Product Details

Engineering Features & Specs	Technical & Assembly Advantages	Strategic Business Benefits
30G High-Acceleration Anti-Vibration	Engineered to maintain stable electrical contact under extreme mechanical shocks and 2000Hz frequency.	Zero Signal Dropout: Ensures the BMS monitoring signals remain accurate during high-speed driving or rough terrain, preventing false system alarms.
Phosphor Bronze with Selective Plating	Combines superior electrical conductivity with high fatigue resistance and anti-oxidation properties.	Consistent Low Resistance: Minimizes heat generation at contact points, significantly extending the service life of the battery harness and increasing safety.
15A Continuous / 25A Peak Rating	High power density allows the terminal to handle both steady monitoring signals and intermittent power bursts.	Design Versatility: Allows engineers to use a single terminal type for both signal and low-power lines, simplifying inventory and PCB design.
Cold-Press Crimp Optimization (50-80N)	Optimized geometry for stable mechanical crimping, ensuring a robust bond between wire and terminal.	Production High Yield: Facilitates automated wire processing with consistent pull-out force, reducing rework costs and manufacturing defects.

Q1: Why is the AAUS004-036K03B specifically recommended for BMS?

A: Battery Management Systems require ultra-stable connections to monitor cell voltage and temperature. The AAUS004-036K03B is designed with a 30G vibration resistance rating, ensuring that critical data isn’t lost due to terminal fretting or micro-disconnections caused by road vibration.

Q2: What type of plating does LOTES use for this terminal?

A: It features selective plating on a phosphor bronze base. This strategically applies precious metal (like Gold) to the contact point for maximum conductivity, while using Tin on the crimp area for better weldability/crimping, offering a perfect balance of cost and performance.

Q3: Can this terminal handle 25A peak current safely?

A: Yes. While its continuous rating is 15A, it is engineered to withstand 25A peak surges common during battery balancing or rapid data spikes, provided the wire gauge and housing are correctly matched for heat dissipation.
