- 动作时间：≤10ms；释放时间：≤5ms
- 工作温度范围：-40℃ ~ +85℃
- 品牌：HF（宏发）
- 描述：未分类（封装信息请参见原厂数据手册）
二、产品特点
- 低功耗：360mW 线圈功率，线圈电流约30mA，适合电源受限场合。
- 高切换能力：额定可承受 10A 交流/直流负载，瞬时允许至15A，适合中等功率控制。
- 快速响应：动作/释放时间分别为10ms/5ms，适应多数开关控制场景。
- 宽温度工作：-40℃~+85℃，可靠性高，适合室内外及工业环境。
三、典型应用
- 工业控制系统中的信号和电源切换
- 家电/白电的控制回路（需按耐冲击电流选型）
- 照明及建筑电气（277VAC 条件下的负载控制）
- 低功耗继电器驱动场合与通信设备电源切换
四、选型与使用建议
- 对感性负载（电机、继电器线圈、灯镇流器等）应考虑在触点上并联 RC 抑制或使用固态吸收器，避免电弧造成触点烧蚀。
- 直流线圈驱动应并联反向二极管或其他抑制电路以保护驱动器；若用脉冲驱动注意线圈功耗与温升。
- 若长期频繁切换或承受较大浪涌电流，应适当降额使用并参考原厂电气寿命曲线。
- 安装前请确认封装、针脚及尺寸信息（当前资料中未提供封装细节），并参阅原厂数据手册的机械与电气寿命数据。

Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
