HF46F/012-HS1 产品概述

一、产品简介

HF46F/012-HS1 是宏发(HF)推出的一款超小型中功率插件继电器,线圈标称电压为 12V,单刀单掷常开(SPST-NO)触点结构。该继电器体积紧凑(封装尺寸约 20.5×7mm)、引脚数 4,适合对体积和封装密度有较高要求的电子控制应用。

二、主要参数

  • 线圈电压:12V
  • 线圈功率:200 mW(额定)
  • 线圈电阻:720 Ω
  • 线圈类型:无极性(单线圈)
  • 触点形式:一组常开(单刀单掷)
  • 触点材料:AgNi(银镍合金)
  • 触点容量(电阻负载):5A @ 30VDC;5A @ 250VAC
  • 最大切换电压:30V DC;277V AC
  • 最大切换电流:5A
  • 接触电阻:≤100 mΩ
  • 动作/释放时间:约 10 ms / 10 ms
  • 引脚数:4;封装方式:插件;外形尺寸约 20.5×7 mm
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、性能与特点

  • 低功耗线圈:200 mW 的线圈功率适合电源受限的系统,配合 720 Ω 的线圈阻值可降低驱动电流需求。
  • 无极性设计:线圈无极性,方便驱动电路设计与接线。
  • 中等功率触点:AgNi 触点在一般电阻性负载下可实现 5A 的开关能力,开关时间短(约 10 ms),适合多数控制和负载切换场景。
  • 紧凑封装:插件式 20.5×7 mm 小体积,有利于 PCB 密集布局与模块化设计。
  • 宽温特性:-40~+85 ℃ 的工作温度范围满足大多数室内外和工业环境要求。

四、典型应用场景

  • 小型电源与负载切换:用于开关电灯、风扇、小型电机等负载(在额定与安全裕度内)。
  • 通信与控制模块:继电与信号隔离,配合低功耗控制器使用。
  • 家电与办公设备:作为控制继电器实现对中低功率回路的远程或自动控制。
  • 工业控制与仪器:适用于需要小体积、高密度布置的控制系统。

五、安装与电路建议

  • 插件安装:遵循厂商引脚布局,确保焊点可靠,避免长时间高温回流焊对继电器内部结构造成影响(建议采用手工或选择兼容的波峰/回流工艺)。
  • 继电保护:对于感性负载(电机、继电器线圈等),建议在被控回路上加 RC 抑制器或二极管等吸收元件以抑制电弧与电涌,延长触点寿命;对于直流圈驱动若使用二极管吸收,请注意无极性优势与驱动逻辑的配合。
  • 负载选择:直流开关时要注意 DC 下比 AC 更易产生电弧,应适当留有安全裕度,避免长期满载开关产生过大磨损。

六、使用注意事项

  • 不要超过额定切换电压与电流(30VDC / 277VAC,最大 5A);在接近额定上限工作时应考虑降额使用以提升寿命。
  • 环境与热管理:在高温环境或密集布置的 PCB 上,需考虑散热与温升对线圈和触点寿命的影响。
  • 防护与可靠性:AgNi 触点适合一般负载,但在含硫或腐蚀性气体环境下需防护处理或选用特殊触点材料。
  • 寿命信息:具体机械寿命与电寿命请参考宏发官方完整数据手册与测试条件,不同负载类型和工作频率会显著影响实际寿命。

本产品以小体积、低线圈功耗和较好的开关能力为设计重点,适合在中低功率开关场合中作为可靠的电磁继电器组件。需要更详细的机械图、引脚定义和寿命曲线,请参考 HF(宏发)官方资料或联系供应商索取完整数据手册。

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
