HF46F-G/5-HS1T 产品概述

一、产品简介

HF46F-G/5-HS1T 是宏发(HF)推出的一款超小型插件继电器,尺寸仅为 20.5 × 7 mm,适用于对体积要求严格且需较大开关能力的场合。该型号为一组常开(1 Form A,单刀单掷常开)触点,线圈额定电压 5V,属于无极性单线圈设计,便于在不同驱动方式下使用。

二、主要技术参数

  • 线圈电压:5 V DC
  • 线圈电阻:125 Ω(典型)→ 线圈电流约 40 mA,线圈功率 200 mW
  • 触点形式:一组常开(1 Form A,SPST-NO)
  • 触点材料:AgSnO2(抗电弧、耐擦伤)
  • 触点容量(电阻负载):10 A @ 250 VAC,10 A @ 30 VDC
  • 最大切换电压:277 V AC;30 V DC
  • 最大切换电流:10 A
  • 接触电阻:≤ 100 mΩ
  • 动作/释放时间:约 10 ms / 10 ms
  • 工作温度:-40 ℃ ~ +85 ℃
  • 引脚数:4(插件)

三、性能特点

  • 小体积、高密度:20.5 × 7 mm 的紧凑封装,适合密集排列的 PCB 设计。
  • 低功耗线圈:200 mW 的线圈功耗与约 40 mA 的驱动电流,有利于降低驱动电路负担。
  • 高开关能力:触点额定 10 A,能够承载较大的交流或直流负载(在额定条件下)。
  • 良好的电弧抑制与耐久性:采用 AgSnO2 材料,适合多次开关及潮湿或轻污染环境下使用。
  • 无极性线圈:便于不同极性驱动,适配性强(若采用二极管吸收须注意极性引入)。

四、典型应用

  • 家电控制模块(微波炉、洗衣机控制板等)
  • 工业控制与自动化设备(信号切换、小功率电源控制)
  • 通信设备与测试仪器的电源/信号切换
  • 低功耗便携设备与物联网终端(需外部保护措施时仍可驱动直流负载)

五、使用与注意事项

  • 直流负载切换:DC 环境下易产生电弧,建议对直流 10 A 级别或有感性负载进行降额或增加吸收器(TVS、RC、熄弧电路)与熔断保护。
  • 线圈抑制:因线圈为无极性,若使用二极管做吸收需注意极性限制,交流或双向抑制建议选用 RC 抑制器或双向 TVS。
  • 防焊接与冲击:大电流或重负荷切换可能引起触点粘连或磨损,设计时应考虑触点保护与合理的开关频率。
  • PCB 与绝缘:继电器额定可达 277 VAC,PCB 设计时应满足相应爬电距离与耐压要求,并预留足够的安装强度与散热空间。
  • 焊接与温度:插件封装支持波峰/回流工艺时请参照 HF 的焊接曲线,避免超温造成内部性能退化。

六、封装与选型建议

HF46F-G/5-HS1T 为插件式四脚封装,适用于通孔焊接,便于维修替换。选型时关注负载类型(阻性或感性)、切换次数、环境温度及空间布局。如需更高耐久或医疗/汽车级认证,应与供应商确认对应规格型号或替代产品。

总结:HF46F-G/5-HS1T 以其超小体积、低功耗线圈与较高的触点容量,适合对尺寸和功耗要求严格但仍需承载较大开关电流的场景。合理的保护与布线能显著延长其实际使用寿命并保证系统可靠性。

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
