SMN-305是讯普电子(XUNPU)推出的一款翻盖式NanoSIM卡专用卡座,采用SMD表面贴装封装,以超薄结构、便捷操作和宽温适应性为核心优势,精准匹配便携电子设备对紧凑空间与稳定SIM卡连接的需求,是智能手机、智能穿戴等领域的理想连接组件。
SMN-305属于移动通信卡连接领域的小型化专用组件,明确针对当前主流的NanoSIM卡设计,聚焦便携设备的“小空间、易操作、高可靠”连接需求。作为卡座类产品,其集成了SIM卡固定、触点接触、结构防护等完整功能,无需额外搭配其他连接配件,可直接集成到终端设备主板中,简化设计流程。
SMN-305采用翻盖式连接方式,这是其最核心的操作优势:无需借助工具,通过手动开合翻盖即可快速完成NanoSIM卡的插入、取出与固定;翻盖闭合后能有效锁定卡片,避免设备移动过程中SIM卡松动导致的信号中断,同时翻盖结构可减少卡片与外部环境的直接接触,提升防尘、防刮性能。
产品严格匹配NanoSIM卡的物理尺寸与触点布局,确保卡片插入后触点与卡座内部的导电触点精准对齐,接触电阻稳定,信号传输无损耗。NanoSIM卡是当前智能手机、平板等设备的标准配置,SMN-305的适配性覆盖了90%以上的主流便携终端。
SMN-305的本体最大高度仅1.4mm,是同类产品中的超薄级别。这一参数直接解决了超薄终端(如5mm以下厚度的智能手机、智能手表)内部空间紧张的问题——无需牺牲其他组件的布局,即可集成稳定的SIM卡连接功能,助力设备实现“轻薄化”设计目标。
产品支持**-25℃至+85℃的宽温度范围**,满足不同地域、不同使用场景的需求:在北方冬季户外使用时,低温不会导致卡座材料脆化或触点接触不良;在夏季高温环境(如车内、户外暴晒)下,也能保持稳定的连接性能,避免因温度变化导致的SIM卡识别异常。
SMN-305采用SMD(表面贴装器件)封装,具有两大生产优势:
作为讯普电子(XUNPU)的核心连接器产品之一,SMN-305遵循行业标准(如IEC 60950等安全规范)进行设计与生产,关键触点采用耐磨导电材料,确保插拔寿命(通常可达1000次以上,满足日常使用需求);产品出厂前经过严格的高低温测试、振动测试与接触可靠性测试,可有效避免因连接不良导致的设备故障。
SMN-305的特性使其广泛适配以下场景:
综上,SMN-305以“超薄、便捷、可靠”为核心竞争力,精准匹配便携电子设备的发展趋势,是终端厂商优化SIM卡连接方案的优质选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
