HF3FF/005-1HST 产品概述
一、产品简介
HF3FF/005-1HST 是宏发（HF）公司推出的一款超小型大功率功率继电器，采用插件封装（尺寸约19×15.2mm），单刀单掷常开（SPST-NO）触点结构，适用于对体积有严格要求但需要较大开关容量的电子与电力控制应用。
二、主要电气参数
- 线圈电压：5V DC（无极性单线圈）
- 线圈电阻：70Ω，线圈电流约为71mA（5V/70Ω），额定线圈功率约360mW
- 触点形式：一组常开（单刀单掷-常开）
- 触点材料：AgSnO2（抗电弧、耐电擦伤）
- 触点容量（电阻负载）：10A @ 28VDC；10A @ 277VAC
- 最大切换电流：15A
- 最大切换电压：28VDC；277VAC
- 接触电阻：≤100mΩ
- 动作/释放时间：动作约10ms，释放约5ms
- 引脚数：4（插件形式）
- 工作温度：-40℃ ~ +85℃
三、产品特点
- 小体积大功率：19×15.2mm 套件下仍能提供10A 等级的开关能力，便于高密度设计。
- 低功耗线圈：360mW 额定功耗，驱动电流小，适合微控制器或低功耗驱动电路。
- 无极性线圈：线圈对极性不敏感，布线更方便。
- 优良触点材料：AgSnO2 提升耐电弧性与开关寿命，适合频繁开关场合。
- 快速响应：动作/释放时间短，有利于精确控制与保护电路设计。
四、典型应用场景
- 工业控制与PLC 输出扩展模块
- 家用电器与厨房电器的电源切换
- 安防与楼宇控制系统
- 通讯设备的电源管理与负载切换（在额定条件下使用）
- 电池管理与DC-DC 控制回路（注意电弧与抑制措施）
五、驱动与抑制建议
- 驱动电流约71mA，直接由MCU 的驱动端口可能不足，建议用晶体管或驱动芯片驱动并带限流保护。
- 线圈为无极性，但若使用有开关器件（如NPN、MOSFET）控制线圈，仍建议在驱动器两端并联二极管、TVS 或RC 抑制网络以降低反向电压与抑制干扰，选择抑制元件时需兼顾动作/释放时间要求。
- 对于高电流切换（接近10A）建议在负载端加装适当的浪涌吸收或灭弧装置（如RC、SIRA、电感等），以延长触点寿命。
六、安装与注意事项
- 插件封装，焊接和安装时请参考宏发的官方数据手册，遵循推荐的焊接温度曲线与机械应力限制。
- 在高温、高湿或强振环境中使用前，请验证实际应用的可靠性与寿命数据（按厂家寿命试验为准）。
- 对于安全关键或长寿命要求的系统，建议在设计阶段进行整机级的EMC 与热分析，合理安排散热与隔离。

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.
