HFD27/005-S 是宏发(HF)推出的一款小型低功耗通用继电器,封装为 8 引脚 DIP(尺寸:20.2 × 10.2 mm),触点形式为两组转换(2C,双刀双掷)。该继电器以 5V 线圈驱动、额定线圈功率仅 200 mW 为特点,适合在空间受限且需低功耗切换控制的场合使用。
若设计要求低功耗、小体积并需要 DPDT 功能,HFD27/005-S 是一个性价比高的选择;但当系统需切换更高电流或频繁切换感性负载时,应考虑更高额定触点或增加外部保护电路。选型时请结合预期负载类型、开关频率与环境条件,必要时联系供应商获取完整规格书与耐久性数据。
如需封装引脚图、典型接线示例或替代型号建议,我可以继续提供详细信息。

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.
