SP0402B-ULC-01ETG

SP0402B-ULC-01ETG is a vendor-specific part number for a 0402-sized SMD component. The SP0402B family covers small, surface-mount devices, and the “ULC” suffix typically indicates an Ultra-Low Capacitance or variant within that family, while “01ETG” encodes the particular packaging/lot variant defined by the manufacturer. To introduce it properly you need the manufacturer’s datasheet, which will confirm the device type (e.g., resistor, capacitor, diode/ESD protector), electrical ratings (voltage, capacitance if applicable, leakage/current), footprint/land pattern, packaging details, and typical applications.
If you can provide the vendor name or a datasheet link, I can give a concise summary of its function, key specs, and recommended usage.

- Pin count: 2 pins (two-terminal device).
- Function: Ultra-low-capacitance transient-voltage-suppressor/ESD protection diode (ESD protection) in a 0402 package, used to protect high-speed signal lines from ESD and transient overvoltage.

SP0402B-ULC-01ETG is an ultra-low capacitance ESD protection diode array (0402 package). Typical application areas:
- Protect high-speed data lines from ESD and transient surges without degrading signal integrity
- Interfaces: USB 2.0/3.0, HDMI, DisplayPort, MIPI (CSI/DSI), LVDS, PCIe, Ethernet, and other differential/high-speed nets
- Board-level protection near connectors and flex cables in mobile devices, laptops, cameras, wearables, and IoT
- Automotive and industrial electronics requiring ESD protection on data lines while preserving high-speed performance

Package type: Surface-mount device (SMD) in a 0402-size chip package (1.0 × 0.5 mm).
