JQC-3FF/012-1ZS(551) 产品概述

一、产品简介

JQC-3FF/012-1ZS(551) 是宏发(HF)出品的一款超小型大功率电磁继电器,线圈电压12V,触点形式为一组转换(1C,单刀双掷 SPDT),适用于体积受限但需承载较大开关电流的场合。封装为插件式,外形尺寸约19×15.5mm,便于插装和更换。

二、主要电气与机械参数

  • 线圈电压:12V DC(无极性单线圈,方便布线)
  • 线圈电阻:400Ω;额定线圈功率约360mW
  • 触点形式:1C(单刀双掷,5引脚)
  • 触点容量(电阻负载):10A @ 28VDC;10A @ 277VAC
  • 最大切换电压:277V AC;30V DC
  • 最大切换电流:10A;接触电阻:≤100mΩ
  • 触点材料:AgCdO(银触点合金)
  • 动作/释放时间:动作约10ms,释放约5ms
  • 工作温度范围:-40℃ ~ +85℃

三、结构与封装

该继电器为插件封装,标准5脚布局(公共端COM、常闭NC、常开NO及两个线圈端)。尺寸紧凑(19×15.5mm),适合密集PCB布置或继电器插座直接插装,便于现场替换与维护。

四、性能亮点与优势

  • 小体积大承载:在超小封装下实现10A开关能力,适合继电控制、家电、安防设备等对体积与电流要求并重的应用。
  • 低线圈功耗:360mW线圈功耗,配合无极性线圈设计,降低驱动电路复杂度与能耗。
  • 快速响应:动作/释放时间短(约10ms/5ms),满足多数控制系统响应需求。
  • 通用交流/直流负载能力:同时具备高达277VAC与28VDC的切换能力,覆盖更多负载类型。

五、典型应用与接线提示

  • 典型应用:家用电器控制模块、通信设备电源切换、工业控制继电、照明控制及安防/门禁系统等。
  • 接线要点:识别COM、NC、NO及两线圈端;线圈为无极性,可任意方向接入12V驱动;高电流端建议采用合适线径与短路径走线,必要时加装保护熔断器。
  • 负载注意:直流开关电压最大为30V DC,直流高压应用应避免超限以防拉弧或触点粘连。

六、使用注意事项与维护建议

  • 触点材料为AgCdO(含镉氧化物),在某些环保法规或客户需求下可能受限,采购前请确认是否符合目标市场的合规要求。
  • 对感性负载(电机、继电器线圈、线性灯等)应外加抑制电路(吸收二极管、RC、TVS或浪涌抑制器),以延长触点寿命并减少干扰。
  • 在高温或高湿环境下应适当降额使用,并做可靠性验证。长期大电流开关时建议进行寿命测试以评估触点寿命衰减。
  • 安装时注意继电器座或焊点的可靠性,避免振动导致接触不良。

七、选型与采购建议

在最终选型时,请参考原厂完整数据手册确认引脚排列、外形尺寸、耐久性、绝缘电阻与冲击/振动等机械指标;如有环保合规需求(RoHS、REACH)或特殊工况(高温/高湿/频繁切换),建议向供应商确认并安排样品测试验证。

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
