HF49FD/005-1H12T 产品概述
一、产品简介
HF49FD/005-1H12T 是宏发（HF）推出的一款微型功率继电器（Miniature Power），封装为 SIP（20 × 5 mm），体积小、功耗低、驱动电流小，适合对空间和能耗有严格要求的电路。线圈额定电压为 5V，额定线圈功率 120 mW（线圈电阻 208 Ω），为无极性单线圈设计，方便微控制器直接或经驱动器件控制。
二、主要电气参数
- 线圈电压：5 V
- 线圈电阻：208 Ω（线圈电流约 24 mA）
- 额定线圈功率：120 mW
- 触点形式：一组常开（单刀单掷，SPST-NO）
- 触点材料：AgSnO2
- 触点容量（电阻负载）：5 A @ 30 VDC；5 A @ 250 VAC
- 最大切换电压：250 V AC / 30 V DC
- 最大切换电流：5 A
- 接触电阻：≤100 mΩ
- 动作时间：约 10 ms；释放时间：约 5 ms
三、机械与环境特性
- 引脚数：4（适用于通孔 PCB 安装）
- 封装尺寸：20 × 5 mm（SIP）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 描述：Miniature Power，适合紧凑型电源管理和信号隔离应用
四、应用场景
- 通信设备、仪表仪器中的电源或信号切换
- 工业控制与自动化的小电流控制回路
- 家用电器、安防系统的控制板
- 需要低驱动电流、节能且占板面积小的场合
五、使用建议与注意事项
- 线圈驱动：线圈为无极性，直流驱动时建议在驱动晶体管两端并联续流二极管或用 RC 抑制，保护驱动器件。线圈电流约 24 mA，可直接由 MCU 的 I/O 或通过小型驱动器驱动，但推荐使用驱动管以提高可靠性。
- 负载特性：标称 5 A 为电阻性负载条件下的能力；对于感性或电感性负载（直流电机、继电器线圈等），开关产生的电弧会加速触点损耗，建议采取熄弧措施（RC 吸收、TVS、机械隔离或使用外部接触器/固态器件）。
- 寿命与降额：为延长触点寿命，建议在实际应用中对标准额定值进行适当降额，尤其是直流大电流场合；关注制造商的寿命曲线以匹配使用频率。
- 布局与焊接：SIP 四脚通孔安装，焊接时注意温度和时间，以免损伤封装或影响线圈特性。
六、优势总结
- 体积小、SIP 封装适合高密度 PCB 布局
- 低线圈功耗（120 mW），驱动电流小（约 24 mA），有利于节能设计
- 触点材料为 AgSnO2，具有较好的开关耐久性和抗烧蚀能力
- 适用电压范围广（最高 250 VAC / 30 VDC），适配多种交流/直流场景

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
