Product Overview CSPEMI201A: EMI Filter with ESD Protection, Headset Speaker For complete documentation, see the data sheet Product Description The CSPEMI201AG is a dual low-pass filter array integrating two pi-style filters (C-R-C) that reduce EMI/RFI emissions while at the same time providing ESD protection. This part is custom-designed to interface with a speaker port on a cellular telephone or similar device. Each high quality filter provides more than 35dB attenuation in the 800-2700 MHz range. These pi-style filters support bidirectional filtering, controlling EMI both to and from a speaker element. They also support bipolar signals with a cutoff frequency of 31MHz, enabling audio signals to pass through without distortion. Features Benefits • Two lines of EMI suppression with integrated ESD protection • Suppresses noise off of strong analog and digital audio lines, provides ESD protection in a monolythic Chip Scale Package • Using Chip Scale Packaging to eliminate the long wires associated with packaging • Extremely low lead inductance for optimum filter and ESD performance Applications End Products • Audio interfaces on wireless devices • Cellular phones, notebook computers, netbook computers, portable navigation devices Part Electrical Specifications Product Compliance Status Interface Number of Lines Filter Type R Typ (Ω) C Typ (pF) IR Max (µA) V(BR) Typ (V) VRWM Max (V) Package Type CSPEMI201AG Pb-free Active General I/O 2 R-C 200 6.8 5 WLCSP-5 Halide free 10 For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016 1
