onsemi CM1443 08CP 8 channel EMI filter array featuring Pi style filter network and robust ESD protection
Product Overview
The CM1443-08CP is an 8-channel EMI filter array with integrated ESD protection, designed for data and I/O ports. It features a Pi-style EMI filter network (Capacitor-Resistor-Capacitor) for each channel, providing effective filtering against electromagnetic interference. The device offers robust ESD protection up to 15 kV (IEC 61000-4-2 Level 4, Contact Discharge) and 30 kV (HBM). Its Chip Scale Package (CSP) with a 0.4 mm pitch and 3.160 x 1.053 mm footprint ensures extremely low lead inductance for optimal performance. The OptiGuard coating enhances reliability during assembly. This Pb-free and RoHS-compliant component is suitable for applications such as wireless handsets, handheld PCs/PDAs, MP3 players, notebooks, and desktop PCs.
