HF115F/012-1HS3 产品概述

一、产品简介

HF115F/012-1HS3 是宏发(HF)推出的一款小型功率继电器,单刀单掷常开(1A,SPST-NO)触点结构,采用6引脚DIP封装(尺寸 12.7 × 29 mm)。该继电器在保持体积小、线圈功耗低的同时,具备16A 的较高触点承载能力,适合多种中大功率控制场合。

二、主要技术参数

  • 线圈电压:12 V(无极性,单线圈)
  • 线圈电阻:360 Ω(典型)
  • 线圈功率:400 mW(线圈电流约 12V / 360Ω ≈ 33.3 mA)
  • 触点形式:一组常开(1A,SPST-NO)
  • 触点容量(电阻负载):16 A @ 250 VAC
  • 最大切换电压:440 V AC;300 V DC
  • 最大切换电流:16 A
  • 触点材料:AgCdO(银钴氧化物)
  • 接触电阻:≤ 100 mΩ
  • 动作时间:约 15 ms;释放时间:约 8 ms
  • 引脚数:6
  • 封装:DIP,尺寸 12.7 × 29 mm
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、产品特点

  • 小型化、低功耗:12V 线圈仅约 33 mA 驱动电流,线圈功耗仅 400 mW,便于在低功耗系统中应用。
  • 大电流承载能力:触点可承受 16A@250VAC 的电阻性负载,适合家电、照明、泵/风扇等负载控制。
  • 无极性线圈:对驱动极性不敏感,接线更灵活(但驱动器建议按规范选配抑制器件)。
  • 可靠触点材质:AgCdO 材料在承受较大电流和电弧时表现稳定,接触寿命和耐久性良好。
  • 响应快速:操作/释放时间短,适合需要快速切换的控制场景。
  • 宽温工作:-40℃~+85℃ 的工作温度提升了产品适应环境温度变化的能力。

四、典型应用场景

  • 家用电器:电磁炉、洗衣机、空调等电源/负载切换。
  • 工业控制:小型电机、加热器、泵和风机的开关控制。
  • 照明与电源管理:大功率照明线路及电源分配切换。
  • 汽车电子(需确认振动/寿命规范):车载附件开关(在满足相关认证和耐久性要求下)。
  • 控制板与继电器模块:作为PCB上插装或插件继电器用于各种控制模块。

五、使用建议与注意事项

  • 驱动与保护:虽然线圈为无极性,但若用晶体管或驱动IC驱动直流线圈,建议并联反向续流二极管或选用RC/TVS 抑制电路以抑制反向尖峰,保护驱动器件。
  • 触点保护:在切换感性负载(电机、继电器线圈、灯等)时应加入RC 串联吸收网络、压敏电阻或 TVS,防止电弧和过电压缩短触点寿命。直流负载切换时注意 DC 路径更易产生电弧,应适当降额或增加保护。
  • 过流/浪涌:启动电流或浪涌可能超过触点额定值,选择时需考虑峰值电流和重复操作频率并据此降额使用或加外部限制元件。
  • PCB 与安装:DIP 封装适合插件和波峰/手工焊接,焊接工艺请参照厂家推荐的温度曲线和焊接时间。留意继电器周围通风与散热条件以避免长期高温影响寿命。
  • 环境与可靠性:在高湿、高粉尘或腐蚀性气体环境中使用需采取封装或防护措施;电气寿命与机械寿命数据请以厂家数据手册为准,设计时预留维护/更换策略。

六、订购信息与资料获取

  • 型号:HF115F/012-1HS3
  • 品牌:HF(宏发)

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
