HF32F-G/005-HS 产品概述

HF32F-G/005-HS 是宏发(HF)推出的一款小体积插件式通用继电器,采用单组常开(SPST-NO)触点设计,适合在有限空间内实现 5V 线圈控制的大电流开关场合。封装尺寸紧凑(18.4 × 10.2 mm),引脚数 4,便于传统 PCB 插件安装和自动化贴装流程。

一、主要特性

  • 单刀单掷(1组常开)触点,便于用于单路高低电平控制。
  • 线圈电压:5V,线圈功率:450 mW,线圈电阻:55 Ω(理论线圈电流约 90.9 mA)。
  • 触点最大切换能力:10 A(电阻负载下 10 A@250 VAC 或 10 A@30 VDC)。
  • 触点材料采用 AgCdO,接触电阻典型值 100 mΩ,确保良好导通性能。
  • 动作/释放时间快:动作约 8 ms,释放约 5 ms,响应性能良好。
  • 线圈类型为无极性单线圈,便于不同驱动方式使用。
  • 宽温工作范围:-40 ℃ ~ +85 ℃,适应一般工业环境。

二、关键电气与机械参数

  • 尺寸与封装:插件(DIP),外形尺寸 18.4 × 10.2 mm,4 引脚。
  • 触点形式:1 组常开(SPST-NO)。
  • 触点容量(电阻负载):10 A@250 VAC;10 A@30 VDC。
  • 最大切换电压:250 V AC / 30 V DC;最大切换电流:10 A。
  • 触点材料:AgCdO;接触电阻:≤100 mΩ(典型)。
  • 线圈功率:450 mW;线圈电阻:55 Ω;线圈电流约 90.9 mA(5 V 时)。
  • 响应时间:动作 8 ms,释放 5 ms。
  • 工作温度:-40 ℃ ~ +85 ℃。

三、典型应用场景

  • 家电控制:小家电、微波炉、洗衣机等对线路或辅助电路的开关控制(需确认 RoHS/监管要求)。
  • 工业控制:PLC 外围控制、传感器供电切换、信号切换等。
  • 仪器仪表:测试设备中小电流、高频次切换的通断控制。
  • 汽车电子(需按车规与环境要求验证):低压控制回路的继电保护或信号切换。

四、使用建议与注意事项

  • 驱动能力:线圈电流约 91 mA,驱动器(MCU、单片机 IO 或驱动晶体管)需能稳定提供该电流或采用驱动器件。建议使用驱动晶体管或三极管/场效应管,并在驱动端加入限流与保护。
  • 线圈抑制:尽管线圈标为无极性,仍建议在 DC 驱动时采用吸收元件(反向保护二极管、RC 抑制或 TVS)以抑制反向尖峰;注意二极管会延长释放时间,若需快速释放可采用 RC 或 TVS。
  • 触点材料与法规:AgCdO 触点具有良好耐焊接与耐电弧性能,但含镉(Cd),在严格 RoHS/无害化要求场合需确认合规性或选择替代触点材料。
  • 散热与环境:在高电流切换(接近 10 A)或高频率工作时注意散热与 PCB 铜箔宽度,防止触点发热或周边温升影响寿命。
  • 测试验证:在最终应用中进行实载测试(电压、电流、切换频率、环境温度)以评估接触可靠性与寿命。

五、封装与选型建议

HF32F-G/005-HS 为插件式小封装,适合空间受限的设计。选型时关注所需切换电压/电流与触点耐久性,若工作环境或法律要求限制镉含量,应与供应商确认触点材料替代或合规证书。对于需要快速响应或低抑制时间的场合,可结合外部驱动与吸收元件优化释放性能。

总结:HF32F-G/005-HS 以其紧凑体积、较高的开关容量和快速响应,适用于多种 5V 控制的通用开关应用;在高电流或受法规约束场景下,建议做额外验证与合规确认。

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
