JQC-3FF/005-1ZS(551) 产品概述

一、产品概述

JQC-3FF/005-1ZS(551) 是宏发(HF)生产的一款小型通用继电器,采用插件(DIP)封装,外形尺寸约19×15.5mm,5 引脚、1C(单刀双掷)触点形式。该继电器为无极性单线圈设计,线圈额定电压 5V,适用于空间受限但需可靠开关控制的低功率电路中。

二、主要技术参数

  • 触点形式:一组转换(1C,单刀双掷)
  • 线圈电压:5VDC(无极性单线圈)
  • 额定线圈功率:360mW
  • 线圈电阻:70Ω
  • 接触电阻:≤100mΩ
  • 最大切换电流:10A
  • 触点容量(电阻负载):10A@28VDC;10A@277VAC
  • 最大切换电压:30VDC;277VAC
  • 动作时间:约10ms;释放时间:约5ms
  • 触点材料:AgCdO
  • 工作温度范围:-40℃ ~ +85℃
  • 引脚数:5;封装:插件(DIP),尺寸约 19×15.5mm

三、性能特点

  • 高容量小体积:在紧凑体积下提供最高 10A 的开关能力,适合交流/直流混合使用场景。
  • 快速响应:典型动作/释放时间分别为 10ms/5ms,满足一般控制响应需求。
  • 宽温区适用:-40℃ 至 +85℃,适合工业级环境。
  • 无极性线圈:安装接线更方便,不区分线圈极性。
  • 可靠触点材料:AgCdO 提供较好的抗弧及耐久性,适用于频繁切换场景。

四、典型应用

适用于家电控制、工业控制模块、通信设备、电源切换、继电保护及各种需隔离或电路切换的场合,尤其适合 PCB 插件安装的中功率开关方案。

五、安装及注意事项

  • PCB 布局时为保证散热及可靠性,建议在继电器周围保留适当间距并按厂家推荐焊盘尺寸开孔。
  • 线圈供电应控制在 5V±5% 范围内,避免长时间过压导致发热或寿命下降。
  • 触点切换感性负载时建议并联吸收元件或使用慢起动措施,减少触点电弧与冲击。
  • 储存与使用避免潮湿、强酸碱及剧烈振动环境;高温焊接时遵循回流或手工焊接温度曲线,防止损伤密封结构。

六、选型建议

  • 若需频繁切换或更高耐久性,可优先考虑继电器的寿命(操作次数)与触点材料匹配;对直流大电流场合注意触点烧结问题。
  • 对尺寸和安装方式有严格要求者,确认 19×15.5mm 插件尺寸与 PCB 孔位后再下单。

七、物料信息

  • 型号:JQC-3FF/005-1ZS(551)
  • 品牌:HF(宏发)
  • 封装:插件(DIP);引脚数:5
  • 触点材料:AgCdO

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
