Mechanical Filter Curves

These curves I've generated represent a single example of that part number, and may not be typical.

  Ceramic Filter Curves

• Murata CFS455J
• Murata CFR455I
• Murata CFR455J
• Murata CFK455I
• Murata CFJ455K4
• Murata CFJ455K5
• Toko LF-C2A
• Toko LF-C6
• Toko LF-D6
• This is what happens to the response curve of a Toko LF-D6 if you terminate it with 2 Kohms instead of the design value 1500 ohms. Compare this to the previous chart.
