SMD1206P050TF/13.2 产品概述
RUILON（瑞隆源）SMD1206P050TF/13.2 是一款用于电路过流保护的自恢复聚合物热敏保险丝（聚合物 PTC / PPTC），采用 1206 封装，专为空间受限但需要可靠瞬态与长期过流保护的电子系统设计。校验通过！
一、主要性能与规格
- 额定耐压（Vmax）：13.2 V
- 最大承受电流（Imax）：35 A
- 保持电流（Ihold）：0.5 A（500 mA）——在此电流下可长期工作且不动作
- 跳闸电流（Itrip）：1 A —— 达到或超过该电流水平将在额定条件下动作
- 最大耗散功率（Pd）：600 mW
- 初始态阻值（Rmin）：150 mΩ
- 跳断后阻值（R1max）：700 mΩ
- 动作时间：100 ms（典型）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 尺寸：3.6 mm × 1.9 mm × 0.8 mm（1206 标准封装）
二、工作原理与特性
该器件为自恢复式过流保护元件，在电路短路或过载时通过内阻快速升温，阻值显著上升，从而限制电流并保护电路。故障解除后随温度下降，阻值恢复至初始状态，重新允许正常电流通过。特点包括响应速度快、非一次性更换、体积小、可靠性高、适合表面贴装工艺。
三、典型应用场景
- USB/数据接口、充电接口的过流保护
- 智能手机与便携设备的电源保护
- 可穿戴与物联网终端电源防护
- 汽车电子 12V 子系统的辅助保护（需注意环境与浪涌）
- 电池包、充电器、适配器输出保护
四、封装与焊接建议
- 封装：1206 SMD，便于自动贴装与回流焊处理。尺寸 3.6×1.9×0.8 mm。
- 焊接：建议遵循通用无铅回流曲线，避免长时间超过 +260 ℃ 的高温区；为保证可靠性，焊接后进行功能性测试。
- PCB 走线：输入端应留足铜箔宽度与散热面积，必要时靠近器件加散热铜皮以降低热点温升。
五、使用与设计注意事项
- 选择时请基于实际环境温度、持续电流与瞬态冲击电流进行裕量设计，避免长期在 Ihold 较高比例负载下工作。
- 最大耐压 13.2 V，应用于高于该电压环境需谨慎或增加并联保护方案。
- 器件在动作后阻值上升到最大 700 mΩ，需确认该阻值对后端电路影响（电压降、发热）。
- 对于脉冲大、浪涌多的场合，建议通过实验验证动作次数与恢复特性。
六、可靠性与包装
RUILON 品牌生产流程与质量检验保证长期稳定性，符合 SMD 电子元件的常规可靠性要求。常见包装为卷带（适配自动贴片机），订购时请注明批次与包装数量以便追溯与生产一致性控制。

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.
