HF46F/005-HS1T 产品概述

一、产品概述

HF46F/005-HS1T 为宏发(HF)出品的一款超小型中功率继电器,封装为插件式(through-hole),外形尺寸仅约 20.5 × 7 mm。该继电器采用一组常开触点(单刀单掷,SPST-NO),无极性单线圈设计,适合对体积、功耗和开关能力有平衡需求的场景。

二、主要技术参数

  • 线圈电压:5 V DC
  • 线圈电阻:125 Ω(线圈电流约 40 mA)
  • 额定线圈功率:200 mW
  • 触点形式:一组常开(单刀单掷,SPST-NO)
  • 触点容量(电阻负载):5 A @ 30 VDC;5 A @ 250 VAC
  • 最大切换电压:277 V AC / 30 V DC
  • 最大切换电流:5 A
  • 触点材料:AgSnO2(抗电弧、耐擦伤)
  • 接触电阻:≤ 100 mΩ
  • 动作时间:约 10 ms;释放时间:约 10 ms
  • 引脚数:4(两线为线圈,两线为公共/常开触点)
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、产品特点

  • 体积小巧:20.5×7 mm 封装,适合空间受限的模块化设计。
  • 低功耗线圈:200 mW 线圈功率、约 40 mA 驱动电流,便于移植到低功耗系统。
  • 无极性线圈:支持任意极性驱动,便于安装与布线。
  • 中等切换能力:触点额定 5 A(电阻负载),适合中功率负载开关。
  • 优质触点材料:AgSnO2 提升耐电弧与抗粘连性能,适合频繁通断场合。
  • 响应速度快:动作/释放时间均约 10 ms,适合控制响应要求较高的应用。

四、典型应用

  • 家用电器与小型电源开关模块
  • 仪器仪表、测试设备继电控制
  • 通讯设备与外围开关管理
  • 门禁、电源切换与保护电路
  • 各类继电器模块、控制板、接口板等通用开关场景

五、驱动与抑制建议

  • 驱动:线圈工作电压 5 V、电流约 40 mA,单片机 GPIO 长期输出 40 mA 通常不推荐,建议使用 NPN / N沟 MOSFET 驱动管或驱动器芯片,并在驱动器与控制器间加限流/保护。
  • 吸收器选择:由于继电器线圈为无极性,若需抑制反向瞬态,建议采用双向 RC 吸收(阻容缓冲)或双向 TVS,而非单向整流二极管(单向二极管会使线圈引入极性)。
  • 触点保护:切换感性或高能量负载时,应并联 RC 抑制、RC 吸收网络或 MOV、TVS,避免触点电弧造成寿命下降。对于直流感性负载,注意比额定电流更严格的降额使用或增加外部抑制。

六、安装与使用注意事项

  • 焊接与安装:插件封装,推荐合理的波峰/手工焊温与时间,避免长时间高温损伤继电器内部结构。
  • 负载匹配:遵循额定电压、电流与切换类型(AC/DC)要求,切换感性负载时应适当降额。
  • 工作环境:工作温度 -40 ℃ ~ +85 ℃,避免长时间在高温、高湿或强污染环境下工作,以延长触点寿命。
  • 试验与验证:在产品设计阶段进行实际负载的通断寿命与温升测试,确认在目标工况下的可靠性。

七、小结

HF46F/005-HS1T 是一款面向空间受限、需中等功率开关的场景设计的超小型继电器。其低功耗、无极性线圈与 5 A 触点能力使其在消费电子、工业控制、仪器设备等多种应用中具有良好适配性。设计时应注意驱动方式与触点保护方案,以确保长期可靠运行。若需进一步电气寿命、机械寿命或封装图纸等详细资料,建议参考宏发官方数据手册或向供应商索取完整规格书。

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
