The Syfer range of varistor filters provides both transient voltage protection and EMI filtering in one device. The heart of this
unique device is a multilayer varistor discoidal, which provides a dual function. The use of metal oxide based ceramic (MOV)
provides the voltage protection, with bi-directional clamping, while the inherent capacitance, due to the multilayer construction,
ensures effective lowpass EMI filtering up to at least 1GHz.
Maximum continuous dc working voltage
This is the maximum continuous dc working voltage which
may be applied up to the maximum operating temperature of
the varistor.
Nominal voltage
This is the voltage across the varistor when drawing a dc
current of 1mA. It is this point that is notionally the start of
the region of normal varistor operation.
Maximum clamping voltage
As a varistor is designed for handling transient voltages, all
tests requiring currents in excess of 1mA are conducted as
pulse tests.
The clamping voltage of a varistor is the peak voltage
appearing across the device when measured under the
conditions of a specified pulse current and a specified
waveform.

The Syfer balanced line filter is a 2-pin panel mounting device suitable for balanced lines and twisted pairs. It is ideal for passing
lines through a bulkhead, and the feedthrough construction offers insertion loss performance up to 1GHz and above. The filter
also incorporates capacitance line-to-line as well as line-to-ground, and therefore both differential and common mode filtering are
offered in the same package. In this way one single device can replace three separate components.

Ceramic filter element manufactured in the UK by Syfer Technology Limited under
licence from X2Y attenuators LLC.
