PULSE-GUARD
®
ESD Suppressors help protect sensitive
electronic equipment against electrostatic discharge (ESD).
They supplement the on-chip protection of integrated
1.27
(0.050")
circuitry and are best suited for low-voltage, high-speed
1.27
applications where low capacitance is important. Data
(0.050")
ports utilizing such high-speed protocols as USB 2.0,
IEEE1394, HDMI and DVI can benefit from this new
technology.
PULSE-GUARD
®
suppressors use polymer composite
materials to suppress fast-rising ESD transients (as
specified in IEC 61000-4-2), while adding virtually no
capacitance to the circuit.

Design Consideration
Because of the fast rise-time of the ESD transient,
proper placement of PULSE-GUARD
®
suppressors are
a key design consideration to achieving optimal ESD
suppression. The devices should be placed on the circuit
board as close to the source of the ESD transient as
possible. Install PULSE-GUARD
®
suppressors (connected
from signal/data line to ground) directly behind the
connector so that they are the first board-level circuit
component encountered by the ESD transient.
