General Information
The Bourns
®
Model CDDFN2-T3.3LC low capacitance device provides ESD, EFT and
surge protection for external ports of electronic devices such as cellular phones,
handheld electronics and other portable electronic devices.
The device measures 1.0 mm x 0.60 mm x 0.55 mm and is available in a DFN-2
package and is intended to be mounted directly onto an FR4 printed circuit board.
The device will fi t a 0402 footprint.
The device is designed to meet IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and
IEC 61000-4-5 (Surge) protection requirements.
