CFM2/CFM3  
AM CERAMIC FILTERS  
Description  
Dimensions  
• Compact 2/3 element AM IF filter with  
unique structure for high reliability.  
• Center frequency range: 450 to 470kHz  
• Bandwidth at 6dB: 4 to 12kHz. (4~8kHz: CFM3)  
Features  
• Compact, low profile  
• High selectivity, suited to a wide range of applications  
• Low temperature coefficient  
• Low spurious response  
Unit: mm  
• Lead-free terminations  
Applications  
• AM radio cassettes, stereo sets, telecommunications  
• Wireless data communication equipment  
Test Circuit  
Test Conditions  
1. C includes test circuit capacitance. (50pF without L2, 62pF with L2)  
2. L1 2.7mH (CFM2), 1.35mH (CHM3)  
L2 1.0mH  
3. During testing, when matching coils are used at input/output sides,  
connect L1 and L2 (dummy)  
4. R1, R2: Input-output impedance  
Cs: Stray capacitance  
(less than 50pF, including EV)
