CM1430-04DE

Overview

The CM1430-04DE is a four-channel EMI filter array with integrated ESD protection, manufactured by onsemi. It utilizes a Pi-style RC (C-R-C) circuit topology to suppress electromagnetic interference in data lines. The component features a capacitance of 15 pF and resistance of 120 Ohms per channel, providing an attenuation of 30 dB within the frequency range of 800 MHz to 6 GHz. It operates within a temperature range of -40°C to +85°C and is housed in an 8-lead WDFN package measuring 1.75 mm x 1.4 mm x 0.8 mm.

Feature Summary

• Integrates four independent RC filter channels with ESD protection in a compact surface-mount package
• Provides high attenuation for electromagnetic interference suppression across wideband frequencies
• Designed for low capacitance to maintain signal integrity in high-speed data applications

Applications

• EMI filtering for LCD display interfaces
• Signal line protection for camera modules
• High-speed data bus noise suppression

Procurement Notes

Verify current availability status as the part may be discontinued or subject to supply constraints. Confirm package orientation and pinout compatibility during design-in. Ensure static-safe handling procedures are followed due to the integrated ESD protection capabilities. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring simultaneous EMI filtering and electrostatic discharge protection for multiple data lines. The low parasitic capacitance makes it suitable for high-speed interfaces where signal distortion must be minimized. Evaluate thermal performance within the specified operating temperature range to ensure reliability in enclosed electronic assemblies.

Part Context

This device belongs to the CM1430 family of EMI filter arrays from onsemi, which offers various channel configurations including six and eight filters. These components are specifically engineered for portable electronics and consumer devices where space constraints and signal integrity are critical design factors. The family provides standardized solutions for protecting sensitive input/output ports from environmental noise and electrical stress.

Replacement Considerations

Check for direct substitutes within the CM1430 series or compatible RC filter arrays from other manufacturers. Verify that alternative components match the 15 pF capacitance and 120 Ohm resistance values to maintain identical filtering characteristics. Ensure physical footprint compatibility with the WDFN-8 package dimensions.
