CG0603MLC-3.3LE Description

Short technical summary and product information.

The Bourns CG0603MLC-3.3LE is a monolithic ESD protection device from the ChipGuard MLC series, designed to safeguard sensitive electronics from electrostatic discharge events. It is housed in a compact 0603 (1608 metric) surface-mount package and uses multilayer ceramic varistor (MLCV) technology. The part provides bidirectional ESD clamping with a typical response time of less than 1 nanosecond.

Key electrical characteristics include a maximum DC working voltage of 3.3 V, very low leakage current below 0.01 µA, and an extremely low typical capacitance of 0.2 pF at 1 MHz, making it suitable for high-speed signal lines such as USB 3.0, camera links, and antenna ports. The device meets IEC 61000-4-2 Level 4 ESD requirements with ±8 kV contact and ±15 kV air discharge withstand, and it can endure 1000 typical ESD pulses (8 kV contact) without failure.

The operating temperature range is specified as -40 °C to +85 °C (per existing database) while the series datasheet indicates -55 °C to +125 °C. The part is listed as AEC-Q200 compliant and is marked with a California Proposition 65 warning. Available packaging options include tape and reel, cut tape, and Digi-Reel through distribution.
