HF33F/012-ZS3 产品概述

一、产品简介

HF33F/012-ZS3 是宏发(HF)推出的一款紧凑型插件式功率继电器。为一组转换(1C,单刀双掷)触点结构,塑封(S 型)封装,常用于低功率控制与交流/直流负载切换场合。该型号未做金属过渡镀层(不渡金),绝缘等级为 B 级,适合一般工业与民用电气控制需求。

二、主要参数(概览)

  • 线圈电压:12 V DC(无极性单线圈)
  • 线圈电阻:320 Ω → 线圈电流约 12V/320Ω = 37.5 mA,线圈功率 450 mW
  • 触点形式:1C(单刀双掷,转换触点)
  • 引脚数:5
  • 触点材料:AgNi(银镍合金)
  • 最大切换电压:250 V AC / 30 V DC
  • 最大切换电流:10 A
  • 接触电阻:典型 100 mΩ
  • 动作时间:8 ms;释放时间:5 ms
  • 工作温度范围:-40 ℃ ~ +70 ℃
  • 封装与尺寸:插件式,外形 20.5 × 10.2 mm
  • 其他描述:Z 一组转换,S 塑封型,不渡金,B 级

三、电气与开关能力

HF33F 支持最高 250 VAC 和 30 VDC 的开关电压,触点额定切换电流达 10 A,采用 AgNi 材料,兼顾导电性与耐电弧性能,适合一般阻性与中等感性负载。接触电阻较低(约 100 mΩ),在功率传输和控制回路中损耗小。对于感性负载(电机、继电器线圈、电磁阀等)建议按厂方规范进行动静电流及吸收电路的降额设计。

四、线圈驱动与抑制建议

本型号线圈为无极性单线圈,方便安装,工作电流约 37.5 mA,线圈功率 450 mW,驱动电路负担小。若采用开集电极或开漏驱动器,建议并联反向续流二极管或 RC 吸收器以吸收线圈反向电动势,保护驱动器。但需注意:串联二极管会使线圈产生极性要求,若希望维持无极性特性,可使用双向抑制器(RC 或 TVS)。

五、机械与环境特性

继电器采用塑封设计,体积小巧,插件安装方便,适配紧凑 PCB 布局和标准继电器座。工作温度范围宽(-40 ℃ 至 +70 ℃),适应多数室温及工业环境。由于该型号“非金镀”触点对极低电平、微弱信号(mV 级)不做特殊保护,不建议用于超低电平信号切换或高腐蚀环境下的精密信号线。

六、典型应用场景

  • 家电与照明控制:电源切换、灯光回路控制
  • 工业控制:小型电机、执行器、传感器供电切换
  • 仪表与自动化:中等功率负载控制、继电器逻辑输出
  • 电源管理与保护回路:交流/直流负载隔离与切换

七、优点与使用注意

优点:

  • 体积小、功耗低(450 mW),易于微控制器驱动
  • 10 A 的开关能力可满足多数中等负载需求
  • 无极性线圈便于安装接线

注意事项:

  • 对于高感性或大浪涌负载(如大电机、电容性负载)应参考厂方的动静态降额及使用抑制回路
  • 非金镀触点不适合长时间切换微弱信号或在严重污染/腐蚀环境中使用
  • 加装线圈抑制元件(二极管、RC 或 TVS)可延长驱动器与继电器寿命,但需注意抑制元件可能改变线圈特性(动作/释放时间、极性要求)

八、订购与选型提示

在选型时,请确认负载类型(阻性/感性/电容性)、峰值电流及工作环境(温度、湿度、腐蚀气体),必要时按厂方数据手册对额定值进行降额设计。若需批量采购或获取最新的阻燃等级、寿命测试数据与 PCB 封装示意图,建议联系宏发(HF)授权分销或查阅官方数据手册以获得完整技术参数与验收规范。

如需我帮您整理可直接上 PCB 的引脚排布、标准电路接法或为特定负载做降额计算,可提供负载类型与工况参数,我将给出更具体的建议。

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
