HF46F/5-HS1T 产品概述

一、产品简介

HF46F/5-HS1T 是宏发(HF)出品的一款小型功率继电器,属于插件式封装,适用于中低功率开关场合。该继电器为单刀单掷常开(SPST-NO)触点形式,线圈工作电压为5V,设计紧凑(封装尺寸约20.5×7mm),兼具低线圈功耗与良好的开关性能,适合PCB插件安装和自动化生产线装配。

二、主要电气参数

  • 线圈电压:5V DC
  • 线圈阻抗:125Ω(线圈电阻)
  • 线圈功率(额定):200mW(低功耗设计,便于驱动)
  • 触点形式:一组常开(单刀单掷-常开),引脚数:4
  • 触点材料:AgSnO2(抗电弧、耐烧蚀性能优良)
  • 触点容量(电阻性负载):5A @ 30VDC;5A @ 250VAC
  • 最大切换电压:277VAC / 30VDC
  • 最大切换电流:5A
  • 接触电阻:100mΩ(典型/最大值)
  • 动作/释放时间:约10ms / 10ms
  • 工作温度范围:-40℃ ~ +85℃

三、结构与封装

  • 封装形式:插件(Through-hole)
  • 外形尺寸:约20.5 × 7 mm,适合紧凑PCB布局
  • 引脚数:4(便于焊接与固定)
    该继电器为无极性单线圈设计(无极性),在直流驱动时对极性不敏感,简化了电路布线要求。

四、性能特点

  • 低线圈功耗:200mW 的线圈功率有利于减少驱动功耗和热量,适合便携或低功耗系统。
  • 较高的开关能力:触点可安全切换最高5A负载(电阻性),覆盖多数控制与照明类负载。
  • 接触材料优:AgSnO2 材料在开关有感性或偶发电弧时耐损耗好,延长触点寿命。
  • 快速响应:10ms 级别的动作与释放时间,满足一般控制与保护场合响应需求。
  • 宽温度适应:-40℃ 至 +85℃,适应工业级温度环境。

五、典型应用场景

  • 工业控制与PLC 外围开关模块
  • 家用电器与智能家居控制(小功率电机、照明负载)
  • 电源管理与继电保护电路(需注意感性负载抑制)
  • 仪器仪表、通信设备继电控制回路
    在使用时需根据负载类型(电阻性/感性/电容性)确认实际寿命与保护方案。

六、选型与使用建议

  • 驱动电路:5V 线圈且功耗较低,但通常仍建议用三极管/场效应管驱动并加装反向抑制(例如并联瞬态抑制二极管或RC 吸收)以保护驱动器。若使用交流驱动或双向驱动电路,请避免单向二极管。
  • 负载类型:对于有启动浪涌(如电机、灯泡)或高感性负载,应考虑使用浪涌抑制、电流限制器或选用额定电流更高的继电器/接触器。
  • EMC 与电寿命:对频繁开关或高能量环境,建议配合外部抑弧器件(RC/TVS/时序限制)以延长触点寿命并降低干扰。
  • 布局与焊接:插件封装便于焊接与更换,PCB 布局时留足散热与绝缘距离,满足最大切换电压的爬电距和安全要求。

总结:HF46F/5-HS1T 以其小巧的封装、5V 低功耗线圈与 5A 开关能力,适用于多种中低功率控制场合。选型时应结合负载特性与使用频率,必要时采取抑弧和浪涌保护措施,以获得最佳可靠性与使用寿命。

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
