Description

Temexpress proposes for your applications standard Monolithic Crystal Filters with:

  • Good intermodulation characterics
  • High reliability
  • High stability of parameters
  • Resistance of environmental factors meeting the IEC standard
Temexpress offers all standard frequencies of 10.7, 21.4, 45, 70 and 90MHz in all the common bandwidth configurations.

  10.7MHz – Monolithic crystal filters – Through Hole Package
  21.4MHz – Monolithic crystal filters – Through Hole Package
  21.4MHz – Monolithic crystal filters – SMD Package
  45MHz – Monolithic crystal filters – Through Hole Package
  45MHz – Monolithic crystal filters – SMD Package
  70MHz – Monolithic crystal filters – Through Hole Package
  70MHz – Monolithic crystal filters – SMD Package
  90MHz – Monolithic crystal filters – Through Hole Package
  90MHz – Monolithic crystal filters – SMD Package

Temexpress MCFs part numbers are made up in the following manner:

QEF + Type of package + frequency + number of poles + passband width
• QEF : generic product family
• Type of package : blank for Through hole type or S for SMD type
• Frequency: in MHz with one decimal (e.g. 21M4 for 21.400MHz)
• Number of poles : A for 2; B for 4; C for 6; D for 8
• Passband width: total passband width at 3dB

For example : MCF @21.4MHz, 2 poles, passband @3dB: ±7.5KHz is QEF21M4A15


Features

All Temexpress Xtals Filters are RoHS compliant.
