产品概述:1812L035/30DR

一、基本信息

1812L035/30DR 是一款由美国力特(Littelfuse)制造的聚合物型自恢复保险丝,采用表面贴装(SMD)技术,封装尺寸为1812(4532公制)。该产品设计用于对电路过载和短路情况提供可靠的保护。其额定电压为30V,最大开关电流可达40A,且具备750mA的跳断电流(It),确保在安装电路中安全有效地防止电流过大造成的潜在损害。

二、关键参数

  • 安装类型:表面贴装型,适合现代电子设备的小型化和高密度化设计。
  • 电流 - 跳断 (It):750mA,意味着在该电流值以上,保险丝将立即跳断,保护后续电路不受损害。
  • 电阻 - 初始 (Ri):最小值为400mΩ,保证了高效的导电性,降低了开关损耗。
  • 电阻 - 跳断后 (R1):最大值为1.7Ω,表示保险丝一旦跳断,电流将被阻断,其阻抗大幅增加,进而有效切断电流。
  • 尺寸:0.179" 长 x 0.128" 宽(4.55mm x 3.24mm),紧凑的结构使其能够方便地集成到各种电子设备中。
  • 跳断时间:150ms,确保在过载发生时迅速切断电流,降低设备损伤风险。
  • 电流 - 最大值:40A,广泛适用于高电流应用场景。
  • 电压 - 最大值:30V,适合多种低至中压电子设备。
  • 工作温度范围:-40°C 至 85°C,保障在严苛环境下的可靠性与稳定性。
  • 电流 - 保持 (Ih):最大值为350mA,表示在正常工作条件下,该保险丝可保持350mA的电流通过。
  • 厚度(最大值):0.049"(1.25mm),使其适合于多种电子组装应用。
  • 类型:聚合物,完善了在快速反应和自恢复性能方面的需求。

三、应用场景

1812L035/30DR 聚合物自恢复保险丝广泛应用于各种电子消费品、工业设备及通信设备等领域,具体可包括:

  1. 消费电子:如智能手机、平板电脑、笔记本电脑等设备,保护电源和数据线免受过载影响。

  2. 家电产品:如冰箱、洗衣机、微波炉等,防止电流过载导致的元件损坏。

  3. 汽车电子:在汽车内部电路中,应用于汽车音响、导航系统及其他电子设备。

  4. 工业控制:可用于机械控制电路中,保护电路不受不当操作或环境影响。

  5. 通信设备:性能可靠的聚合物保险丝能够有效保护数据和信号处理电路。

四、优势与特点

  1. 自恢复功能:在过载情况下,保险丝会跳断保护电路,等电流恢复到安全范围后又能自动接通,避免了传统熔断器需要更换的问题。

  2. 快速响应时间:其150ms的跳断时间意味着可以在极短的时间内切断电流,保护后续电路不受损害。

  3. 高电流承载:能够承受高达40A的电流,适合于多种高功率应用。

  4. 尺寸小巧:以1812封装设计,使其可以适应各种高密度电路设计需求 。同时,表面贴装技术使得安装便捷、提高生产效率。

  5. 宽广的工作温度范围:-40°C 至 85°C 的工作范围使其可以在各种极端环境下正常工作,保证产品可靠性。

五、总结

1812L035/30DR 聚合物自恢复保险丝以其卓越的电气性能、小巧的尺寸以及自恢复的独特特性,成为了现代电子产品中至关重要的安全元件。无论是在消费类电子、工业控制、汽车电子还是通信设备中,其出色的性能和可靠性都确保了电路运行的安全性。选择Littelfuse的1812L035/30DR 为设计方案提供了坚实而安全的保障。

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
