HF115F/005-1ZS3 产品概述

HF115F/005-1ZS3 是宏发(HF)推出的一款小型功率通用继电器,采用 DIP 封装(尺寸约 29 × 12.7 mm),为一组转换触点(1C,单刀双掷 SPDT)设计。该继电器适合需要较大载流能力但占板面积受限的场合,具有 16A 的较高开关电流能力与 5V 无极性线圈驱动特性,常用于家电、工业控制、照明与电源保护等领域。

一、主要技术参数(关键规范)

  • 触点形式:一组转换(1C,SPDT)
  • 额定线圈电压:5V DC(无极性单线圈,可任意接线极性)
  • 线圈功率:约 400 mW(典型)
  • 线圈电阻:62 Ω(5V 下线圈电流约 5V/62Ω ≈ 80.6 mA)
  • 触点材料:AgCdO(氧化银-镉)
  • 触点电阻:典型 100 mΩ
  • 最大切换电流:16 A
  • 触点容量(电阻负载):16 A @ 250 VAC
  • 最大切换电压:440 V(AC)、300 V(DC)
  • 动作时间:约 15 ms;释放时间:约 8 ms
  • 工作温度范围:-40 ℃ 至 +85 ℃
  • 引脚数:8 针(DIP 封装)
  • 封装尺寸:DIP,约 29 × 12.7 mm

二、产品特性与优势

  • 高电流能力:单触点可切换最大 16A,适合常见家电与功率负载的交流或直流开关控制。
  • 无极性线圈:5V 线圈为无极性设计,接线更方便,适合自动化安装和替换。
  • 紧凑封装:DIP 封装占板面积小,便于标准 PCB 插装与波峰/回流焊工艺(请参考制造商的焊接曲线)。
  • 良好触点性能:AgCdO 触点在抗电弧与耐擦伤方面有较好表现,适合频繁切换的场合(注意环境与法规要求)。
  • 宽温度范围:-40℃ 至 +85℃,可满足多数工业与民用环境的工作需求。

三、典型应用场景

  • 家用与商用电器(洗衣机、微波炉、空气净化器、热水器等)
  • 工业控制系统(继电控制、PLC 外围驱动)
  • 照明与配电开关(交流负载切换)
  • 开关电源与逆变器的辅助继电器(注意与高压直流配合时的保护)
  • 安防与自动化设备中的电路切换

四、使用与设计注意事项

  • 负载类型:16A 为电阻性负载下的额定值,开关感性负载(电机、继电器线圈、变压器)时应适当降额,并加装吸收元件(RC、TVS、MOV 或气隙/磁吹)以抑制电弧与抑制过压。
  • 直流开关注意:直流 300V 的开关能力在实际中对灭弧要求更高,特别是高电流直流场合需更严格的保护与较大安全裕度。
  • 触点材料与法规:AgCdO 有较好电弧耐受性,但含镉,可能在某些地区或应用中受限(如 RoHS 等环保要求),选型时需确认合规性。
  • 线圈驱动:线圈电阻 62Ω,线圈电流约 80 mA,设计驱动电路时请留有余量并考虑稳压/上电冲击。由于为无极性线圈,避免使用单向二极管作为线圈吸收(若采用钳位需使用双向抑制器或 RC 网路)。
  • 热管理:高频切换或高环境温度下,注意继电器发热与周围布置,必要时考虑通风或散热设计。
  • 焊接与安装:遵循制造商推荐的焊接曲线与最长承受温度/时长,以防封装或内部结构损伤;DIP 插装时确保引脚牢固并避免机械应力。

五、封装与引脚(布局建议)

  • 封装形式:DIP 结构,8 引脚,典型尺寸 29 × 12.7 mm,便于标准 PCB 孔插安装。
  • 布局建议:在继电器所在区域留出足够空隙以容纳端子及绝缘距离,功率侧走线加宽并考虑加锡或使用穿孔大铜箔以提升载流能力。高速开关或大电流回路建议使用独立走线并靠近接线端子布局以降低寄生阻抗与热累积。

六、选型建议与替代考虑

  • 若需 RoHS 合规或避免含镉触点,可咨询供应商是否有 AgSnO2 或其他环保型触点替代型号。
  • 若需更高直流电流或更强耐电弧能力,可选择专用大功率继电器或固态继电器(SSR)作为替代。
  • 在选择替代型号时,核心参数对齐:触点形式(1C)、额定电流 16A、线圈电压 5V、封装类型(DIP/PCB 插装)及工作温度范围。

总结:HF115F/005-1ZS3 为一款适用于中高电流开关场合的紧凑型 DIP 继电器,兼具较高的载流能力与通用的 5V 无极性线圈驱动,设计中需注意负载类型、灭弧保护与可能的环保合规限制。若有更具体的电路或安装环境(如频繁开关、感性负载、需 RoHS 合规等),可提供细节以便给出更精确的应用与保护建议。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

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.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
