Overview
The CM1461-08DE is an 8-channel EMI filter array manufactured by onsemi, designed for LCD and camera interfaces. It integrates a 3-pole LC (Pi) filter structure with ESD protection in a WDFN-16 package measuring 4.00mm x 1.60mm x 0.79mm. Key electrical parameters include 10 pF capacitance, 20 nH inductance, and 30 dB attenuation within the 800 MHz to 2.7 GHz frequency range. The device operates between -40°C and +85°C.
Feature Summary
- Integrates eight independent channels of EMI filtering and electrostatic discharge protection within a single compact footprint.
- Utilizes a 3-pole LC Pi-filter topology to effectively suppress electromagnetic interference on high-speed data lines.
- Provides robust protection for sensitive interface circuits against transient voltage events.
Applications
- EMI filtering and protection for LCD display interfaces in mobile devices
- Signal conditioning for camera interface data lines
- Protection of control lines in handheld communication equipment
Procurement Notes
Verify the specific suffix DE against the manufacturer's current datasheet to confirm pinout and packaging details. Confirm availability status as distribution listings may vary. Ensure the component meets the required operating temperature range and signal integrity specifications for the target application design.
Selection Notes
Select this component when designing systems requiring multi-channel EMI suppression for parallel data buses such as LCD or camera interfaces. The integrated ESD capability reduces bill-of-materials count compared to discrete solutions. Verify that the 10 pF capacitance value aligns with the impedance matching requirements of the specific transmission lines used in the design.
Part Context
This part belongs to the CM1461 family of EMI filter arrays from onsemi. These components are specifically engineered for portable electronics where space constraints and signal integrity are critical. The family typically offers various channel counts and package options to accommodate different interface densities and form factors.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official distributor databases for cross-reference information if alternative sourcing is required.
