产品概述：1812L020PR 聚合物自恢复保险丝

概述

1812L020PR 是一款由美国力特（Littelfuse）公司生产的聚合物PTC（正温度系数）自恢复保险丝。该元器件主要用于提供过流保护，对于电子设备而言，其能够有效防止因意外的电流过载而导致的损坏。此保险丝不仅具有高效的保护能力，还具备极好的自恢复特性，以及广泛的工作温度范围，适合各种应用场合。

主要特性

  • 工作温度范围：-40°C 至 85°C，能够在极端气候条件下稳定工作，适用于室外和恶劣环境的应用。
  • 最大电压：30V，适用于大多数低压电子电路，确保组件的安全性。
  • 最大电流：100A，能够承受高达100A的电流，在大电流情况下不易产生故障，保证设备的可靠性。
  • 保持电流：200mA，说明在超过此电流时，保险丝将保持导通状态，避免因轻微的电流波动而误动作。
  • 跳断电流：400mA，超过此电流时将迅速切断电路，从而保护下游设备免受损害。
  • 跳断时间：最大为20ms，确保在过载情况下快速响应，有效减少潜在的损坏风险。

电阻特性

  • 初始电阻值：最小为800mΩ，当保险丝处于正常工作状态时，保持良好的导电性。
  • 跳断电阻值：最大为5Ω，表明在保险丝跳断后，电路会导入一定的阻抗，从而最小化故障电流对下游设备的影响。

封装与安装

  • 封装类型：1812（4532公制），凹陷设计，适应大多数表面贴装技术（SMT）要求。
  • 尺寸：0.179" 长 x 0.128" 宽（4.55mm x 3.24mm），厚度最大为0.039"（1.00mm），小型化设计有助于节省电路板空间，适合在紧凑型设备中使用。
  • 安装类型：表面贴装型，适合现代电子制造工艺，有助于提高生产效率。

应用领域

1812L020PR聚合物PTC自恢复保险丝广泛应用于各种电子设备中，例如：

  • 消费电子产品（如手机、平板电脑）
  • 家用电器（如洗衣机、冰箱）
  • 电源管理设备
  • 通信设备
  • 车载电子设备 这款保险丝以其高可靠性和快速响应能力，成为了广大工程师的首选保护组件，能够有效防止电流过载带来的损害。

结论

1812L020PR聚合物自恢复保险丝是现代电子设计中不可或缺的保护元件。凭借其优越的性能、全面的电气特性和可靠的工作环境适应性，它为各种电子应用提供了理想的电流保护方案。无论是在消费电子还是工业设备领域，选择Littelfuse的1812L020PR，将为您提供长效的安全保障。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
