The CS1802 is a family of p-type EMI filter array devices with integrated electrostatic discharge (ESD) protection. The CS1802 has a high roll-off frequency at -6dB attenuation of 400MHz and is ideal for applications with high data rates up to 160Mbps. CS1802 guarantees better than -25dB (typical) attenuation over desired frequency range and achieves high rejection at critical frequencies, e.g., -30dB at 1GHz and -40dB at 2GHz (typical), respectively. CS1802 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 61000-4-2 and ±30kV Human Body Model (HBM) per MIL-STD-883 (Method 3015).

The CS1802 comes in 0.40mm pitch uDFN package, which saves up to 42% board space compared with 0.50mm pitch uDFN packages.
