产品概述：1812L200/16DR 聚合物PTC自恢复保险丝
1812L200/16DR 是一种专为表面贴装技术（SMD）设计的聚合物PTC（正温度系数）自恢复保险丝，适用于对电流过载保护有较高要求的电路。该产品由美国力特（Littelfuse）公司制造，具有出色的性能和可靠性，是现代电子设备中不可或缺的保护元件。
基本参数
安装类型：表面贴装型（SMD），便于自动化焊接和快速组装，适合大规模生产。
电流跳断（It）：3.5A，表明在超过该电流时，保险丝会跳断，从而保护后端电路。
各种电阻：
- 初始电阻（Ri）：最小为20 mΩ，表示正常工作状态下的电阻值。
- 跳断后电阻（R1）：最大为70 mΩ，说明在过载情况下，保险丝会以该电阻阻抗保持电流。
尺寸：该保险丝的尺寸为4.55mm x 3.24mm（0.179" x 0.128"），紧凑的设计可适应各种小型化电路布局。
跳断时间：在超过跳断电流的情况下，保险丝将在2秒内跳断，以防止电路组件受到过载的损害。
最大电流（Imax）：可承载高达100A的电流，非常适合高功率应用。
最大电压（Vmax）：16V，适合低至中压电源的保护需求。
工作温度：-40°C至85°C，能够在极端环境下可靠工作，适用范围广泛。
电流保持（Ih）：最大2A，表示在正常工作情况下，保险丝能够持续承载的电流。
产品应用
1812L200/16DR 聚合物PTC自恢复保险丝广泛应用于各种电子设备中，特别是在需要电流过载保护的电路设计中，如：
- 消费电子产品：手机、平板电脑、智能家居设备等。
- 工业设备：电动工具、机器设备等。
- 汽车电子：车载电路、控制系统等。
- 通信设备：交换机、路由器等。
这种保险丝的自恢复特性使其在过载情况下能够自动复位，避免了传统保险丝需要更换的问题，从而降低了维护成本和停机时间，提高了系统的整体可靠性。此外，其符合环保标准的设计也使其成为现代电子产品的重要组成部分。
技术优势
- 自恢复特性：一旦过载情况消失，保险丝会自动恢复正常状态，无需更换，大大降低维护成本。
- 高电流承载能力：面临高达100A的瞬时电流，适用于电流突变较大的应用场景。
- 快速响应时间：快速跳断能力，能在发生故障的瞬间保护电路，避免对后续电路的损坏。
- 宽工作温度范围：广泛的工作温度范围使其在各种极端环境条件下均能稳定工作。
结论
1812L200/16DR 聚合物PTC自恢复保险丝以其先进的技术特点，出色的性能，广泛的应用范围以及易于集成的设计，成为现代电子产品中重要的保护元件。在选择合适的保险丝时，该产品无疑是值得考虑的首选之一，能够为各种项目提供优越的电流保护，增强系统的安全性和可靠性。

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.
