CM1442: EMI Filter with ESD Protection
The CM1442 is a six or eight channel low-pass EMI filter array with ESD protection that reduces EMI/RFI emissions while providing robust protection from ESD strikes. Each EMI filter channel integrates a high quality pi-style filter (15pF-100 Ohm-15pF) which provides greater than 30dB of attenuation in the 800MHz to 2.7GHz frequency range. The parts include avalanche-type ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD protection diodes connected to the filter ports safely dissipate ESD strikes of ±15kV, beyond the maximum requirement of the IEC61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±30kV.
Features- 15kV ESD protection on each channel (IEC 61000-4-2 Level 4, contact discharge)
- Excellent attenuation of noise in the wireless carrier bands
- Supports clocks frequencies up to 24 MHz
| Benefits- Protects against the most agressive ESD events
- Suppressed EMI assists in improving handset performance in Total Isotropic Sensitivity testing, a requirement to get agency and carrier approvals
- Offers Electro Magnetic Noise suppression with excellent signal integrity
|
Applications- EMI filtering for data ports in cell phones, PDAs or notebook computers
| End Products- Cellular Phones, Smart Phones, Netbooks, Notebooks, Portable Navigation Devices
