A1257: 1.25mm Pitch High Current Wire to Board Connector
Product Features
The A1257 series is a high-density wire-to-board connector specifically designed for consumer electronics and compact smart devices. Featuring ultra-narrow pitch design, high stability, flame-retardant materials, and SMT compatibility, the series focuses on improving space utilization and connection reliability in miniaturized applications while providing a cost-effective interconnection solution.
Ultra-narrow Pitch Design
The standardized 1.25 mm pitch is compatible with PCB mounting and supports 6P, 12P, and 20P configurations, effectively saving board space and meeting the requirements of high-density circuit designs.
Excellent Electrical Performance
Contact resistance ≤20 mΩ, insulation resistance ≥100 MΩ, dielectric withstand voltage of 500 V AC for 1 minute, and a rated current of 1.0 A (AC/DC), satisfying low-power signal and power transmission requirements.
High-quality Materials and Manufacturing
The housing is made of LCP UL94 V-0 flame-retardant plastic, offering excellent heat resistance during reflow soldering. The terminals use a brass base material with tin plating, while the solder pads are made of brass with matte tin plating, enhancing electrical conductivity, oxidation resistance, and wear resistance.
Strong Assembly Adaptability
Fully compatible with SMT automated placement processes, the connector features an integrated anti-misinsertion guide design and supports customized pin-count configurations, effectively reducing assembly error rates.
