HF46F-G/005-HS1 产品概述

一、产品概述

HF46F-G/005-HS1(宏发 HF)是一款超小型中功率继电器,单刀单掷常开(SPST-NO)触点结构,适用于对体积、功耗和切换能力有综合要求的 PCB 应用场景。该继电器以低线圈功耗、较大触点承载能力及宽工作温度范围为特点,适合工控、家电、仪表及通信等领域。

二、主要参数

  • 线圈电压:5V DC
  • 线圈电阻:125Ω(典型)→ 线圈电流约 40mA,线圈功率 200mW
  • 线圈类型:无极性单线圈(便于任意极性驱动)
  • 触点形式:一组常开(单刀单掷,SPST-NO)
  • 触点材料:AgNi
  • 触点容量(电阻负载):10A @ 250VAC;10A @ 30VDC
  • 最大切换电压:277VAC;30VDC
  • 最大切换电流:10A
  • 接触电阻:≤100mΩ
  • 动作时间:10ms(典型)
  • 释放时间:10ms(典型)
  • 引脚数:4(两脚线圈,两脚触点)
  • 工作温度:-40℃ ~ +85℃
  • 封装:用户提供信息中未注明,建议参考官方资料确认封装和引脚排列

三、产品特点

  • 低功耗:200mW 线圈功率,适合电池供电或功耗敏感场合。
  • 中功率承载:触点抵抗负载能力高达 10A,满足多数电器和照明负载需求。
  • 响应快:动作/释放时间约 10ms,适合需要较快切换的控制场合。
  • 无极性线圈:简化驱动电路设计,无需考虑线圈极性接线。
  • 宽温度范围与稳健触点:-40℃~+85℃ 的工作温度和 AgNi 触点材料,保证长期可靠性。

四、典型应用

  • 家用电器与照明开关控制
  • 工业控制模块、小型电源切换
  • 仪器仪表中的信号/电源断开
  • 通信设备与安防系统的开/关控制
  • 便携式设备的功率管理(注意负载类型与寿命)

五、设计与使用建议

  • 驱动:线圈电流约 40mA,可直接由 MCU IO 驱动器以外需用晶体管或驱动器放大。
  • 抑制:由于为无极性线圈,建议使用 RC 抑制器或双向 TVS;若使用二极管吸收会降低释放速度(单极性)。根据开关频率与响应要求选择抑制方式。
  • 负载类型:10A 为电阻性负载额定,感性负载(电机、电感)切换时需降额并加吸收电路(RC、TVS、浪涌抑制器)以延长触点寿命。
  • 布局与焊接:确认官方封装与引脚排列后设计 PCB,焊接和回流温度遵循厂方推荐,避免过热影响性能。
  • 可靠性:在高频次或苛刻工况下,应关注机械寿命与电寿命指标,按应用场景适当留有裕量。

六、采购与注意事项

  • 型号核对:订购前请确认完整型号 HF46F-G/005-HS1 与批号,避免混淆相近系列。
  • 查阅资料:本概述基于提供的参数,建议获取宏发官方数据手册以确认封装、机械寿命、绝缘等级、爬电距离及详细电气老化曲线。
  • 测试验证:对关键应用(大电流、感性负载、极端温度)进行样机测试,验证触点寿命与抖动、接触电阻随时间变化情况。
  • 储存与搬运:按厂家建议保存,避免潮湿和强烈振动。

如需我为您整理该型号的官方数据手册关键信息(引脚图、机械尺寸、典型电路接法)或给出 PCB 布局建议,可提供封装图或授权我查阅官方资料后继续完善。

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
