1812L150/24MR 产品概述
产品简介
1812L150/24MR 是由美国力特（Littelfuse）推出的一款聚合物自恢复保险丝，适用于各种电子设备和电路保护应用。作为表面贴装型（SMD）元件，其在尺寸上采用了1812（4532公制）封装，结合优异的性能参数，使其适合于现代电子设计的需求。
基本特性
- 工作温度范围：-40°C 至 85°C，适应广泛的环境条件，确保在高温和低温环境下均能稳定工作。
- 材料类型：采用聚合物材料，具备优良的热稳定性和电气特性，能够有效防止过流和短路事故，确保电路的安全性。
- 最大电压：可承受高达24V的电气负载，适合于多种低压电源系统。
- 电流特性：
- 保持电流（Ih）：最大为1.5A，即在正常条件下能持续承受1.5A的电流而不跳断。
- 跳断电流（It）：在超过3A时，会快速跳断，防止过流情况的发生。
- 最大电流：其耐受峰值电流可达到20A，适用于瞬态电流大的应用场景。
跳断特性
- 跳断电阻：最大跳断电阻值为120mΩ，确保在跳闸后对电路的影响降至最低；
- 初始电阻值：最小初始电阻为40mΩ，展现出较低的内阻特性，有助于提高电路的效率；
- 最大动作时间：该保险丝在出现故障情况下，最大动作时间为1.5秒，快速响应能够有效防止设备损坏。
物理特性
- 封装/外壳：1812（4532公制）凹陷式设计，方便在表面贴装（SMD）应用中进行焊接。
- 尺寸：长0.179英寸（4.55mm），宽0.128英寸（3.24mm），厚度最大为0.071英寸（1.80mm），在紧凑型设计中不占据过多空间。
认证标准
该产品获得了 AEC-Q200 认证，符合汽车行业的质量标准，适合在汽车电子及其他高要求应用中使用。这不仅增强了其可靠性，还使得该产品广泛适用于工业、消费电子及电动车等领域。
应用领域

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.
