supplied for 1 second - 5 times repeatedly.

Criteria

No visible damage should

be induced.

PCB Bend Strength

Vibration

The electrical performance is measured after being applied vibration

of amplitude of 1.5mm with 10 to 55Hz of vibration frequency to each

of 3 perpendicular directions for 2 hours.

The electrical performance is measured after dropping with housing

(around 100g) from a height of 150cm onto the concrete plate 3 times

in each of 6 perpendicular directions.

Terminals are immersed in rosin flux (concentration 20...25%, solvent:

ethanol 75...80%) for 5 seconds, then immersed in soldering bath at

230±5°C (solder: JIS-Z-3282 H63A, H60A or Sn-3.0Ag-0.5Cu) for

5±0.5 seconds.

Filter is preheated at 170±10°C for 90 seconds, immersed whole elec-

trode in soldering bath at 255±5°C for 3±1seconds, then measured

after being placed in standard atmospheric conditions for 2 hours.

The electrical performance is measured after being placed in a cham-

ber with 90...95% R.H. at 60°C for 500 hours and then being placed in

standard atmospheric conditions for 2 hours.

The electrical performance is measured after being placed in a cham-

ber with 85°C for 500 hours and then being placed in standard atmo-

spheric conditions for 2 hours.

The electrical performance is measured after being placed in a cham-

ber with -40°C for 500 hours and then being placed in standard atmo-

spheric conditions for 2 hours.

After temperature cycling of -55°C for 30 minutes to +85°C for 30 min-

utes performed 100 times, filter shall be returned to room temperature.

And the electrical performance is measured after being placed in stan-

dard atmospheric conditions for 2 hours.

The electrical performance is measured after being soldered by reflow

2 times with the following reflow profile A or B and then being placed in

standard atmospheric conditions for 24 hours.

90% minimum of the

immersed surface should

be covered with solder.
