Series E (ESD/EFT)
Transient Protected Connectors
These fully integrated connectors and adapters provide
protection from Electro Static Discharge (ESD) and
Electronically Fast Transients (EFT) that can damage
or even destroy your equipment. The connectors are
designed to meet various IEC 61000-4-21, EN 61000-4-2
and IEC 61000-4 standards, and are offered in a wide
range of clamping voltages to fit your specific application.
The connectors have integrated ESD transient voltage
suppressors from Littelfuse®, are available in industry
standard sizes and are “drop in” replacements for
unprotected connectors.

They are available with various capacitance levels to
condition your signals to handle EMI issues at the same
time or with as little as a 0.05 pF to protect the integrity of
your signal in high speed or digital applications.

Features
I
ESD/EFT protection at the I/O ports – Prevents the
transients from entering the system before they can
cause harm or create EMI problems.
I
Low ground impedance – The metallic shell provides
minimal impedance to direct the damaging transient
spikes to ground, which is essential for proper protection.
Potential Voltage
Overshoot Voltage
I
Removal of ground traces from the board –
This eliminates potential line-to-line noise problems
and spark-overs between ground and signal lines.

I
Complete protection – All lines, including ground
lines, have bi-directional protection.

I
Efficient space utilization – Standard footprints save
valuable board space in terms of not only components,
but also extra ground traces.

Time
I
Fewer components – Reduces total number of
components purchased, stocked, placed and tested;
yielding the savings of all the hidden costs involved
in these activities, while reducing your supplier base.
