HF115F/012-1HS3AF 产品概述

HF115F/012-1HS3AF 是宏发(HF)推出的一款通用型小尺寸功率继电器,采用DIP封装(29 × 12.7 × 15.7 mm),单刀单掷常开(SPST-NO,1 Form A)触点,适用于需要可靠断开或接通交流/直流负载的电路。该继电器以其紧凑尺寸、16A 大电流切换能力和低线圈功耗的组合,适合家电、照明、电源、自动化控制和工业设备等多种场景。

一、主要性能参数

  • 线圈电压:12 VDC
  • 线圈类型:无极性单线圈(可双向驱动)
  • 线圈电阻:360 Ω(典型)→ 线圈电流 ≈ 33.3 mA;线圈功率 ≈ 400 mW
  • 触点形式:一组常开(SPST-NO, 1 Form A)
  • 触点材料:AgSnO2(银锡氧化物)
  • 触点容量(电阻性负载):16 A @ 250 VAC
  • 最大切换电压:440 V AC;300 V DC
  • 最大切换电流:16 A
  • 接触电阻:≤100 mΩ(初始典型值)
  • 动作时间(典型):15 ms;释放时间:8 ms
  • 引脚数 / 封装:6 引脚,DIP 直插封装,封装基准 12.7 × 29 mm
  • 工作温度范围:-40 ℃ ~ +85 ℃

二、产品特点与优势

  • 紧凑体积:29 × 12.7 × 15.7 mm 的DIP封装便于PCB密集布局,适合空间受限的设计。
  • 大电流承载能力:触点可在250VAC下稳定切换16A电流,满足多数家电和工业负载的需求。
  • 低线圈功耗:约400 mW 的线圈功耗,配合360 Ω线圈电阻,使得单个继电器可直接由MCU驱动器或小功率驱动电路控制,节省能耗。
  • 无极性线圈:在不加二极管抑制的情况下可任意极性驱动,安装使用更灵活。
  • 优良触点材料:AgSnO2 可承受较高开关冲击及弧光,适合频繁开关和较高功率应用。

三、典型应用场景

  • 家用电器控制(洗衣机、微波炉、电热水器等)
  • 照明系统与灯具控制(线路切换、分路控制)
  • 电源与UPS 系统的直流/交流切换
  • 工业自动化与控制柜(中小功率设备开关)
  • 小型电机与风扇开关控制(注意瞬态电流与启动电流)

四、使用建议与设计注意事项

  • 驱动方式:线圈电流约为33 mA,可用单个NPN晶体管或小信号MOSFET驱动。若直接由MCU驱动,请确认GPIO允许电流能力或使用驱动器。
  • 抑制方案:该继电器为无极性线圈,若在驱动端并联二极管用于反向浪涌吸收,则驱动极性将被限定。推荐根据系统需求选择下列抑制方案:
    • 二极管(简单且低成本,但使线圈极性固定,并延长释放时间);
    • RC 抑制网络(不固定极性,可平衡动作/释放时间);
    • TVS 或瞬态抑制器(适用于需要快速释放且承受高能量脉冲的场合)。
  • 接触保护:在切换感性负载(电机、继电器线圈、变压器)时建议使用RC吸收、TVS 或外加熔断/限流器,以降低触点电蚀和延长使用寿命。
  • 安装与焊接:DIP 封装适合波峰/回流焊接,建议遵照厂商推荐的焊接曲线与清洗要求以避免对继电器性能产生影响。
  • 温度与环境:工作温度范围为 -40 ℃ 至 +85 ℃,在高湿或腐蚀性环境中应考虑封装或额外防护。

五、选型提示

  • 若负载电流接近或超过16A,应选择更高电流等级的继电器或并联多组触点,确保安全裕量。
  • 对于要求快速动作/释放或高频率切换的应用,评估抑制器类型对响应时间的影响;某些抑制方案会增加释放时间。
  • 若系统要求“无极性”特性应避免使用单向二极管做抑制;可考虑RC网络或双向TVS。

总结:HF115F/012-1HS3AF 是一款体积小、线圈功耗低且具备16A切换能力的通用功率继电器,适合在空间受限但需切换较大电流的多种电子和工业控制场景。正确的驱动与抑制设计能显著提升其可靠性与寿命。若需具体电气寿命或外形图纸(CAD/封装图)可进一步索取厂商数据手册以获取详细参数与测试规范。

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.
