Amp_Ah_ee_ron_spo_acl_e ^{Filter Selection Data}
Amphenol^® EMI Connectors are produced with several types of filters.
They are all low band pass filters with the following configurations:
Pi -
Typical of the VHF, UHF and MF filter
Cascaded Pi -
Typical of the HF filter. It consists
of two VHF Pi filters on a common
pin and is available in tubular
designs only.
Capacitor *-
Consists of a feed-through capacitor without any ferrite.
It can be 50pf to 1µf and carry the MF, HF and
VHF designation depending on its typical 50dB
performance.
L-C *-
Typical of HF, VHF and UHF filter.
Low source /
high load impedance.
C-L *-
Typical of HF, VHF and UHF filter.
High load impedance /
low source.
T *-
Typical of HF, VHF and UHF filter.
Low source /
low load impedance.
* Consult factory for attenuation performance values.
