HF115F-012-2HS4 产品概述

一、基本参数

HF115F-012-2HS4 是宏发(HF)出品的功率型小型继电器,封装为 DIP(尺寸 29×12.7mm),触点形式为两组常开(双刀单掷,2A,DPST-NO)。主要电气和机械参数如下:

  • 线圈电压:12V DC(无极性单线圈)
  • 额定线圈功率:400mW;线圈电阻:360Ω(静态电流 ≈ 12V/360Ω ≈ 33.3mA)
  • 触点材料:AgCdO,接触电阻 ≤100mΩ
  • 额定负载(电阻性):8A @ 250VAC;最大切换电流 8A
  • 最大切换电压:440V AC;300V DC
  • 工作温度范围:-40°C 至 +85°C
  • 动作/释放时间:动作约 15ms,释放约 8ms
  • 引脚数:6

二、主要特点与优势

  • 小型化 DIP 封装,便于 PCB 布局与自动化插件装配。
  • 无极性线圈,安装时不必区分极性,适用于交流或任意极性的直流驱动(注意驱动抑制方式选择)。
  • AgCdO 触点,抗电弧能力好,适合较高电压/电流的开关场合。
  • 线圈功耗低(400mW),便于在功耗受限的系统中并联多个继电器或减少驱动器负担。

三、典型应用场景

  • 家电类电源切换与控制(如洗衣机、空调控制模块)
  • 工业控制、PLC 外围模块的小功率交流或直流负载切换
  • 照明、加热器等电阻性负载的开关控制(在额定范围内)
  • 车载或通讯设备的控制用途(需注意环境温度与振动要求)

四、选型与使用建议

  • 对于感性负载(电机、继电器线圈等),建议按感性负载的额定值进行额外降额,或在触点两端并联合适的抑制元件以抑制电弧,延长寿命。
  • 线圈抑制:由于本型号为无极性线圈,推荐采用非极性的抑制措施,如 RC 抑制网络(吸收电阻-电容)或双向 TVS/压敏电阻;单向二极管会破坏无极性特性,不建议直接并联。
  • 驱动器选型:线圈驱动电流约 33mA,可用一般晶体管、驱动 IC 或 MCU 的低侧开关 MOSFET 驱动,注意设计合适的限流与抑制网络。
  • 焊接与安装:遵循制造商的焊接与清洗工艺规范,避免长时间高温暴露;在 PCB 布局时预留足够的爬电距离与散热空间,检查实际引脚间距与孔位以匹配机械尺⼨。

五、可靠性与安全注意

  • 触点寿命受开关电流、电压及负载类型影响较大,建议在设计阶段做寿命评估与现场验证。
  • 严禁长期在超出额定电压/电流或高温(>85°C)环境下使用,以免造成触点烧蚀或线圈失效。
  • 需要满足特定认证或工业级要求时,请参考宏发官方数据表与认证文件,或联系供应商确认。

六、快速规格汇总

  • 型号:HF115F-012-2HS4(HF)
  • 触点:2组常开(DPST-NO);触点材料 AgCdO;接触电阻 ≤100mΩ
  • 额定负载:8A@250VAC;最大切换电压 440VAC / 300VDC;最大切换电流 8A
  • 线圈:12V DC,无极性;功率 400mW;电阻 360Ω;动作 15ms / 释放 8ms
  • 封装:DIP,尺寸 29×12.7mm;引脚数 6;工作温度 -40~+85°C

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.

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.

Replenishment inquiry Typical RFQ workflow
