产品概述:0451001.MRL 贴片式保险丝

基础信息

0451001.MRL 是一款由美国力特(Littelfuse)公司生产的高性能贴片式保险丝,专为现代电子设备提供可靠的过流保护。它的设计考虑了多种应用环境,并采用了高品质的材料与工艺,以确保在各种工作条件下的安全和稳定性。

关键参数

  1. 熔断 I²t:0.6029 该保险丝的熔断 I²t 值为 0.6029,表示在规定的条件下,保险丝在过流情况中达到熔断的时间特性。较低的 I²t 值意味着这款保险丝在突发过电流情况下能够迅速响应,保护下游电路不受损害。

  2. 分断能力:50A 这款保险丝具有50A的分断能力,表明它能够在电路出现短路或过载条件时,安全、有效地切断电流,避免因过电流导致的设备损坏,增强了整体电路系统的安全性。

  3. 工作温度:-55°C ~ 125°C 该保险丝的工作温度范围广泛,从极端的低温(-55°C)到高温(125°C),使其适用于多种环境应用,包括高温、低温以及极端条件下的电路保护需求。

  4. 额定电压:

    • 额定电压 DC:125V
    • 额定电压 AC:125V 这款保险丝适用于直流和交流电路,其额定电压为125V,确保其在正常工作条件下提供良好的过流保护。
  5. 额定电流:1A 保险丝的额定电流为1A,适合于低功耗电子设备。在设计时考虑到了低功率电路的热失控问题,充分保证了电路安全与可靠性。

  6. 标称冷电阻:78mΩ 该保险丝在未导电状态下的标称冷电阻为78mΩ,较低的电阻值有助于减少电能损耗,并确保电路的高效供应。

  7. 保险丝类型:快速熔断 0451001.MRL 属于快速熔断类型,能够在瞬态过流的情况下迅速切断电流,降低对电路的潜在危害,这对于保护敏感元器件至关重要。

应用场景

0451001.MRL 贴片式保险丝广泛应用于多种电子设备,包括但不限于:

  • 消费类电子产品,如手机、平板电脑、数码相机等。
  • 家用电器,包括小型家电、厨房电器等。
  • 工业设备,如控制系统、自动化设备等。
  • 汽车电子,如车载音响、导航系统等。

封装与安装

该保险丝采用SMD(表面贴装设备)封装设计,方便与各种PCB(印刷电路板)集成。其小巧的体积有助于在紧凑的电路设计中节省空间,同时确保产品的可靠性和长期稳定性。在安装过程中,需要遵循相应的焊接工艺,以保障保险丝与电路的良好连接。

品牌优势

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
