SMD1812P030TF 产品概述
一、产品简介
SMD1812P030TF 为 RUILON（瑞隆源）出品的自恢复保险丝（PPTC 型），封装规格为 1812（4.73 × 3.41 × 1.1 mm）。该元件用于电路过流与短路保护，一旦发生过流会在短时间内跳闸限流，待温度下降后自动恢复导通，适合对重复过流场景要求高且需自动复位的电子设备。
二、主要规格
- 最大耐压（Vmax）：30 V
- 最高通过电流（Imax）：30 A（最大瞬态承受能力，具体试验条件见厂方说明）
- 保持电流（Ihold）：300 mA（正常工作电流上限）
- 跳闸电流（Itrip）：600 mA（在标准条件下触发限流）
- 跳闸后最大阻值（R1max）：3 Ω
- 初始态阻值（Rmin）：250 mΩ（0.25 Ω）
- 功耗（Pd）：800 mW
- 动作时间：100 ms（在规定过流条件下）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 外形尺寸：4.73 mm × 3.41 mm × 1.1 mm
- 封装：1812 SMD
三、核心特性
- 自动复位：过流消除后，无需更换器件即可恢复导通，降低维护成本。
- 响应迅速：在设定过流条件下约 100 ms 级别动作，能有效保护下游器件。
- 低初始阻值：250 mΩ 的低阻值有利于减少正常工作时的压降与功耗。
- 宽温度适应性：-40 ℃ 至 +85 ℃ 的工作范围，适合多种环境使用。
四、典型应用
- 通信设备、路由器、电源模块与适配器的输入过流保护；
- 工业控制、测试设备、消费类电子的短路及异常电流防护；
- USB 或板载电源回路的热点保护与安全隔离。
五、安装与注意事项
- 焊接建议按厂家推荐回流曲线执行，避免超温或长时间高温导致性能退化。
- 布局时尽量靠近被保护电源输入端，缩短引线长度以提升保护效果。
- 对于可能出现超过 Imax 的极端故障，应配合熔断器或限流器一并设计。
- 存储与运输避免潮湿与高温，必要时做防潮处理。
六、可靠性与测试建议
- 推荐在最终应用中进行温升、寿命与多次跳闸恢复测试，验证在系统实际工况下的可靠性。
- 关注器件在高温与高频反复跳闸下的阻值漂移和复位时间，以保证长期稳定性。
SMD1812P030TF 以其自动复位、响应快和体积小的特点，适合需要重复保护且空间受限的电路应用。选择时请结合系统电流特性与厂方完整数据手册进行确认。

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.
