产品概述：Littelfuse 1206L012WR 聚合物 PTC 自恢复保险丝

概述

Littelfuse 1206L012WR 是一款高性能的聚合物 PTC（正温度系数）自恢复保险丝，专为保护电子电路免受过流和短路故障的影响。其最大工作电压为30V，适合多种应用场合，并且在广泛的工作温度范围内保持高效能。这款保险丝以其出色的特性和可靠性，成为电子设备设计中的理想选择。

主要特点

  1. 工作温度范围: 1206L012WR 的工作温度范围从 -40°C 到 85°C，使其能够在严酷环境中正常工作，适用于各种工业和消费电子产品。

  2. 电流特性:

    • 保持电流（Ih）: 最大125mA，这意味着在正常条件下，保险丝可以持续承载的电流为125mA，适合多种低功耗电路应用。
    • 跳断电流（It）: 最大290mA，超出该电流值后，保险丝会迅速跳闸，有效保护电路免受过流损害。
    • 最大电流: 1206L012WR 能够承受高达100A的瞬间电流，这使其适合高脉冲电流的应用场合。

  3. 电阻特性:

    • 初始电阻（Ri）: 最小值为1.5Ω，提供良好的导电性并允许较高的电流通过。
    • 跳断电阻（R1）: 最大值为6Ω，确保在跳闸后，电路中的电流被有效限制，减少潜在损害。

  4. 快速反应时间: 本产品的最大动作时间为200ms，能够快速响应电流过载，确保电路的安全和稳定。

  5. 封装和尺寸: 1206L012WR 采用表面贴装型封装，尺寸标记为1206（3216公制），尺寸为3.20mm x 1.65mm（长 x 宽），厚度最大为1.45mm。这种紧凑的设计使其适合各种小型电子设备和电路板，提供灵活的布局选择。

  6. 材料与耐用性: 采用聚合物材料的设计，提高了保险丝的耐用性与热稳定性，能够有效防止因环境因素导致的性能下降。

应用领域

Littelfuse 1206L012WR 聚合物 PTC 自恢复保险丝广泛应用于多种消费电子产品和工业设备，包括但不限于：

  • 手机、平板电脑等移动设备

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
