Santa Clara, Calif. OnChip Devices has introduced a family of electromagnetic interference (EMI) filter arrays with on-board electrostatic discharge (ESD) protection in a variety of TDFN and uDFN package options. Specifically designed for high-speed data interfaces in mobile phones, this EMF110x family is offered in 4-channel, 6-channel and 8-channel filter arrays.
The EMF110x series, which includes the EMF1100, EMF1101, EMF1102, and EMF1103 devices, is said to deliver excellent S21 characteristics with extremely low parasitic inductance of 10 pH due to the package ground pad. These devices are capable of attenuating unwanted signals over the RF band between 800 MHz and 2.9 GHz. The EMF110x provides ESD protection up to +/-15 kV contact discharge per IEC61000-4-2 Level 4 specifications.
Each EMF110x device features an application-specific cut-off frequency (105 MHz to 210 MHz) and is optimized for LCD displays and camera interfaces. The TDFN package has a thickness of 0.75 mm and is offered in both the 0.4-mm and 0.5-mm pad pitch. The uDFN package has a thickness of 0.5 mm and a pad pitch of 0.4 mm.
Pricing: Ranges from $0.09 to $0.21, depending on the package type and the number of filter channels for production volumes.
