High Frequency Ceramic Trap Filters

High Frequency Ceramic

Trap Filters

ÒV CERAPÓ

High Frequency Ceramic Filter ÒV CERAPÓ, using the

third higher harmonics of thickness vibration mode of

the piezoelectric ceramics, is recommended for

frequency trap filter in VHF band of TV and VTR.

ÒV CERAPÓ promises to make the circuit simple and

adjustment-free, featuring the large attenuation at the

specified frequency with excellent spurious suppression

characteristics.

n Recommended Applications

n Features

l Frequency Trap Filters for video intermeditate

l Conventional LC-trap filters can be replaced by

ÒV CERAPÓ

Electro-technique

l Contributes to circuit simplification because of its

adjustment-free

l Closed tolerance of the trap frequency and

excellent frequency vs. attenuation characteristics

l Low dielectric constant material is applied for easy

electrical matching in VHF

n Precautions for Safety (See Page 217)

l To meet requirements of European Regulations on

TV and VTR such as CENELEC and FTZ,

combination of SAW Filter (Band-pass Filter) and ÒV

CERAPÓ (Frequency Trap Filter) is recommended
