HF115F/005-2ZS4 继电器产品概述

一、基本参数

HF115F/005-2ZS4 为宏发(HF)生产的双刀双掷(2C,双刀双掷-转换)通用继电器,封装为 DIP(尺寸约 29 × 12.7 mm),引脚数 8。线圈额定电压 5V,线圈电阻 62Ω(线圈电流约 80 mA,线圈功率约 400 mW)。触点材料 AgCdO,触点电阻 ≤100 mΩ,最大切换电流 8A,触点容量(电阻负载)8A@250VAC。工作温度范围 -40℃ ~ +85℃,动作时间 15 ms,释放时间 8 ms。最大可切换电压为 440V AC、300V DC。

二、主要特性

  • 双刀双掷(DPDT)转换触点,适合需要双路隔离或切换的电路。
  • 低功耗线圈(≈400 mW),驱动电流约 80 mA,便于 MCU 或中小功率驱动器直接驱动(建议使用驱动管或驱动芯片)。
  • AgCdO 触点具有良好的耐电弧性能,适合频繁切换交流负载。
  • 宽工作温度范围,适应工业级应用环境。

三、电气与机械要点

  • 触点容量:8A@250VAC(电阻性负载),最大切换电流 8A;切换电压上限 440VAC / 300VDC。
  • 线圈特性:5V DC,62Ω,动作时间 15 ms,释放时间 8 ms。线圈标注为“无极性”,对线圈极性不敏感,但若并联整流抑制器(例如二极管)则需注意极性问题。
  • 触点电阻 ≤100 mΩ,适合低压信号与中等功率负载。

四、典型应用场景

  • 家用电器控制、继电保护与电源切换。
  • 工业控制与自动化设备中的开关模块。
  • 通信设备、仪表及测试设备的电路切换。
  • 小功率电机、加热器等交流负载的控制(在额定条件下使用)。

五、使用与选型建议

  • 驱动:线圈电流约 80 mA,建议用 NPN/PNP 或 MOSFET 驱动器,并配置适当的基/栅极限流电阻。
  • 抑制:为保护驱动电路,应对线圈采用反向二极管(若电路允许极性)或 RC/TVS 吸收器,控制释放时间和抑制反向过冲。
  • 负载匹配:对于感性负载(电机、继电线圈等),应考虑并联吸收电路或使用更高容量的继电器以降低触点烧蚀。
  • 环境:在高湿、高污染环境下应加保护罩或采取防尘措施,以延长触点寿命。

六、封装与焊接注意

  • 封装为通孔 DIP,安装方便且适合批量波峰/手工焊接。建议遵循通孔元件的焊接温度曲线,避免过热导致线圈或塑料件变形。
  • 安装时注意引脚定位与 PCB 孔位一致,焊接后检查机械可靠性与焊点质量。

七、可靠性与合规性提示

  • AgCdO 含镉,具有良好电弧耐受性,但在某些区域与标准(如严格的 RoHS 要求)可能需确认合规性与替代型号。
  • 电气与机械寿命请以厂家数据表为准;在高频率切换或高感性负载下应提前做耐久性测试。

八、小结

HF115F/005-2ZS4 是一款通用型 DIP 封装 DPDT 继电器,适合中等电流(8A)交流/直流负载的开关控制。其低功耗线圈、较快的动作/释放时间以及 AgCdO 触点使其在家电、工业控制和仪表等场景中具有良好适用性。选型时应注意负载类型、驱动方式及合规性要求,必要时与供应商确认详细寿命与环境测试数据。

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
