EMI filter for space-sensitive designs

24 November 2021 Circuit & System Protection

Engineered as a dual-channel filter array, the VEMI256A-SD2 two-channel EMI filter from Vishay Intertechnology 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.

The VEMI256A-SD2 is a highly integrated two-channel filter in an ultra-compact chip level package ideal for space-constrained applications. It 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. The clamping voltage is rated at ±30 kV and helps prevent damage to the protected device when subjected to ESD pulses. The VEMI256A-SD2 has been tested per IEC 61000-4-2 standards, meeting ESD immunity requirements with ratings of ±25 kV for both contact and air discharge. The filter also features a typical cut-off frequency of 60 MHz, line resistance of 60 Ω and an operating temperature of ‑40°C to +150°C.

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

The VEMI256A-SD2 is well suited for a variety of mobile and wired communication devices, including smartphones, tablets, portable electronic devices, display interfaces, keypads and high-speed I/O data ports.
