SMD2920P075TF/60 产品概述 — RUILON(瑞隆源)
一、产品简介
SMD2920P075TF/60 是 RUILON（瑞隆源）推出的一款 60V 级自恢复保险（Polyfuse/PPTC），封装为 2920（实际尺寸约 7.98mm × 5.44mm × 1.6mm）。该器件在正常工作时具有低阻抗，在过流或短路时快速增阻限制电流并在故障解除后自动恢复，适用于保护印制板电源线路和各种电子负载。
二、核心参数
- 额定耐压（Vmax）：60V
- 最大瞬时电流（Imax）：40A
- 保持电流（Ihold）：0.75A（750mA）
- 跳闸电流（Itrip）：1.5A
- 跳断后最大阻值（R1max）：1Ω
- 初始态最小阻值（Rmin）：100mΩ
- 消耗功率（Pd）：1.5W
- 动作时间：300ms（典型/条件相关）
- 工作温度：-40℃ ~ +85℃
- 封装尺寸：2920（长 7.98mm，宽 5.44mm，高 1.6mm）
三、主要特点
- 自恢复保护：发生过流或短路时快速限制电流，故障解除后自动冷却恢复导通，无需更换。
- 低初态阻值：典型初始阻值 0.1Ω 量级，降低正常工作损耗和发热。
- 宽电压应用：60V 额定耐压满足多种中低压系统保护需求。
- 温度与环境适应性好：工作温度范围 -40℃ 至 +85℃，适合工业级应用。
四、典型应用
- 工业控制和通信电源线路保护
- 电池管理与电源分配（需注意电压与电流匹配）
- USB/外围设备、摄像头、传感器等的过流保护
- 电机驱动接口、继电器驱动回路的短路防护（视浪涌能量选择）
五、选型与使用建议
- 根据负载稳态电流选择：常态工作电流应低于 Ihold，并留有裕量（建议至少 20% 以上余量）以避免误动作。
- 考虑浪涌与瞬态：若系统存在高幅值瞬态或启动电流，需确认 Imax 与动作时间能承受，并考虑外部限流或串联保险配合。
- 热环境与散热：在高温和密集布局下，器件升温会影响动作特性，必要时在 PCB 设计上留出散热空间。
- 使用前阅读厂商 Datasheet 并遵循推荐焊接与回流工艺，避免因高温循环或机械应力导致性能劣化。
六、封装与布局注意
封装 2920 提供较大的接触面，适合表面贴装自动化生产。焊盘设计和焊接工艺应参照 RUILON 的推荐过孔与回流参数，避免偏心焊点和冷焊。器件周围应留有散热通道和测试点，便于维护与热测量。
七、可靠性与维护
SMD2920P075TF/60 属被动自恢复元件，无需更换即可多次保护，但频繁且严重的过流会逐步改变其热电特性与阻值。建议在发生多次跳闸后检查系统根本原因并在必要时更换元件以保证长期可靠性。

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.
