HF32F/005-HS3 产品概述
一、产品简介
HF32F/005-HS3 是宏发（HF）推出的一款超小型中功率继电器，单刀单掷常开（SPST‑NO）触点结构，5V 无极性线圈设计，适用于空间受限的电路板插装应用。外形小巧（18.4 × 10.2 mm 插件封装），在保持较高开关能力的同时兼顾低功耗与快速响应，适合工业控制、通信设备、仪表和消费类电子的中低功率开关场景。
二、主要电气参数
- 触点形式：一组常开（单刀单掷‑常开，SPST‑NO）
- 触点材料：AgNi（银镍合金）
- 接触电阻：≤100 mΩ
- 线圈电压：5V DC（无极性单线圈）
- 线圈电阻：55 Ω（典型） → 线圈电流约 90.9 mA，线圈功率约 450 mW
- 额定线圈功率：450 mW
- 触点容量（电阻负载）：5A @ 30VDC；5A @ 250VAC；10A @ 125VAC
- 最大切换电流：10A
- 最大切换电压：250V AC；30V DC
- 动作时间：约 8 ms
- 释放时间：约 5 ms
- 引脚数：4
- 工作温度范围：‑40 ℃ ～ +70 ℃
三、尺寸与封装
- 封装形式：插件（插针型）
- 外形尺寸（长 × 宽，单位 mm）：18.4 × 10.2
- 引脚数 4 根（两根为线圈，两根为常开触点），适配标准插座或焊接安装。
四、产品特点与优势
- 超小体积，利于高密度PCB布局与插装式模块化设计。
- 无极性线圈：便于电路连接，在需双向或不确定极性的场合使用更灵活（如交流驱动或不定向驱动）。
- 低线圈功耗（≈450 mW）和较低线圈电流，有利于减小驱动电路尺寸并降低能耗。
- 多档触点容量覆盖常见直流/交流负载（灯、继电器输入、继电负载等），单刀结构便于控制单回路。
- 快速响应（动作 8 ms、释放 5 ms），适合多数控制与切换应用。
五、典型应用场景
- 工业控制与继电保护小型模块
- 通信设备中继与信号切换
- 仪器仪表的开关控制
- 家电或安防设备的小功率负载控制
- PCB 插拔式继电器模块
六、选型与使用建议
- 根据实际负载特性选择额定触点容量，注意高浪涌（如电机、灯泡）或容性/感性负载的浪涌电流可能超过额定值，应留足裕量或并联使用外部抑制元件。
- 线圈反向峰值会产生感应电压，若需抑制回弹，推荐使用 RC 吸收或双向瞬态抑制器；若使用二极管钳位，需注意会使线圈驱动电路出现极性依赖（使无极性特性失效）。
- 长期工作在高温环境时，应考虑按环境温度对额定负载进行降额使用。
- 焊接与清洗时避免污染触点表面，遵循制造商的焊接工艺规范。
七、采购与技术支持

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.
