HF32FA/012-HSL1 继电器(DIP 12V)产品概述

一、产品简介

HF32FA/012-HSL1 为 HF(宏发)出品的微型功率继电器,采用DIP 插装式封装(具体封装尺寸请参照厂家数据手册)。本继电器为单线圈、无极性设计,触点形式为一组常开(IEC 表示为“1A”,即单刀单掷常开),适合在空间受限的 PCB 插装电路中实现低功耗控制。

二、主要性能参数

  • 线圈电压:12V DC
  • 线圈电阻:720Ω → 线圈电流 ≈ 12V/720Ω ≈ 16.7mA;线圈功率:200mW
  • 线圈类型:无极性单线圈(可正反接)
  • 触点形式:1A(单刀单掷-常开)
  • 触点材料:AgNi(银镍合金)
  • 触点容量(电阻性负载):5A @ 30VDC;5A @ 250VAC
  • 最大切换电压:250VAC / 30VDC;最大切换电流:5A
  • 接触电阻:典型 70mΩ
  • 动作/释放时间:动作约 8ms,释放约 4ms
  • 引脚数:4(两脚线圈 + 两脚触点)
  • 工作温度范围:-40℃ 至 +85℃

三、典型应用场景

  • 小型家电与消费电子中低电压、低电流开关控制
  • 工业控制板、信号切换与逻辑隔离电路
  • 通讯设备、安防系统的电源或信号切换
  • 对体积和功耗敏感的嵌入式板级应用

四、选型与使用要点

  1. 额定与实际负载:本继电器电阻性负载额定可达5A,但对感性或有高启动电流的负载(电机、灯泡、继电器线圈等)应考虑冲击电流对触点的影响并适当降额使用。
  2. 抑制与保护:对线圈侧若需抑制反向尖峰,可并联 RC 或 TVS;若使用二极管抑制会导致线圈有极性,请注意线圈无极性特性会因此失去。对负载侧建议使用 MOV、RC 或 TVS(根据交流/直流负载不同)以延长触点寿命。
  3. PCB 布局:继电器为 DIP 插装,请按厂家引脚图布置孔距和走线,保持触点与敏感电路的隔离并预留散热空间。
  4. 环境与可靠性:工作温度 -40~+85℃,如在潮湿、高振动或高温环境长期使用,请参考厂家寿命与可靠性数据并做好防护。
  5. 引脚与接线:4 引脚结构简单,接线时注意线圈与触点的正确引出,避免误接造成控制失效。

五、包装、资料与注意事项

  • 封装:DIP(具体外形尺寸、引脚排列请以宏发官方数据手册为准)。
  • 资料建议:在设计前获取厂家数据手册确认机械尺寸、爬电距离、绝缘耐压、寿命(电寿命/机械寿命)等详细参数。
  • 注意事项:避免在超过额定电流、电压下长期工作;对感性负载应采取适当抑制措施;焊接时注意温度与时间,避免损伤线圈或密封结构。

如需电气引脚图、外形尺寸或电寿命等更详细的参数,我可以根据官方资料帮助整理并给出参考接线与抑制电路建议。

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
