HF33F/005-HS3 产品概述
一、产品简介
HF33F/005-HS3 是宏发（HF）出品的一款超小型中功率继电器，5V 线圈驱动、单刀单掷常开（SPST-NO）触点结构，适合空间受限且需可靠开关控制的场合。封装为插件式，外形尺寸仅 20.5 × 10.2 mm，便于在多种电路板上安装与布局。
二、主要电气参数
- 线圈电压：5 V（无极性单线圈，便于接线）
- 线圈电阻：55 Ω（线圈消耗功率约 450 mW）
- 触点形式：一组常开（单刀单掷）
- 触点材料：AgNi（银镍合金）
- 触点电阻：≤100 mΩ
- 触点容量（电阻负载）：5 A @ 30 VDC；5 A @ 250 VAC；10 A @ 125 VAC
- 最大切换电压：250 V AC / 30 V DC；最大切换电流：10 A
- 动作时间：约 8 ms；释放时间：约 5 ms
- 工作温度范围：-40 ℃ ～ +70 ℃
三、结构与封装
本型号为插件封装（through-hole），整体尺寸紧凑（20.5 × 10.2 mm），引脚数 4（含线圈与触点接口）。小型化设计便于在通信设备、继电器模块或电源板等狭小空间内布置。具体引脚排列及焊接孔位建议以厂家详细机械图为准。
四、典型应用场景
- 工业控制与自动化小功率控制回路
- 通信设备、仪器仪表的信号切换与隔离
- 家电、安防及智能家居控制模块
- 电源管理与继电器驱动模块（5V 微控制器直接驱动场合）
五、使用建议与注意事项
- 为保证寿命，应在额定触点容量范围内使用，尽量避免长期在最大额定值下频繁切换。
- 线圈为无极性设计，若电路固定极性并希望抑制线圈反向尖峰，可并联二极管；若需保持无极性特性，建议使用 RC 抑制网络或 TVS 以抑制反向尖峰而不影响极性。
- 对于感性负载（电机、继电器线圈等），建议使用外部吸收电路（缓冲电阻、电容或 TVS）以减少触点火花和延长使用寿命。
- 安装与焊接时遵循厂商推荐的温度曲线与工艺要求，避免过热引起线圈或密封损伤。
- 如需了解机械寿命、典型电寿命曲线和引脚具体排列，请参考宏发官方数据手册或咨询供应商。
HF33F/005-HS3 以其小巧尺寸、5V 低驱动功耗及良好的中等负载能力，适合需要体积紧凑且可靠切换性能的应用，是通用控制与信号切换场合的实用选择。若需进一步的电气寿命、耐压测试或机械安装信息，请获取宏发原厂完整数据手册。

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.
