JQC-3FF/12-1HS(551)产品概述

一、产品简介

JQC-3FF/12-1HS(551)为宏发(HF)出品的超小型大功率直流继电器,线圈标称电压12V,单刀单掷常开(SPST-NO)触点形式。封装为插件式(19×15.5mm),体积小巧,适合空间受限但需较大开关容量的场合。注意:该型号已标注停产,选型时请考虑可替代器件或库存情况。

二、主要技术参数

  • 线圈电压:12V DC(无极性单线圈)
  • 线圈电阻:400Ω;线圈电流≈30mA;额定线圈功率:360mW
  • 触点形式:一组常开(1A 单刀单掷 - 常开)
  • 触点材料:AgCdO(银钴氧化物)
  • 触点容量(电阻负载):10A @ 28VDC;10A @ 277VAC
  • 最大切换电压:30V DC;277V AC
  • 最大切换电流:15A(瞬时/允许峰值,需按具体应用评估)
  • 触点电阻:≤100mΩ;动作时间:≈10ms;释放时间:≈5ms
  • 引脚数:4;工作温度范围:-40℃ ~ +85℃

三、性能特点

  • 小体积高容量:19×15.5mm的插件封装,在有限空间内支持较高的交换电流与电压。
  • 低线圈功耗:360mW(约30mA),便于微控制器或低功耗驱动电路直接驱动(仍建议使用驱动器或晶体管隔离)。
  • 快速响应:典型动作/释放时间分别约10ms/5ms,适合要求响应速度的控制场景。
  • 无极性线圈:线圈为无极性设计,接线时对极性不敏感,方便布局。
  • 接触耐用:AgCdO触点对开关性能和耐电弧能力较好,适用于交流和直流电阻性负载。

四、典型应用场景

  • 工业控制模块、继电器板与接口板
  • 家电控制、电源切换与保护电路
  • 电源管理、交流负载开关(到277VAC)
  • 通讯设备、电池系统中的高电流开关(需注意直流电弧耗损)

五、安装与使用注意

  • 针脚分配:四引脚结构通常为两线圈脚、一个公共(COM)和一个常开(NO)脚,接线前请参照具体引脚图。
  • 驱动抑制:对于直流驱动建议并联吸收二极管或RC吸收网络以抑制反向电压,交流驱动采用适当的抑制方案。
  • 负载类型与寿命:在切换感性或高启动电流负载(电机、电感负载)时,会加速触点磨损,建议使用外部吸收器或按额定值适当降额。
  • 环境与散热:高温环境会降低触点容量和寿命,建议在额定工作温度范围内使用并留有通风散热空间。
  • 环保合规:AgCdO含少量重金属,采购与报废时注意相关环保法规与回收处理。

六、停产与替代建议

该型号已停产,若需替代,请与供应商或宏发官方联系确认等效型号。选型时重点匹配:线圈电压/功耗、触点容量(电流/电压)、封装尺寸和引脚兼容性。对环境友好和符合RoHS需求的替代品尤为重要。

七、总结

JQC-3FF/12-1HS(551)是一款体积小、线圈功耗低且能承担较大开关电流的插件式继电器,适合多种控制与开关场景。但因已停产,推荐尽快完成替代器件验证或采购现有库存,并在使用时关注驱动抑制与负载类型对触点寿命的影响。若需我方协助筛选同等规格的替代型号或核对引脚兼容性,可提供电路原理图和安装尺寸以便进一步确认。

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
