What is Micro-Fit Connector?

The Molex Micro-Fit 3.0 Connector System is a high-performance connector designed to meet the demands of both power and signal connections in various applications. With a compact 3mm (0.118″) pitch, it provides a high-density solution without compromising on performance, capable of handling currents up to 8.5A. The versatility of the Micro-Fit 3.0 system makes it a preferred choice for many industries, offering both single- and dual-row configurations in a wide range of circuit sizes from 2 to 24.

Key Features of the Micro-Fit 3.0 Connector

1. Positive Latching
   The Micro-Fit 3.0 features a positive latch mechanism that ensures a secure, reliable connection. This latch minimizes the chances of accidental disconnections during operation, which is essential for ensuring the continuity and integrity of electrical systems.

2. Fully Polarized Housings
   The housings are designed to be fully polarized, preventing incorrect mating between connectors. This ensures that connectors are always installed correctly, reducing the risk of faults or operational failures.

3. Isolated Terminals
   Each terminal in the Micro-Fit 3.0 is fully isolated, offering protection against potential damage during handling and mating. This makes the connectors more durable and robust, improving their lifespan and reducing the need for maintenance.

4. High-Temperature Resistance
   The Micro-Fit 3.0 connectors are engineered with high-temperature LCP (Liquid Crystal Polymer) headers, which are capable of withstanding up to 260°C during IR reflow processes. This makes them ideal for use in environments where temperature control is critical, such as in electronic assembly.

5. Flexible Terminals
   With a range of terminal options from 30AWG to 18AWG, the Micro-Fit 3.0 offers significant design flexibility, allowing it to be used in various types of applications, from small, low-power devices to larger, higher-power systems.

6. Multiple Mounting Options
   The connectors are available in SMT (Surface-Mount Technology), press-fit, and surface-mount versions, making them adaptable to different manufacturing processes and designs. Fitting nails and solderable clips can be used for header retention and strain relief, enhancing mechanical stability.

7. Optional Terminal Position Assurance (TPA)
   The optional TPA feature reduces the likelihood of assembly errors by preventing terminal back-outs. This helps to ensure the correct positioning of terminals during the assembly process and contributes to a more reliable end product.
