44 MULTI-HOLE PLATE
Explanation of Part Numbers:
– Digits 1 & 2 = Product Class
– Digits 3 & 4 = The 44 Material Grade
To provide suppression of conducted EMI at critical interfaces Fair-Rite has available a line of suppression plates that can be used with many types of connectors. All connector plates are supplied in the NiZn 44 grade ideally suited for this application because of its high impedance along with a high resistivity.
For any connector EMI suppression plate requirement not listed here, feel free to contact our customer service group for availability and pricing.
The C dimension can be modified to suit specific applications.

Chart Legend
+ Test frequency
| Typical Impedance (Ω) | |
| 25 MHz+ | 11.3 |
| 100 MHz+ | 20 |
Connector plates are controlled for impedances only.
Minimum impedance values are specified for the + marked frequencies.
The minimum impedance is listed on our catalog drawing.
Single turn impedance tests are performed on the E4990A Impedance Analyzer, using the shortest practical wire length.
| Typical Impendance (Ω) | |
| 25 MHz+ | 13 |
| 100 MHz+ | 28 |
A NiZn ferrite developed to combine a high suppression performance, from 30 MHz to 500 MHz, with a very high DC resistivity.
