HF165FD-G/24-HY1STF 产品概述
一、产品简介
HF165FD-G/24-HY1STF 是宏发（HF）推出的一款插脚式功率继电器，封装尺寸约32.2×27.5mm。该继电器为一组常开（1A，单刀单掷-常开）触点，适用于中高电流交流电路的开关控制，结构紧凑、驱动功耗低，适合工业控制、电源管理及负载切换场景。
二、主要技术参数
- 触点形式：一组常开（1A，SPST-NO）
- 触点容量（电阻负载）：40A @ 277VAC
- 最大切换电流：40A
- 最大切换电压：277VAC
- 触点材料：AgSnO2
- 接触电阻：100 mΩ（初始值）
- 额定线圈功率：900 mW（无极性单线圈）
- 线圈电压/电阻：24 V / 660 Ω（线圈电流约36.4 mA，线圈耗散约0.87 W）
- 动作/释放时间：动作约15 ms，释放约10 ms
- 工作温度：-40℃ ~ +85℃
- 引脚数：4（插件式）
三、主要特性与优势
- 高开关能力：40A 大电流切换，适合功率负载与电源回路。
- 抗电弧触点材料：AgSnO2 对电弧与粘焊有较好耐受性，利于长寿命切换。
- 低功耗驱动：24V 线圈仅约36 mA，便于与微控制器或驱动电路直接配合。
- 宽温度范围：适应工业环境的温度要求。
- 插件封装：便于维护与更换，适合模块化设计与快速装配。
四、典型应用场景
- 工业控制设备、接触器辅助回路
- 电源管理与冗余切换（UPS、配电模块）
- 空调、热水器等家电的功率回路控制
- 照明及舵机/电机的中小功率切换（注意峰值电流处理）
五、安装与使用建议
- 驱动电路应能稳定提供24V 并限制浪涌电流，线圈两端无极性，可任意接法。
- 对感性负载或具有大浪涌电流的负载（如电机、灯等），建议并联RC缓冲或使用浪涌抑制器/熄弧装置以延长触点寿命。
- 触点切换高电流时应配合适当熔断保护，避免触点焊接或线路损坏。
- 安装时保证良好散热与环境通风，避免超出额定温度范围工作。
- 关键应用请参照宏发完整数据手册确认机械寿命、绝缘电阻与耐压等级等详细指标。
六、选型与注意事项
- 若有更高电流或更严苛寿命要求，建议选用额定更高或专用的功率继电器/接触器。
- 对交流277VAC/40A负载运行，注意考察实际负载类型（电阻性、感性或容性）并进行适当derating或保护设计。
- 最终设计前请核对厂家完整规格书及认证信息，必要时联系供应商获取样品和寿命测试数据。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
