液晶显示器和照相机的EMI滤波器阵列与ESD保护 LCD and Camera EMI Filter Array with ESD Protection
Product Description
The CM1452 family of pi-style EMI filter arrays with ESD protection, integrates four, six and eight filters C-L-C in CSP form factor with 0.40mm pitch. Each EMI filter channel of the CM1452 is implemented as a 3-pole L-C filter where the component values are 20pF-17nH-20pF. The CM1452 roll-off frequency at - 6dB attenuation is 330MHz and can be used in applications where the data rates are as high as 132Mbps and provide greater than 30dB over the 800MHz to 2.7GHz frequency range.
Features
• Four, six and eight channels of EMI filtering with integrated ESD protection
• ±15kV ESD protection on each channel IEC 61000-4-2 Level 4, contact discharge
• ±30kV ESD protection on each channel HBM
• Greater than 30dB attenuation typical at 1 GHz
• Chip Scale Package CSP with 0.40mm pitch and 0.25mm CSP solder ball which features extremely low parasitic inductance for optimum filter and ESD performance
• OptiGuardTM Coating for improved reliability at assembly
• RoHS-compliant, lead-free finishing
