SMD1206P250TF 产品概述
一、产品简介
SMD1206P250TF 是 RUILON（瑞隆源）推出的一款微型自恢复保险丝（PPTC），1206 表面贴装封装，专为低压、高可靠性短路保护场合设计。器件经过校验通过，适用于对体积、响应速度和重复性有较高要求的移动与消费电子产品电源保护。
二、主要规格参数
- 耐压（Vmax）：6 V
- 最大电流（Imax）：35 A（瞬态承受能力）
- 保持电流（Ihold）：2.5 A（在规定环境下长时间不触发）
- 跳闸电流（Itrip）：5 A（典型触发点）
- 动作时间：2 s（达到 Itrip 时的动作参考）
- 消耗功率（Pd）：800 mW（额定功耗）
- 初始态阻值（Rmin）：10 mΩ
- 跳断后阻值（R1max）：60 mΩ
- 工作温度：-40 ℃ ~ +85 ℃
- 封装尺寸：1206（长 3.6 mm × 宽 1.9 mm × 高 1.0 mm）
- 品牌：RUILON（瑞隆源）
三、功能特性
- 低电阻：初始阻值仅 10 mΩ 级，减少正常工作时的压降和发热。
- 可重复自恢复：过流触发后进入高阻状态限流，故障解除后可自动恢复，适合多次短路保护需求。
- 快速响应：在接近跳闸电流时，典型动作时间约 2 秒，能有效抑制短路和突发冲击。
- 小型化封装：1206 标准封装便于自动贴装和高密度布板，适合空间受限应用。
四、典型应用
- USB、移动电源、充电器和数据线等低压电源防护。
- 平板、笔记本以及消费类电子内部电源保护。
- 通信设备、家电小功率模块以及车载辅助电源（在符合温度与规范前提下）。
- 任何需要在 6 V 以下对瞬态大电流有短路保护需求的电路。
五、选用与安装注意
- 根据实际工作电流选择合适的 Ihold/Itrip 余量，长期工作电流应小于 Ihold，以避免误动作。
- 考虑环境温度对保留电流和动作电流的影响，高温会降低保持电流能力，应适当降额使用。
- 推荐采用良好散热和合适的焊接工艺，避免热损伤器件。
- 对于持续发生的短路故障，应查明根本原因，不应依赖自恢复保险丝作为长期容错手段。
六、可靠性与测试
本器件在 -40 ℃ 至 +85 ℃ 工作温度范围内稳定可靠，初始态与跳断后阻值在规格范围内经过测试验证。建议在量产前进行实际工况的过流、热循环与焊接兼容性验证，以确保整机可靠性符合设计要求。

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.
