JQC-3FF/24VDC-1HS(551) 产品概述
一、产品简介
JQC-3FF/24VDC-1HS(551) 为宏发（HF）生产的插件式小型功率继电器，采用DIP插件封装（外形约19×15.5mm），4引脚设计，触点形式为一组常开（单刀单掷，NO）。该继电器适用于需要可靠电隔离与开关控制的小型电源与控制电路。
二、主要技术参数
- 线圈电压：24VDC
- 线圈电阻：1.6 kΩ（典型）
- 线圈功耗：360 mW（低功耗设计）
- 线圈类型：无极性单线圈（两端均可接正负）
- 触点形式：1A（SPST - 常开）
- 触点材料：AgCdO（耐弧性良好）
- 触点容量（电阻负载）：10A @ 28VDC；10A @ 277VAC
- 最大切换电流：15A
- 最大切换电压：30VDC；277VAC
- 接触电阻：≤100 mΩ
- 动作时间/释放时间：约10 ms / 5 ms
- 工作温度范围：-40 ℃ ~ +85 ℃
- 引脚数/封装：4脚，插件封装
三、性能特点
- 低功耗线圈（360 mW），适合功耗敏感或电池供电系统。
- 无极性线圈便于电路设计，接线更灵活。
- 高触点容量（10A）可满足多数中小功率负载的开关需求，同时短时可承受15A冲击电流。
- AgCdO触点在开关含火花或冲击性负载时具有较好耐久性与稳定性。
- 快速动作与释放（10 ms / 5 ms），响应速度适用于常规控制与信号切换。
四、典型应用场景
- 工业控制模块、继电器板与PLC外围接口。
- 电源管理、UPS与逆变器的小功率控制回路。
- 家用与商用电气设备中的开关控制（风扇、泵、阀门驱动等）。
- 通信与测控设备中需电隔离的信号切换。
五、选型与使用建议
- 若被切换负载为电感性或有较大浪涌电流（如电机、继电器线圈等），建议按峰值电流与触点寿命进行余量选择，必要时加外部抑制元件或选用额定更高的继电器。
- 对DC线圈驱动可采用反向抑制（二极管、RC或TVS），注意二极管会使线圈工作呈极性；若需保持无极性特性，可选用RC吸收或TVS。
- AgCdO含有镉，部分市场/行业对RoHS要求严格时需确认合规性或选择替代触点材料。
- 在高温环境或长寿命要求下，应参考厂方寿命曲线并考虑降额使用。
六、安装与可靠性注意事项
- 插件安装时确保焊接温度与时间符合元件规格以免损伤线圈或封装。
- 给出可靠接地与正确布局，尽量避免高压大电流走线靠近控制线圈以减少干扰。
- 为延长触点寿命，避免频繁在最大额定下开关高能量感性负载，可采用外部吸收回路或使用前级软启动电路。
本继电器以其小巧体积、低线圈功耗和良好触点开关能力，适合广泛的通用控制和电源管理场景。选型时请结合实际负载特性及法规合规要求确认最终方案。

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.
