Threaded Style Filter Installation
The most common cause of failure for threaded mount filters is improper installation. Please use the following guidelines when installing filters to insure years of error-free service.
1. Do not exceed the recommended mounting torque specification shown in the table below.
2. The use of 60/40 RMA solder is recommended for attachment to terminal. Soldering iron tip temperature should be maintained at 500° F and soldering should be completed in 3 to 5 seconds. When possible, use a heat sink between terminal and filter body.
3. Avoid twisting, bending, or applying unnecessary forces on the terminal. If cutting is required it should be done prior to mounting in a manner that would apply minimum stress on the unit.
