DF40C-40DS-0.4V(51)是日本广濑电机(HRS)推出的0.4mm间距高密度板对板连接器,专为紧凑型电子设备的内部信号与小功率传输设计,凭借双排40针垂直立贴结构、金镀层触头及宽温适应性,在有限空间内实现稳定可靠的电气连接,是消费电子、工业控制等领域的优选方案。
0.4mm引脚间距大幅压缩连接器体积,双排40针设计仅占用约10mm×2.5mm的PCB面积,满足智能手机、智能穿戴等对空间极致压缩的设备需求,是小型化产品的核心连接组件。
垂直立贴安装方式使连接器垂直于PCB表面,相比卧式贴装减少30%以上横向占用空间,尤其适合多层PCB堆叠、模块紧凑布局的场景(如TWS耳机充电盒内部)。
采用嵌入式槽型对接结构,插头与插座触头精准配合,避免插拨时横向偏移,降低触头磨损风险;同时槽型设计具备防误插功能(方向对准后才能插入),减少生产失误。
触头表面镀0.2~0.3μm厚纯金,具有:
工作温度覆盖-35℃至+85℃,满足工业控制(如低温车间)、车载电子(如高温座舱)等场景的温度变化需求,无需额外防护即可稳定运行。
单触头300mA额定电流满足大多数小功率信号(如SPI、I2C)与电源传输需求,金镀层触头的低电阻特性可支持高速数字信号传输(如100Mbps以上)。
SMD封装适合自动化贴装(回流焊工艺),可与其他SMD元件同步生产,贴装精度要求为±0.1mm,与主流贴片机兼容,提升工厂生产效率。
与HRS DF40C系列同规格插头(如DF40C-40P-0.4V)完全兼容,对接精度高,避免因连接器不匹配导致的连接故障。
总结:DF40C-40DS-0.4V(51)凭借高密度、小尺寸、高可靠性的特点,成为紧凑型电子设备内部连接的核心组件,尤其适合对空间与性能平衡要求较高的消费电子、工业控制等领域。
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.
