HF49FD-005-1H12 产品概述

一、产品简介

HF49FD-005-1H12 为宏发(HF)出品的小型功率继电器,封装为 SIP 型(尺寸约 20×5mm),引脚数 4,触点为一组常开(单刀单掷,SPST-NO)。该继电器体积小、线圈功耗低、响应快,适合空间受限且需频繁切换或低功耗驱动的电子设备与控制模块。

二、主要电气参数

  • 线圈电压:5V DC(无极性单线圈)
  • 线圈电阻:208Ω;额定线圈功率:120mW(线圈电流约 24mA)
  • 触点形式:一组常开(SPST-NO),触点材料:AgNi
  • 触点容量(电阻负载):5A @ 30VDC;5A @ 250VAC
  • 最大切换电压/电流:250V AC / 30V DC,最大切换电流 5A
  • 接触电阻:≤100mΩ
  • 动作/释放时间:约 10ms / 5ms
  • 工作温度范围:-40℃ ~ +85℃

三、性能特点与优势

  • 低线圈功耗(120mW),适合 MCU 直驱或电池供电系统,驱动电流仅约 24mA。
  • AgNi 触点对一般直流/交流电阻负载有良好抗氧化与耐擦伤能力,适合开关小功率电机、灯光、继电器阵列等。
  • 响应速度快(动作约 10ms),适合需要较快切换的控制场景。
  • 无极性线圈简化电路设计与接线错误风险。
  • 封装紧凑,适合 PCB 密集布置与插接式继电器板。

四、应用建议与注意事项

  • 对电感性负载(继电器线圈、电机等)建议加抑制电路(续流二极管、RC 或 TVS)以减少触点电弧并延长寿命。
  • 长期高频切换或接近最大额定电流时应考虑触点退化与发热,必要时留裕量或选更高额定的继电器。
  • 遵守最大切换电压/电流规格,避免触点熔焊或卡滞。
  • 安装时注意焊接温度与时间,保持足够绝缘间距与散热空间。

五、典型应用场景

通信设备、家电控制板、工业控制小功率回路、安防与楼宇控制、测试设备与继电器阵列等需要可靠开关且空间受限的场合。

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
