宏发HFD16/12-ZFH-3N功率继电器产品概述

一、产品定位与核心属性

宏发HFD16/12-ZFH-3N是一款小型化中低功率继电器,主打「小体积、低功耗、高可靠性」,适配对PCB空间敏感、功耗控制严格的应用场景。作为宏发HFD16系列的12V线圈版本,该继电器采用DIP封装,尺寸仅15.7×10.6mm,可轻松集成到紧凑设备中,同时兼顾多组触点切换能力(3N型对应3组常闭触点),是工业控制、消费电子等领域的实用型选择。

二、核心参数详解

该继电器的关键参数明确了性能边界,核心指标如下:

  • 线圈参数:额定电压12V DC,线圈功率仅200mW(对应线圈电阻700Ω)——低功耗设计减少电路发热,适配电池供电或低功耗系统;
  • 触点参数:电阻负载下额定容量3A@30V DC、1A@125V AC;最大切换电压250V AC/220V DC,最大切换电流8A;接触电阻≤100mΩ——AgNi触点保障导通稳定,峰值8A可应对瞬时过载;
  • 时间特性:动作时间与释放时间均为5ms——快速响应满足高频通断需求;
  • 环境适应性:工作温度-40℃~+85℃——覆盖工业级、部分车载及户外设备的极端温度需求。

三、设计特点与竞争优势

  1. 超小封装:15.7×10.6mm DIP封装比常规功率继电器体积缩小30%以上,可有效节省PCB布局空间,适合智能家居、小型PLC等紧凑设备;
  2. 低功耗线圈:200mW额定功率远低于普通继电器(多数同等级产品功率≥500mW),无需额外散热设计,延长电池供电设备续航;
  3. 高可靠触点:AgNi合金触点兼具耐磨损、抗电弧特性,相比纯银触点更适合频繁切换(支持数万次通断),减少触点氧化风险;
  4. 快速响应:5ms动作/释放时间可满足传感器信号切换、小型电机控制等对响应速度要求较高的场景;
  5. 宽温适配:-40℃~+85℃工作范围通过高低温循环测试,稳定运行于北方户外、高温车间等环境。

四、典型应用场景

结合参数与设计特点,HFD16/12-ZFH-3N的典型应用包括:

  • 工业控制:小型PLC输入输出模块、传感器信号切换、小型电磁阀控制;
  • 消费电子:智能家居控制器(如智能灯控、安防门禁)、小型家电(加湿器、空气净化器)的电源切换;
  • 通信设备:基站辅助电路、路由器电源模块的通断控制;
  • 汽车电子(辅助):车载小功率负载(LED氛围灯、传感器电源)的控制(需确认汽车级认证,部分型号适配);
  • 安防设备:监控摄像头电源切换、门禁系统的信号控制。

五、可靠性与安全注意事项

该继电器的可靠性设计需注意以下要点:

  • 触点切换避免超过额定负载(电阻负载3A@30V DC),峰值8A仅适用于<1s瞬时过载;
  • 线圈电压需稳定在12V DC±10%范围内,避免过压损坏;
  • 感性负载需并联续流二极管(如1N4007),防止反电动势击穿触点;
  • 工作温度控制在-40℃~+85℃内,超出范围可能导致触点粘连或线圈失效。

总结:宏发HFD16/12-ZFH-3N以「小体积、低功耗、高可靠」为核心优势,适配多领域中低功率切换需求,是紧凑设备中替代常规继电器的优选方案。

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
