HF115F/005-1HS3AF 产品概述

一、概述与主要特性

HF115F/005-1HS3AF 是宏发(HF)出品的一款小型功率继电器,封装为 DIP 形式(外形尺寸 29 × 12.7 mm),适合直接 PCB 安装。该型号为单刀单掷常开(1A NO)触点结构、无极性单线圈驱动,设计用于中低功率电源路的开关控制,兼顾体积紧凑与较高的开关容量,适合家电、工业控制及电源管理等场景。

主要特性:

  • 线圈电压:5 V(无极性,接入时无需考虑极性)
  • 触点形式:一组常开(SPST-NO)
  • 触点容量(电阻负载):16 A @ 250 VAC
  • 最大切换电压:440 V AC / 300 V DC
  • 触点材料:AgSnO2(抗电弧、耐焊接)
  • 封装:DIP,尺寸 29 × 12.7 mm
  • 额定线圈功率:400 mW,线圈电阻 62 Ω(线圈电流约 80 mA)
  • 动作/释放时间:动作 15 ms / 释放 8 ms
  • 工作温度范围:-40 ℃ ~ +85 ℃

二、主要技术参数(要点)

  • 线圈:5 V,62 Ω,额定功率 400 mW;线圈电流约 5 V / 62 Ω ≈ 80.6 mA。
  • 触点容量:最大切换电流 16 A(电阻性负载);对电感性或容性负载需按厂方建议降额。
  • 触点电阻:典型最大值 100 mΩ(新触点);随载流与磨损可能变化。
  • 最大切换电压:交流 440 V,直流 300 V。
  • 响应速度:动作 约 15 ms,释放 约 8 ms。
  • 引脚数:6(包括线圈引脚与触点/支撑引脚,用于 PCB 穿孔安装)。
  • 工作环境:-40 ℃ 至 +85 ℃。

三、电气与热性能注意事项

  • 线圈驱动:5 V 线圈,驱动电流约 80 mA,驱动电路应能提供稳定电流并考虑线圈再生电压(线圈断开时产生反向峰值)。
  • 触点发热:触点电阻最大 0.1 Ω,在 16 A 时理论电压降约 1.6 V,功耗约 25.6 W(P = I^2R)。因此在长期大电流条件下会产生较高热量,应注意散热和降额使用,避免在额定值下持续承载高电流。
  • 负载类型:对电感性(电机、继电器线圈等)或容性(电容器充电)负载,实际可开关电流通常低于电阻性负载额定值,建议采取降额设计或加入保护电路以抑制电弧与过电压。
  • 寿命与可靠性:电气寿命与开关条件密切相关(负载类型、电流、开关频率、抑弧措施等)。具体寿命数据请参照厂方完整资料或样品测试结果。

四、典型应用场景

  • 家用电器电源控制(电磁炉、洗衣机、空调控制板等)
  • 电源管理与线路切换(UPS、开关电源输出切换、电源冗余)
  • 工业控制与继电保护(中低功率负载切换、控制回路)
  • 照明与功率模块(需考虑电容性负载大电流冲击时的保护)

五、安装、焊接与 PCB 布局建议

  • 封装为 DIP 穿孔安装,布局时确保触点与其它热源有足够距离,以利散热。
  • PCB 孔位与尺寸按制造商推荐的封装图纸设计,支撑引脚用于结构稳固,避免长时间震动导致接触不良。
  • 焊接工艺应遵循制造商的温度曲线与时长限制(波峰或回流焊均需注意钢网/焊膏工艺与热冲击),防止对继电器内部材质造成损伤。
  • 对于可能的高电流路径,考虑加粗 PCB 铜箔或使用导线/母排分流,以降低接触处发热与电压降。

六、保护与驱动建议

  • 线圈反向吸收:可使用二极管(直流单向场合)或 RC 抑制器、TVS 器件(若需保持无极性),选型时注意吸收器件对动作释放时间的影响。
  • 触点保护:对高感性或冲击性负载建议使用 RC 吸收、MOV、RC 阻尼、半导体限流或熔断装置,减少电弧损伤与触点磨损。
  • 并联/备用:若需长期承载接近 16 A 的电流,尽量采用并联多个触点或使用专用功率继电器/接触器分担电流。

七、可靠性与选型建议

  • 若实际负载接近或超过额定 16 A,优先选择额定更高、专为连续大电流设计的继电器或接触器。
  • 对于频繁动作或高可靠场合,应咨询厂方电气寿命与机械寿命数据,并在样机上按实际工况进行寿命验证。
  • 选型时综合考虑触点材料(AgSnO2 优于纯 Ag 在抗电弧与抗焊接方面)、封装尺寸、线圈功耗及驱动能力。

总结:HF115F/005-1HS3AF 是一款体积小、线圈功耗低、触点材料抗电弧性能良好的功率继电器,适合中低功率设备的开关控制。选用时应重视对大电流造成的发热与触点磨损风险,并配合合理的保护、降额与散热设计以确保长期可靠运行。若需具体寿命、引脚定义与封装图纸,请索取厂家的完整规格书。

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
