Product Description

This pre-crimped finished wire-to-board assembly uses complete original JST AUH series matched components, all parameters cross-verified from JST official global datasheet and authorized distributor data:

Female Receptacle Housing PN: AUHR-03V-S, 3-circuit single-row crimp socket, 1.20mm center pitch, gray PA66 flame retardant plastic
Dedicated Crimp Terminal: AUH series tin-plated / gold-plated phosphor bronze crimp contact, exclusive for AWG28~AWG32 ultra-fine stranded wire
Mating SMT PCB Header: BM03B-AUHKS-GA-TB vertical surface mount male wafer for PCB reflow soldering
Matching Wire Spec: AWG28/AWG30 flexible thin electronic wire, insulation outer diameter φ0.40~φ0.63mm

The connector adopts space-saving flat layout: vertical top-entry mating with horizontal parallel wire outlet, wires extend flat against PCB surface without vertical bending dead angles, perfectly fit ultra-narrow internal battery cavity of slim notebooks and smart home control panels. The integrated friction lock buckle firmly locks mated PCB header to avoid accidental disconnection caused by equipment vibration and wire pulling force during battery charging & discharging cycles. Molded polarization guide ribs physically block reverse plugging, eliminating PCB short-circuit and chip burnout risks during mass assembly production.

Dual-point elastic crimp terminals maintain ultra-low initial contact resistance ≤10mΩ, stable power and temperature detection signal transmission without voltage drop for lithium battery charge-discharge loop. Multi-color coded thin wires distinguish power positive, power negative and thermistor signal circuits, simplifying circuit sorting during battery module assembly.

Every finished harness undergoes 100% strict quality inspection before shipment, including continuity test, terminal pull retention force test, 500V AC high voltage withstand test and thermal cycling aging test. We supply single-end AUHR finished cables and cross-type dual-connector conversion harness OEM mass customization solutions for notebook battery manufacturers, smart home appliance and wearable electronics factories.

Advantages

Ultra-compact low-profile 1.2mm fine pitch design: Only 1.85mm mated stacking height + horizontal flat wire outlet layout, drastically save limited internal battery space of slim notebooks, smart home mini appliances and wearable devices, realize thinner battery structural design.
Integrated friction self-locking anti-drop structure: After full mating, the lock buckle produces obvious clamping feedback, effectively prevent loose contact faults caused by long-term vibration during battery charge-discharge cycles.
Physical anti-reverse polarization protection: Molded positioning ribs completely block reverse insertion, reduce mass production short-circuit defective rate and lower manufacturer after-sales maintenance cost of battery modules.
Stable 2A load capacity in tiny package: Balances ultra-small size and lithium battery power supply demand, simultaneously transmit main power loop and battery temperature detection signal in one 3Pin harness.
High elasticity dual-point crimp terminals: Phosphor bronze base with optional gold plating for anti-oxidation, maintain stable low contact resistance after repeated temperature cycling, avoid battery charging abnormal disconnection.
Flexible full OEM customization support: Arbitrary adjustable cable length, wire thickness and wire color sequence according to lithium battery module circuit schematics; small prototype sample orders available for product development verification.
