Littelfuse 0891005.NXS 刀片式保险丝产品概述

一、产品核心身份与定位

Littelfuse 0891005.NXS是美国力特(Littelfuse)推出的LP Mini系列低压直流刀片式保险丝,型号中“0891”为系列代码,“005”对应额定电流5A,“NXS”标识封装与特性。该产品针对小型化、高可靠性过流保护场景设计,精准适配58V DC低压系统,是汽车电子、工业控制等领域的主流保护器件。

二、关键参数详解

2.1 电气核心参数

  • 额定电压:58V DC(明确适用于低压直流场景,如汽车辅助电源、工业低压分支);
  • 额定电流:5A(持续工作允许的最大电流,确保正常负载下不误熔断);
  • 分断能力:1kA@58V DC(故障时可安全断开的最大电流,避免电弧持续燃烧或器件损毁);
  • 熔断I²t值:22(预熔断能量,反映故障响应速度——数值越小,熔断越快,可毫秒级切断下游故障);
  • 标称冷电阻:17.21mΩ(低电阻设计,正常工作功耗极低,减少系统发热与能量损耗)。

2.2 物理与环境参数

  • 封装形式:10.0mm刀片式(小型化结构,适配紧凑PCB布局或模块内部空间);
  • 工作温度范围:-40℃至+125℃(宽温覆盖,满足汽车发动机舱、工业户外设备等高低温场景);
  • 触点材质:银合金(Ag,提升导电性能与耐腐蚀性,降低接触电阻)。

三、核心性能优势

  1. 低功耗高效能:17.21mΩ的低冷电阻显著降低正常工作时的功率损耗,避免因发热导致的性能衰减,延长器件及周边电路寿命;
  2. 快速故障保护:22的熔断I²t值确保故障电流下快速响应,可有效保护敏感元件(如传感器、微控制器),避免二次损坏;
  3. 宽温可靠性:-40℃至+125℃的工作范围,通过汽车级振动、冲击测试,适配 harsh环境(如汽车发动机舱温度波动、工业低温场景);
  4. 小型化适配:10.0mm刀片式封装体积紧凑,可集成到车载中控、工业传感器模块等小型设备中,不占用额外空间;
  5. 高安全分断:1kA@58V的分断能力可应对突发短路故障,避免电弧引燃周边器件,提升系统安全性。

四、典型应用场景

该产品主要适配以下低压直流系统:

  • 汽车电子:车载辅助电源(58V)、车身传感器(温度/压力传感器)、小型电机(车窗电机)、车载娱乐系统分支;
  • 工业控制:小型PLC输入输出模块、低压直流传感器节点、工业机器人末端执行器保护;
  • 消费电子:无人机电池管理系统、便携式储能电源分支;
  • 通信设备:边缘计算节点、小型基站低压直流分支保护。

五、可靠性与合规性

Littelfuse 0891005.NXS遵循汽车级(AEC-Q200)及工业级可靠性标准,通过温度循环、振动、湿度等测试验证;同时符合RoHS环保指令,无有害物质添加,适配全球市场需求。

该产品以“小型化、低功耗、高可靠性”为核心优势,精准匹配58V DC低压系统的过流保护需求,是汽车、工业等领域的成熟解决方案。

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
