HF46F/005-HS1 产品概述

一、产品简介

HF46F/005-HS1 是宏发(HF)推出的一款超小型中功率继电器,单刀单掷(SPST)常开触点,适用于空间受限且需可靠开关控制的场合。凭借小巧封装和较高的开关能力,适合工业控制、通信设备、家用电器与仪表等多种应用。

二、主要参数

  • 线圈电压:5V DC
  • 线圈电阻:125Ω(线圈功率约200mW)
  • 线圈类型:无极性单线圈(便于安装)
  • 触点形式:一组常开(1A 标注为单刀单掷-常开)
  • 触点材料:AgNi(银镍合金)
  • 触点容量(电阻负载):5A @ 30VDC;5A @ 250VAC
  • 最大切换电压:277V AC;30V DC
  • 最大切换电流:5A
  • 接触电阻:≤100 mΩ
  • 动作/释放时间:约10 ms / 10 ms
  • 工作温度范围:-40℃ 至 +85℃
  • 引脚数:4(插件)
  • 封装尺寸:20.5 × 7 mm(插件封装)

三、产品特点

  • 小型化设计:20.5×7mm 的插件封装,有利于密集布置与节省 PCB 面积。
  • 低功耗线圈:线圈功率约200mW,适合对供电能力有限的系统。
  • 无极性线圈:单线圈无极性设计,简化 PCB 连线与替换维护。
  • 良好触点特性:AgNi 材料对电阻负载有较好耐久性与稳定的接触电阻。
  • 宽工作温度:-40℃~+85℃,适应工业级环境使用。
  • 快速响应:典型动作/释放时间约10ms,满足多数开关控制响应要求。

四、典型应用

  • 低电压直流电源的开关与保护(继电控制)
  • 通信设备和网络设备的线路切换
  • 电子仪表、测试设备中的信号或电源隔离
  • 家电控制模块、小型电机驱动控制(在额定范围内)
  • 汽车电子(需按温度和认证要求验证)

五、安装与使用注意事项

  • 严禁超过额定线圈电压与触点额定电压/电流工作,避免线圈过热或触点烧蚀。
  • 对于直流感性负载,建议在驱动线圈或触点侧采用适当的吸收(如二极管、RC 抑制或 TVS)以抑制反向电压和电弧,延长寿命。
  • 插件安装时注意引脚与 PCB 孔位匹配,焊接温度与时间应符合元件的热负荷能力以免损伤。
  • 运行环境应尽量避免严重潮湿、腐蚀性气体及强振动场合,必要时采取密封或减震措施。

六、可靠性与环境适应性

HF46F/005-HS1 适用于宽温工作环境,触点材料与设计对电阻性负载提供稳定性能。实际寿命受开关频率、负载类型(电感性负载会加速触点磨损)和抑制措施影响,设计时建议按实际使用工况预留裕度并进行寿命验证。

七、封装与采购建议

该型号为插件式四脚封装,外形尺寸 20.5×7mm,选型时请确认 PCB 封装图与引脚排列。采购时优先选择原厂 HF(宏发)渠道或认证分销商,若需替代品,应选择同等线圈电压(5V)、同等触点容量与相近封装的中功率继电器,并在替换前做好功能与寿命验证。

总结:HF46F/005-HS1 以其小尺寸、低线圈功耗与 5A 的切换能力,在空间受限且需可靠电气隔离的应用中具有较高的性价比。设计使用时关注驱动抑制与负载类型,可获得稳定的长期工作表现。

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
