Littelfuse PGB2 0201 Series PULSE-GUARD® ESD Suppressors help protect sensitive electronic equipment against Electrostatic Discharge (ESD). These ESD suppressors feature ultra-low capacitance, low leakage current, and fast response times. The PGB2 0201 ESD suppressors use polymer composite materials to inhibit fast-rising ESD transients while adding virtually no capacitance to the circuit. These PULSE-GUARD ESD suppressors supplement the on-chip protection of integrated circuitry and are well-suited for low-voltage, high-speed applications where low capacitance is necessary. This ensures minimal interference of data signal integrity. Typical applications include antenna circuits, network hardware, HDMI 1.3/1.4/2.0, USB 3.2, computer peripherals, SATA and eSATA, external storage, set-top boxes, and digital cameras.
