HF46F-G/5-HS1 产品概述

HF46F-G/5-HS1 是宏发(HF)推出的一款超小型插脚式电磁继电器,线圈额定电压 5V,单组常开触点(单刀单掷 - 常开),在保持极小封装(20.5×7mm)的同时,触点输出可达 10A,适合需要高密度布板但对开关电流有较高要求的应用场景。

一、主要特点

  • 超小型封装:插脚式设计,尺寸 20.5×7mm,便于高密度 PCB 布局与插座化安装。
  • 高容量触点:阻性负载下触点容量达 10A@250VAC、10A@30VDC,最大切换电压 277VAC / 30VDC,最大切换电流 10A。
  • 低功耗线圈:额定线圈功率 200mW,线圈电阻 125Ω,线圈驱动电流约 40mA(5V/125Ω),适合 MCU 或低功耗驱动器直接驱动(需加驱动晶体管或 MOSFET 以隔离 MCU)。
  • 无极性线圈:单线圈无极性设计,线圈两端极性不敏感,便于系统连接。
  • 快速响应:动合与释放时间均约 10ms,适合中速开关控制场合。
  • 可靠材料:触点材料 AgNi(银镍),对普通阻性与轻微感性负载有良好接触性能。
  • 宽温度范围:工作温度 -40℃ 至 +85℃,适应工业环境。

二、主要技术参数(概要)

  • 触点形式:1组常开(SPST-NO),引脚数:4
  • 触点容量(阻性):10A@250VAC;10A@30VDC
  • 最大切换电压:277VAC;30VDC
  • 最大切换电流:10A
  • 线圈电压/功率/电阻:5V / 200mW / 125Ω
  • 接触电阻:≤100mΩ(典型)
  • 动作/释放时间:约 10ms / 10ms
  • 触点材料:AgNi
  • 工作温度:-40℃ ~ +85℃
  • 封装类型:插件(through-hole),尺寸 20.5×7mm

三、电气连接与驱动建议

  • 线圈驱动:5V、约 40mA 的直流驱动电流,单片机 GPIO 不建议直接承受,建议用 NPN 驱动或低侧 MOSFET,并并联适当的浪涌抑制器。
  • 抑制元件选择:由于线圈为无极性,若需抑制线圈反向脉冲,推荐使用 RC 吸收网络或双向 TVS;若使用二极管抑制,注意二极管会引入极性要求。
  • 触点保护:对感性负载(电机、继电器线圈、阀门等)应加吸收元件(RC、TVS、Freewheel 二极管 或 RCD 脉冲吸收),以减少电弧及延长触点寿命。对交流大电流开关可并联浪涌抑制或使用负载限流措施。

四、典型应用场景

  • 家电控制模块、小型电源切换、继电器矩阵
  • 工业控制板、高密度继电器阵列、楼宇控制系统
  • 通信设备的电源/信号切换、测试仪器的自动切换模块
  • 需要 5V 驱动并保持较大切换电流(最多 10A)的小型化场合

五、选型与使用注意

  • 额定容量为阻性值,频繁切换感性或容性负载会加速触点磨损,建议按实际工况选用保护电路或更高等级触点继电器。
  • 环境温度升高时需考虑电流降额;高温与连续大电流开关会影响寿命。
  • 插脚式安装时,注意焊接温度及焊接时间,避免长期过热影响线圈与封装性能。
  • 若需并联或串联使用多个继电器,请核算总浪涌电流与线缆/接触可靠性。

HF46F-G/5-HS1 在体积与开关能力之间提供了良好平衡,是追求小型化但又要求 10A 级开关能力的理想选择。选型时,请结合具体负载类型、开关频率及环境条件,设计必要的抑制与保护电路,以获得最佳可靠性与寿命。

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
