PROTECTION PRODUCTS - EMIClampTM
Description
The EClampTM2422N is a (C-L-C) low pass filter array with
integrated TVS diodes. It is designed to suppress
unwanted EMI/RFI signals and provide electrostatic
discharge (ESD) protection in portable electronic
equipment. This state-of-the-art device utilizes solid-
state silicon-avalanche technology for superior clamp-
ing performance and DC electrical characteristics. It
has been optimized for protection of headset
audio ports in cellular phones and other portable
electronics.
The device consists of two identical circuits comprised of
TVS diodes for ESD protection, and a C-L-C pi-filter for
EMI/RFI filtering. A typical inductor value of 2nH and a
capacitor value of 100pF are used to achieve 20dB
minimum attenuation from 800MHz to 2.7GHz. It has a
very low series resistance of 2 Ohms, making it ideal for
use on headset speaker interfaces. The TVS diodes
provide effective suppression of ESD voltages in excess of
±15kV (air discharge) and ±8kV (contact discharge) per
IEC 61000-4-2, level 4.
The EClamp2422N is in a 6-pin, RoHS/WEEE compliant,
SLP1510N6 package. It measures 1.45 x 1.0 x
0.58mm. The leads are spaced at a pitch of 0.5mm
and are finished with lead-free NiPdAu. The small
package makes it ideal for use in portable electronics.
