Product Details

Product Features	Engineering Advantages	Customer Benefits
Fully Polarized Housing	Engineered with unique chamfered edges to prevent mis-mating even in low-visibility environments.	Foolproof Installation: Eliminates risk of circuit damage caused by reversed polarity, reducing assembly time and ensuring zero-defect production in complex systems.
Positive Latch Lock Mechanism	Features a built-in locking ramp that provides a clear “click” sound and tactile feedback upon mating.	Anti-Vibration Reliability: Ensures the 12-pin connection remains secure under intense vibration or cable pull, preventing intermittent power loss and expensive service calls.
Micro-Fit 3.0 Compact Profile	Delivers up to 8.5A per circuit in a high-density 3.0mm pitch single-row footprint.	PCB Surface Optimization: Allows you to pack significant power delivery into narrow board edge spaces, making it ideal for sleek modern electronics and thin-profile devices.
Fully Isolated Terminals	Individual terminal cavities prevent arcing and short circuits between adjacent contacts.	Enhanced Operational Safety: Provides robust electrical insulation for both power and signal circuits, ensuring your device meets strict international safety standards.

Q1: Which crimp terminals are recommended for the 0436451200 housing?

A: This housing is compatible with Molex 43030 series female terminals. For higher current and reliability, we recommend the 46235 Micro-Fit RMF (Reduced Mating Force) terminals. Please choose the AWG size (typically 20-30 AWG) that fits your wire.

Q2: Is this connector suitable for high-voltage applications?

A: Yes, the Micro-Fit 3.0 series is rated for up to 600V, which is exceptional for its small size. However, always ensure your wire insulation and terminal spacing comply with your specific industry safety standards.

Q3: Can I mate this receptacle with a double-row Micro-Fit header?

A: No. The 43645 series is a single-row housing and will only mate with 43640 series plugs or 43650 series single-row headers. For double-row applications, you would need the 43025 series housings.
