HF115F-I/012-1HS3A 产品概述

一、概述

HF115F-I/012-1HS3A 是宏发(HF)出品的一款小型功率继电器,采用6引脚DIP封装(尺寸约29×12.7mm),属于单刀单掷常开(1A,单组常开)触点结构。该继电器以其较高的触点容量(16A@250VAC)、低线圈功耗及优良的接触材料(AgSnO2)而适用于家电、照明、工业控制和电源管理等需要大电流开关的场合。

二、主要参数

  • 线圈电压:12V DC(无极性单线圈)
  • 线圈功耗:400 mW
  • 线圈电阻:360 Ω
  • 触点形式:一组常开(单刀单掷)
  • 触点材料:AgSnO2
  • 触点容量(电阻负载):16A @ 250VAC
  • 最大切换电压:440V AC / 300V DC
  • 最大切换电流:16A
  • 接触电阻:≤100 mΩ
  • 动作时间:约15 ms;释放时间:约8 ms
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:DIP,6引脚,封装尺寸约29 × 12.7 mm

三、性能与特点

  • 高载流能力:16A 的触点容量可满足大多数家用电器、照明和电机驱动等高电流负载的开关要求。
  • 耐弧与抗焊接:AgSnO2 接触材料具备良好的抗电弧、抗焊接性能,适合频繁通断或稍高能量的切换场景。
  • 低线圈功耗:400 mW 的线圈功耗有利于降低系统能耗,并适配一般PLC、单片机驱动电路。线圈为无极性设计,接线更灵活。
  • 响应速度适中:动作/释放时间分别约15 ms 和8 ms,满足多数控制系统的响应需求。
  • 宽工作温度:-40 ℃~+85 ℃ 可适应较严苛的环境温度范围。

四、典型应用

  • 家用电器:电磁阀、洗衣机、微波炉等需切换大电流线路的控制回路。
  • 照明及电源:大功率灯具、照明控制箱、开关电源的输出继电控制。
  • 工业控制:电机控制、继电保护、继电器模块替换等场合。
  • 汽车电子与备用电源系统(需按DC耐压与浪涌考虑)。

五、安装与使用建议

  • 驱动与抑制:虽然线圈无极性,但若采用二极管吸收线圈反向峰值电压,须按单向驱动设计(即会影响无极性特性);在交流或高频切换场合推荐使用RC吸收、电阻+电容或MOV抑制输出端的过压及火花。
  • 负载考量:对感性负载(电机、电磁阀等)应考虑峰值冲击电流与接触磨损,建议适当留有裕量或并联吸收器件,必要时在触点上加装外部接触保护电路。
  • 安装方向与散热:保持良好散热与通风,避开高温源,避免在额定温度极限长期满载运行。
  • PCB 固定:按照制造商推荐的引脚间距与孔径设计PCB,确保焊接可靠并有机械固定措施以承受接线振动。
  • 安全与寿命:在接近最大额定值工况下,应考虑触点寿命退化与定期维护或测试。

六、结语

HF115F-I/012-1HS3A 提供了在小型封装下较高电流处理能力与稳定的接触性能,适合对体积与载流能力有双重需求的应用场景。选型时请结合具体负载类型(电阻性或感性)、开关频率与系统浪涌保护策略进行评估,必要时咨询供应商获取详细的机械图与电气寿命数据以保证设计长期可靠。

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
