The Micro-Fit 3.0 connector system is designed to deliver a reliable, high-performance solution for power applications where space is at a premium. Featuring a compact 3.00mm pitch, this family of products offers superior current capability in a small footprint, making it ideal for a wide range of industries including consumer electronics, appliances, business equipment, and industrial controls.

Key Features & Benefits:

3.00mm Pitch: Saves valuable PCB space compared to larger traditional power connectors.

High Current Rating: Capable of handling up to 5.0 A per circuit, providing robust power delivery.

TPA and CPA Members: Features independent Terminal Position Assurance and Connector Position Assurance latches. These secondary locks ensure terminals are fully seated and prevent mating connectors from unintentionally separating, enhancing overall reliability.

Fully Polarized Housings: Prevents mis-mating during assembly, ensuring correct connection every time.

Robust Design: The connector housings are constructed to withstand automated mating processes and provide long-term durability.

SMT & THT Options: Available in both Surface-Mount and Through-Hole Termination styles, offering design flexibility for different PCB layouts and manufacturing processes.

Forked (Dual-Finger) Terminal Design: Provides a stable, gas-tight connection and improves retention in the housing.

Applications:

Consumer Electronics: Smart speakers, gaming consoles, set-top boxes.

Home Appliances: White goods, power tools, vacuum robots.

Computer & Business Equipment: Printers, copiers, monitors, PC peripherals.

Industrial Controls: PLCs, sensors, motor drives.

Telecommunications: Network equipment, power supplies.
