The CS1812 is a family of p-type EMI filter array devices with integrated electrostatic discharge (ESD) protection. The CS1812 has a cut-off frequency at -3dB attenuation of 110MHz and is ideal for applications with high data rates up to 44Mbps. CS1812 guarantees better than -35dB (typical) attenuation over desired frequency range and achieves high rejection at critical frequencies, e.g., -35dB at 800MHz and -40dB at 1GHz (typical), respectively. CS1812 ensures EMI filtering and ESD protection simultaneously for high-speed data ports and control lines, such as LCD display and camera interfaces in mobile handsets.

The integrated ESD protection diodes provide robust ESD protection of ±15kV (contact) under IEC 61000-4-2and ±30kV Human Body Model (HBM) per MIL-STD-883 (Method 3015).

The CS1812 comes in space saving, low profile,0.40mmpitch uDFN package and is available in lead-free packaging.
