HF115F/012-2ZS4 产品概述
一、产品简介
HF115F/012-2ZS4 是宏发（HF）推出的一款小型大功率直流继电器，采用双刀双掷（2C / DPDT）触点形式、8 引脚 DIP 封装（尺寸 29×12.7mm）。其设计目标是在紧凑体积下提供可靠的高电流开关能力，适用于继电保护、工业控制、电源切换、直流负载控制等场合。
二、主要电气参数
- 线圈电压：12 V（无极性单线圈）
- 线圈电阻：360 Ω（线圈电流约 33.3 mA，线圈功率 400 mW）
- 触点形式：两组转换（2C / DPDT），引脚数：8
- 触点材料：AgCdO（耐弧、适合开关电阻性和一定感性负载）
- 触点容量（电阻负载）：8 A @ 250 VAC；最大切换电压：440 V @ AC，300 V @ DC；最大切换电流：8 A
- 接触电阻：≤100 mΩ
- 动作/释放时间：动作约 15 ms，释放约 8 ms
- 工作温度范围：-40 ℃ ～ +85 ℃
三、特点与优势
- 体积小、功率高：29×12.7 mm DIP 封装在空间受限的设备中也能实现 8 A 级开关能力。
- 无极性线圈设计：线圈可双向驱动，简化部分电路设计（注意：若使用二极管吸收回路会引入极性）。
- AgCdO 触点：对直流和交流开关具有良好的抗电弧性能与可靠性。
- 快速响应：15 ms 的动作时间适合多数控制应用。
四、应用建议与注意事项
- 直流开关时建议对触点进行保护（吸收网络、RC 抑制、TVS、熔丝或缓启动）以降低电弧与延长寿命，尤其在感性负载（电机、线圈、继电器线圈）场景下应严格保护。
- 继电器虽标注 8 A，但实际长期使用时建议按负载类型与工作频率适当降额，参考厂方寿命曲线以保证可靠性。
- 线圈为无极性设计时，如需使用抑制器件建议采用双向抑制（RC 网络或双向 TVS），避免单向二极管导致极性限制。
- 焊接与安装时遵循常规 DIP 封装工艺，注意最大环境温度与热源影响，确保接线端子与 PCB 足够的铜厚以承载额定电流。
五、典型应用场景
- 工业控制与自动化设备的电源切换与信号隔离。
- 电池管理、直流配电与逆变/充电系统中的负载切换。
- 家用电器、楼宇控制、仪器仪表等需在有限空间内实现较大电流切换的场合。
- 适合 12 V 系统集成（如部分车辆电子或通信备电系统），但用于关键汽车应用时建议额外确认抗振动、寿命与认证要求。

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.
