The PGB1010402KR is a polymeric electrostatic discharge (ESD) suppressor manufactured by Littelfuse. Belonging to the PULSE-GUARD® PGB1 series, this device is designed to protect sensitive electronic components and high-speed data interfaces against electrostatic discharge. It features a maximum rated voltage of 12V DC and a typical capacitance of just 0.04pF, making it suitable for low-voltage, high-speed electronic applications.
The PGB1010402KR utilizes advanced polymer composite technology to suppress fast-rising ESD transients while adding virtually no capacitance to the protected circuit. Its ultra-low capacitance helps minimize signal distortion and maintain signal integrity in high-speed data transmission applications.
This component provides ESD protection of up to 8kV contact discharge (typical) and 15kV air discharge (maximum), according to IEC 61000-4-2. It features a typical clamping voltage of 250V and a typical peak voltage of 1000V under the specified 8kV contact discharge test conditions.
The device offers a typical capacitance of 0.04pF measured at 250MHz, an ultra-fast response time of less than 1ns, and typical leakage current below 1nA. These characteristics make it particularly suitable for sensitive electronic circuits where low capacitance and fast transient protection are essential.
The PGB1010402KR provides bidirectional protection for a single signal line. Its compact 0402 (1005 Metric) surface-mount package has nominal dimensions of 0.99 × 0.51 × 0.31mm, making it suitable for space-constrained PCB layouts and automated SMT assembly.
The device supports a minimum of 1,000 ESD pulses and operates across a temperature range of -65°C to +125°C, providing reliable protection under various electronic operating conditions.
The Littelfuse PGB1010402KR is suitable for USB 2.0, IEEE 1394, HDMI, DVI, RF antenna interfaces, digital cameras, external storage devices, set-top boxes, HDTV hardware, computers, and network equipment.
The component is supplied in 7-inch tape-and-reel packaging, with a standard quantity of 10,000 pieces per reel, supporting automated pick-and-place assembly and high-volume electronic manufacturing.
