HF115F/024-1ZS3 产品概述

一、产品简介

HF115F/024-1ZS3 是宏发(HF)推出的一款小型大功率继电器,属单刀双掷(1C)转换型功率继电器,适用于需要在紧凑封装内实现大电流切换的场合。封装为DIP形式,外形尺寸约29 × 12.7 mm,便于插装或波峰/回流焊接到标准印制板上。

二、主要电气参数

  • 触点形式:一组转换(1C,SPDT)
  • 线圈电压:24 V DC(无极性单线圈)
  • 线圈功率:400 mW;线圈电阻:1.44 kΩ(典型)
  • 动作/释放时间:动作约15 ms,释放约8 ms
  • 接触电阻:≤100 mΩ
  • 最大切换电流:16 A
  • 触点容量(电阻性负载):16 A @ 250 VAC
  • 最大切换电压:440 V(AC),300 V(DC)
  • 触点材料:AgCdO
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 引脚数:8

(注:线圈电流约为24 V / 1.44 kΩ ≈ 16.7 mA,与标称线圈功率400 mW一致。)

三、性能亮点

  • 大电流能力:单组触点即可支持16 A 的交流或直流切换,适合电源、马达驱动、电源路切换等应用。
  • 低接触电阻:≤100 mΩ 有利于降低接触压降和发热。
  • 宽工作温度:-40 ℃ 至 +85 ℃,适应工业级环境。
  • 无极性线圈:方便在不同驱动方案下使用(注意抑制方案会影响极性约束)。
  • 确认高耐弧材料(AgCdO):对交流和直流负载具有较好的抗电弧性能和寿命表现。

四、典型应用场景

  • 开关电源与UPS 的输出或输入换接
  • 小型直流电机或风扇的开关控制
  • 家电及暖通空调(HVAC)控制回路
  • 工业控制模块、继电器板与多路切换单元
  • 仪器仪表的电源隔离与保护电路

五、选用与使用注意事项

  • 驱动电路:继电器线圈为无极性,若在单向驱动(单片机、开关晶体管)下使用,建议并联二极管或RC 抑制网络以吸收反向感应。注意:二极管会使线圈极性变得重要;若需无极性抑制,可选用双向抑制(RC 或 TVS)。
  • 负载类型区分:接触额定值为电阻性负载的典型值,感性负载(电机、继电器线圈等)切换时会产生较大电弧,建议适当降额使用或并联吸收器以延长触点寿命。
  • 寿命与热管理:高频开关或大电流持续流过会导致触点和继电器自身发热,应评估实际通断次数及占空比,必要时留足空隙或散热措施。
  • 焊接与安装:DIP 封装便于通孔安装,建议按制造商的PCB孔位与焊接工艺进行,避免过高温度和过长时间的焊接热负荷。
  • 安全与规范:在高电压或高功率应用中,注意爬电距离和绝缘要求,遵循相关电气安全规范。

六、封装与引脚

  • 封装形式:DIP,尺寸约29 × 12.7 mm,8 引脚配置。典型引脚功能包括线圈两端、公共(COM)、常开(NO)、常闭(NC)。具体引脚排列与接线请参照厂方数据手册或样品实物标记确认。

总结:HF115F/024-1ZS3 在小尺寸下提供了可靠的16 A 切换能力,适合多种工业与民用电源控制场景。选用时应重视负载类型、驱动抑制措施与热/寿命管理,以发挥其最佳性能。若需更详细的机械尺寸、耐久性与认证信息,建议参考宏发官方数据手册或联系供应商获取完整规格文件。

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
