CM1624-08DE EMI filter
The CM1624-08DE is a compact, integrated 8-channel RLC EMI filter with integrated ESD protection from onsemi, specifically optimized for T-Flash/MicroSD interfaces in mobile phones, wearables, and other battery-powered portable electronic devices. It integrates a 3rd-order low-pass filter network with 40Ω series termination resistors, 25kΩ pull-up resistors, and TVS diodes on all signal lines, fully complying with SD and SPI mode specifications to streamline interface design and reduce external BOM components. Built with RLC values of 40Ω, 12pF, and 20nH, it features a 300MHz cutoff frequency to suppress high-frequency EMI/RFI noise while maintaining signal integrity for high-speed data transmission. The integrated TVS diodes deliver robust ESD protection up to 15kV contact discharge per IEC 61000-4-2 Level 4, safeguarding sensitive circuitry from electrostatic damage.
Housed in a miniature 16-UFDFN package measuring 3.3×1.35×0.5mm with a 0.4mm lead pitch, it offers a small footprint for space-constrained PCB layouts and supports surface-mount assembly. Operating within a -40°C to 85°C temperature range and rated for 2.5V to 5V supply voltage, it ensures stable performance across diverse portable device operating conditions. This device also includes an additional TVS diode for Vcc bus protection, enhancing system-level reliability for memory card interfaces. Though now obsolete, it remains a proven solution for legacy portable designs requiring EMI filtering, ESD protection, and line termination in a single compact package.
