DF52-4S-0.8H(21)是日本HRS(广濑电机)推出的高密度微型线对板卧贴针座,属于HRS DF系列连接器产品线,专为小型化、高密度电子设备的内部信号/电源连接设计。HRS作为全球连接器领域的技术领先品牌,以精密工艺、高可靠性著称,该产品延续了品牌在微型连接器领域的技术积累,满足消费电子、工业、车载等多场景的紧凑布局需求。
针座插针采用镀金表面处理(厚度≥0.3μm),减少氧化、降低接触电阻(≤20mΩ),保证信号传输稳定性;接触力设计为0.5~1.0N/针,适配HRS DF系列线端连接器(如DF52-4P-0.8C),插拔时接触紧密,避免振动导致松动。
SMD封装兼容标准回流焊工艺(峰值温度≤260℃,时间≤10秒),适合自动化贴装生产线,生产效率提升30%以上;引脚设计符合IPC-A-610标准,焊接后焊点可靠性强,虚焊率≤0.1%。
采用表面贴装(卧贴),需将针座贴装于PCB指定焊盘位置,通过回流焊完成焊接;安装时需注意PCB焊盘布局与针座引脚精准匹配(间距0.8mm±0.05mm),避免错位。
需搭配HRS DF系列线端连接器使用(如DF52-4P-0.8C、DF52-4P-0.8C(51)),确保线端与针座的插针/插孔精准对接;不建议搭配非HRS原厂线端,避免接触不良或机械干涉(插拔寿命缩短50%以上)。
DF52-4S-0.8H(21)因紧凑尺寸、高可靠性,广泛应用于以下场景:
DF52-4S-0.8H(21)是HRS针对高密度小型化设备设计的高可靠卧贴针座,参数适配多场景需求,工艺成熟稳定,是电子设备内部连接的优质选择,尤其适合对尺寸、可靠性要求严格的终端产品。

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.
