Two-channel filter suppresses EMI and RFI

Engineered as a dual-channel filter array, the VEMI256A-SD2 helps suppress electromagnetic interference (EMI) and radio frequency interference (RFI) for two protection paths while providing robust system-level electrostatic discharge (ESD) protection for interface line filtering.

This EMI filter is a highly integrated two-channel filter in an ultra-compact chip level package ideal for space-constrained applications.

The device offers a low leakage current for ESD protection and enables designers to filter and clamp two different signal or data lines to the device’s ground.

Clamping voltage is rated at ±30 kV and helps prevent damage to the protected device when subjected to ESD pulses.

Tested per IEC 61000-4-2 standards, the filter meets ESD immunity requirements with ratings at ±25 kV for both contact and air discharge.

It also features a cut-off frequency of 60 MHz (typical), a line resistance of 60Ω (typical), and an operating temperature of ‑40°C to +150°C.

The VEMI256A-SD2 filter is available from Mouser Electronics in a 0.45 mg, CLP1007-5M package that prevents device shorts while offering optimum stand-off and minimal tilt and rotation for space-sensitive devices.

The filter also meets the UL 94 flammability standard and has a moisture sensitivity level classified to level 1 according to J-STD-020.

Applications include mobile and wired communication devices, including smartphones, tablets, portable electronic devices, display interfaces, keypads, and high-speed I/O data ports.
