CM1453-04CP

• 4 channels of EMI filtering
• ±15kV ESD protection (IEC 61000-4-2, contact discharge)
• ±30kV ESD protection (HBM)
• Greater than -40dB of attenuation at 1GHz
• 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
• OptiGuard™ Coating for improved reliability at assembly
• RoHS compliant

The CM1453-04CP is a pi-style EMI filter array with ESD protection, which integrates four filters (C-L-C) in CSP form factor with 0.40mm pitch. Each EMI filter channel of the CM1453-04CP is implemented as a 3-pole L-C filter where the component values are 9.5pF-20nH-9.5pF. The roll-off frequency at -6dB attenuation is 380MHz and can be used in applications where the data rates are as high as 160Mbps while providing greater than -35dB over the 800MHz to 2.7GHz frequency range. The parts include ESD diodes on every I/O pin, that provide a high level of protection against electrostatic discharge (ESD). The ESD protection diodes connected to the filter ports are designed and characterized to 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.

CM1453-04CP is particularly well suited for wireless handsets, mobile LCD modules and PDAs because of its small package format and easy-to-use pin assignments. In particular, the CM1453-04CP is ideal for EMI filtering and protecting data and control lines for the LCD display and camera interface in mobile handsets.

The CM1453-04CP incorporates OptiGuard™ which results in improved reliability at assembly. It is manufactured with a 0.40mm pitch and 0.25mm CSP solder ball to provide up to 28% board space savings vs. competing CSP devices with 0.50mm pitch and 0.30mm CSP solder ball.
