HF115F/024-2ZS4AF 产品概述
一、产品简介
HF115F/024-2ZS4AF 为宏发（HF）出品的小型功率继电器，双刀双掷（2C/DPDT）触点结构，适合电路中对中等功率交流或直流负载的切换控制。封装为标准DIP，外形尺寸紧凑（29×12.7×15.7 mm），便于PCB安装与批量生产应用。
二、主要参数
- 触点形式：两组转换（2C，双刀双掷）
- 额定线圈电压/功耗：24 VDC / 400 mW
- 线圈电阻：1.44 kΩ（工作电流≈16.7 mA）
- 触点容量（电阻负载）：8 A @ 250 VAC
- 最大切换电流：8 A（持续），最大切换电压：440 V AC / 300 V DC
- 触点电阻：≤100 mΩ
- 触点材料：AgSnO2（氧化锡银合金）
- 动作/释放时间：约 15 ms / 8 ms
- 工作温度范围：-40 ℃ ～ +85 ℃
- 引脚数：8，封装形式：DIP
三、产品特点
- 小体积、高密度封装，适合空间受限的控制板设计。
- AgSnO2 触点材料抗电弧与抗焊接性好，适合频繁开关和含感性负载场景。
- 线圈功耗低（400 mW），工作电流小（≈16.7 mA），利于低功耗系统设计与并联驱动。
- 无极性线圈设计，接线方便；在采用抑制元件（如二极管）时需注意极性影响。
四、典型应用
- 家电控制（洗衣机、微波、空调控制板）
- 工业控制与自动化（继电控制、信号切换）
- 照明与安防设备（照明分路、报警系统）
- 通信与测试设备的小电流开关应用
五、使用建议与注意事项
- 虽然额定切换电流为 8 A，但电机启动、电容充电或白炽灯等会产生显著浪涌电流，应评估瞬时应力并必要时选用吸收器或接触器。
- 对于感性负载，建议在继电器触点或线圈端使用 RC 抑制、TVS 或 MOV，以减少电弧与干扰。注意：若在线圈上并联二极管，线圈将变为有极性，安装时需保证极性正确。
- 为保证可靠寿命，应遵循制造商推荐的焊接温度曲线与清洗工艺，避免高温长时曝晒或化学腐蚀环境。
- 设计 PCB 布局时考虑足够的爬电距离与触点间距，满足高压需求。
六、封装与采购信息
- 尺寸：29 × 12.7 × 15.7 mm，DIP 引脚 8 脚，便于 wave/solder 与自动贴装后回流焊工艺配合。
- 品牌：HF（宏发），型号：HF115F/024-2ZS4AF。订购时请确认完整型号与包装形式以保证一致性。
总结：HF115F/024-2ZS4AF 是一款体积小、线圈功耗低、触点容量适中的通用型功率继电器，适合中小功率开关应用。在使用时应关注浪涌电流与抑制保护以确保长期可靠运行。

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.
