SMD0805P010TF 产品概述
一、简介
SMD0805P010TF（品牌：RUILON/瑞隆源）是一款0805封装的自恢复式聚合物正温度系数（PPTC）保护器件，标称动作/维持电流面向0.10A级别的电路过流保护。其小型化封装（长×宽×高约2.2mm×1.5mm×1.0mm）适合高密度表贴电路板，用于短路、过流瞬变保护，故障清除后可自动恢复，无需更换。
二、主要参数（关键值）
- 封装：0805（SMD）
- 初始态阻值 Rmin：0.75 Ω（750 mΩ）
- 跳断后阻值 R1max：9 Ω（最大）
- 维持电流 Ihold：100 mA（0.10 A）
- 跳闸电流 Itrip：300 mA
- 最大承受电流 Imax（脉冲能力）：30 A
- 最大工作电压 Vmax：15 V
- 最大耗散功率 Pd：500 mW
- 动作时间（典型）：1.5 s（在规定过流条件下）
- 工作温度范围：-40 ℃ ～ +85 ℃
- 外形尺寸：长度 2.2 mm，宽度 1.5 mm，高度 1.0 mm
三、产品特性
- 小尺寸、适合集成于0805焊盘的表贴布线设计；
- 自恢复特性：过流或短路消除后恢复低阻态；
- 较低的初始阻值，正常运行下功耗低；
- 能承受高达30A的瞬态脉冲，适应启动浪涌或短路冲击；
- 宽温度适应范围，适合一般消费电子与工业环境。
四、典型应用场景
- 移动设备、便携式电源与电池管理的过流保护；
- USB、音视频设备、外围接口电源保护；
- LED驱动、传感器模块、微型电源的短路防护；
- 工业控制板、通信设备中对小电流回路的可靠保护。
五、选型与使用注意
- 选型原则：Ihold（100 mA）应大于最大正常工作电流，建议留有裕量（常建议 ≥1.25×工作电流）；Itrip（300 mA）决定触发阈值，应满足系统可接受的触发灵敏度。
- 功率与温升：在接近Ihold工作时器件会产生Pd对应的温升，注意周围器件热影响及PCB散热；
- 在高频或长时间过流下，动作时间和跳断后阻值会影响系统表现，设计时需考虑恢复时间和后续电路行为；
- 封装处理：按照厂家推荐的回流焊曲线进行焊接，避免过高温度或机械应力导致性能变化；
- 电压限制：工作电压不得超过15 V，以免击穿或失效。
六、可靠性与测试建议
- 在量产前做实际工况的热-电联合测试（包括持续过流、间歇浪涌、环境温度循环）；
- 对关键项目建议进行端到端短路触发与恢复次数测试，验证自恢复性能与阻值漂移；
- 储存与运输期间避免潮湿、高温以及强烈机械冲击，开封后按SMD常规湿度敏感器件处理。

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.
