产品概述：0452005.MRL 贴片式保险丝

0452005.MRL 是一款由Littelfuse（美国力特）推出的高性能贴片式保险丝，属于NANO2®系列，具体型号为Slo-Blo® Fuse 452 Series，额定电流为5A。该保险丝设计用于在电路中提供可靠的过流保护，能够有效防止器件和电路受到过负荷或短路故障导致的损坏。

基本参数

  1. 额定电流与额定电压：

    • 该保险丝的额定电流为5A，适合应用于电流要求相对较小的电子设备和电路。
    • 额定电压为AC和DC均为125V，确保在多种工作条件下的稳定性和安全性。

  2. 熔断特性：

    • 该保险丝类型为延时熔断（Slo-Blo®），即在过流初期能够承受一定的电流冲击，避免因瞬态电流而导致的误熔断，非常适合一些具有较大启动电流的设备，如电动机和变压器等。

  3. 分断能力与I²t参数：

    • 分断能力为50A，意味着在短路状态下，该保险丝能够有效地切断电流，最大程度地保护后续电路部件不受损坏。
    • I²t值为53.72，这是衡量保险丝在过载情况中能量吸收能力的重要参数，较高的值表明该产品能够在一定时间内承受更大的过载状态。

  4. 工作温度与冷电阻：

    • 工作温度范围为-55°C至125°C，确保在各种严苛环境下始终保持良好的工作性能。
    • 标称冷电阻为13.6mΩ，反映了该保险丝在正常工作条件下的电气特性，有助于减少能量损耗。

应用场景

0452005.MRL 贴片式保险丝广泛应用于各类电子设备中，特别是在需要高可靠性和长期稳定性的应用场景。具体应用包括：

  • 家电：如冰箱、洗衣机等对电流冲击敏感的家用电器。
  • 消费电子：手机充电器、平板电脑等对过载保护要求较高的电子产品。
  • 工业设备：电动工具、自动化设备等。
  • 汽车电子：汽车中的电子控制单元（ECU）和其他辅助控制模块。

封装和安装

0452005.MRL采用SMD（表面贴装器件）封装，便于自动化生产。其小巧的体积与优秀的热管理能力使其适合在密集布局的电路板上使用，同时也适用于需要高密度组件放置的现代电子设备。

总结

0452005.MRL 贴片式保险丝凭借其优越的性能和可靠性，成为电子设计师在设备过流保护中的首选元件。无论是针对突发的电流冲击还是持续的电流过载，其延时熔断特性及庞大的工作温度范围都为各种电子产品提供了强有力的保障。通过使用该保险丝，工程师能够在设计中实现更高的安全标准，降低故障风险，为最终用户提供更可靠的电气产品。选用0452005.MRL，您将为您的设备增添一层安全防护，确保其长期稳定和有效运行。

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
