HF33F/024-ZS3 插件式继电器产品概述
一、产品简介
HF33F/024-ZS3 为宏发（HF）系列小型插件式功率继电器，采用5脚DIP封装（尺寸约20.5×10.2mm），触点采用AgNi材料，触点形式为一组转换（1C，单刀双掷），适合中等电流与通用开关场合。线圈标称电压24V，属于无极性单线圈设计，便于电路布局与驱动。
二、主要技术参数
- 线圈电压：24V DC（无极性）
- 线圈电阻：1.28kΩ → 线圈电流约24V/1.28kΩ ≈ 18.75mA，额定线圈功率约450mW
- 触点形式：1C（SPDT），引脚数：5（2线圈脚 + COM/NO/NC）
- 最大切换电压：250V AC，30V DC
- 最大切换电流：10A（请依负载类型与保护措施合理降额）
- 触点材料：AgNi，接触电阻典型值 ≤100mΩ
- 动作/释放时间：约8ms / 5ms
- 工作温度范围：-40℃ ～ +70℃
- 封装与安装：插件（Through-hole）
三、产品特点
- 紧凑体积，便于高密度PCB布置与替换传统继电器。
- 无极性线圈设计，简化驱动电路（但若使用单向抑制器需注意极性问题）。
- AgNi触点兼顾导电性与抗焊接性，适合一般直流/交流开关应用。
- 响应速度适中（动作8ms、释放5ms），满足大多数控制与信号切换需求。
四、典型应用场景
- 工业控制及PLC外围开关与信号切换。
- 仪器仪表、测控设备的电源与信号隔离。
- 家电控制、照明开关（建议对有灯丝或电感性负载采取保护措施）。
- 低压直流或交流电路的常规负载控制。
五、使用建议与注意事项
- 线圈驱动：线圈工作电流约18.75mA，驱动器选择应留有余量；若用晶体管或MOSFET驱动，需考虑反向电压抑制。由于线圈为无极性，推荐使用双向TVS、RC吸收网络或应力抑制器（而非单向整流二极管），以保持无极性特性。
- 触点保护：对于感性或大冲击负载（电机、继电器线圈、汞灯等），应采用吸收电路（RC、RC+TVS或RC+MOV）以减少电弧和延长触点寿命；必要时并联金属氧化物压敏电阻或RC缓冲。
- 降额使用：在高频切换或感性负载下建议将额定电流作适当降额，以延长电气寿命。
- 安装与焊接：插件式封装，推荐手工或波峰焊兼容，焊后注意清洗残留助焊剂以防潮气与漏电。保持良好通风与散热环境以利长期稳定工作。
- 安全与间隙：遵循设备整体的爬电距与绝缘要求，避免在超出额定电压环境中使用。
六、订购与资料
- 型号：HF33F/024-ZS3
- 品牌：HF（宏发）
- 封装：插件，尺寸约20.5×10.2mm，5脚DIP
- 订购前请参考厂家详细Datasheet以获取完整机械图、引脚排列图和寿命试验数据，并根据实际应用选择合适的保护与降额方案。
如需印刷电路板引脚图、典型接线图或与特定负载匹配的保护电路建议，我可以根据电路细节给出更具体的布局与设计方案。

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.
