HF49FD/024-1H12 是宏发(HF)出品的一款小型电源继电器,线圈额定电压为 24VDC,触点形式为一组常开(SPST-NO)。该继电器体积紧凑(约 20×5×12.5 mm)、功耗低、响应快,适合需要隔离开关且空间受限的低功率控制场合。
该型号为小型 SIP 贯穿式封装,便于印制板(PCB)安装与波峰焊(或手工焊接)。4 引脚设计通常包括两脚线圈、两脚触点(具体引脚排列请参照官方封装图)。无极性线圈简化了接线,但若采用单向抑制器(如二极管)需注意极性。
HF49FD/024-1H12 以其小体积、低线圈功耗和 5A 切换能力,适合对空间、能耗有严格要求的控制系统。在实际设计与采购前,建议下载并仔细阅读宏发官方数据手册,确认封装图、引脚排列、电寿命与环境测试数据,或联系供应商获取样品和相关测试报告以完成最终设计验证。

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.
