Datasheet
## **Features** ■ RoHS compliant* - ESD protection >25 kV - Low capacitance <0.5 pF - Low leakage current <50 nA ## **Applications** ■ HDMI 1.4 - Digital Visual Interface (DVI) - USB 3.0 / USB OTG - Memory protection - ■ SIM card ports ## BOURNS ~~Ee~~ **ChipGuard[®] MLC Series - ESD Protectors** ## ~~**General Information**~~ The ChipGuard[®] MLC Series has been specifically designed to protect sensitive electronic components from electrostatic discharge damage. The MLC family has been designed to protect equipment to IEC61000-4-2, Level 4 (±8 kV Contact / ±15 kV Air Discharge) ESD specifications targeted for high speed USB 3.0/USB OTG, HDMI 1.4, DVI or IEEE1394 applications. The ChipGuard[®] MLC Series has been manufactured to provide low 0.5 pF capacitance and leakage currents less than 5 nA with excellent clamp qualities, making the family almost transparent under normal working conditions. ## ~~**Additional Information**~~ Click these links for more information: **==> picture [148 x 13] intentionally omitted <==** **----- Start of picture text -----**<br> PRODUCT TECHNICAL INVENTORY SAMPLES CONTACT<br>SELECTOR LIBRARY<br>**----- End of picture text -----**<br> **==> picture [61 x 9] intentionally omitted <==** **----- Start of picture text -----**<br> Device Symbol<br>**----- End of picture text -----**<br> **==> picture [10 x 11] intentionally omitted <==** **----- Start of picture text -----**<br> V<br>**----- End of picture text -----**<br> ## ~~**Electrical Characteristics @ 25 °C (unless otherwise noted)**~~ ~~PT~~ **CG0402MLCParameter Symbol Unit** ~~e~~ **3.3LG 05LG** ~~e~~ **12LG 24LG 3.3LGA 05LGA** ~~eo~~ **12LGA** ~~eee~~ **24LGA** ~~OC~~ Typical Continuous Operating Voltage VDC 3.3 5 12 24 ~~‘~~ 3.3 5 12 24 V ~~a~~ Typical Clamping Voltage (Note 1) VC ~~P~~ U ~~UU UO~~ 25 V ~~a~~ Maximum Capacitance @ 1 VRMS 1 MHz CO 0.5 pF ~~a~~ Maximum Leakage Current @ Max.
