0213001.MXP 产品概述 — Littelfuse 1A 250V 5×20mm 玻璃管慢熔保险丝(Cartridge Slow Blow)

一、产品简介

0213001.MXP 为 Littelfuse(美国力特)品牌的玻璃管式慢熔(Slow Blow / Time‑Delay)保险丝,规格为 5×20mm(D5×L20mm),额定电流 1A,额定电压 250VAC。该型号以玻璃管外壳便于目视检查、慢熔特性适应短时浪涌电流和较高可靠性著称,常用于需承受启动电流或冲击电流的电路保护场合。

二、关键电气与机械参数

  • 额定电流:1A
  • 额定电压:250V AC
  • 分断能力(破断电流):35A(最大安全断开能力)
  • 熔断 I2t:19.2 A2s(表示熔断能量指标,便于选择与电路的能量匹配)
  • 工作温度范围:-55℃ 至 +125℃
  • 物理尺寸:长度 20mm,直径 φ5mm(5×20mm 标准尺寸)
  • 封装标识:D5xL20mm
  • 类型:玻璃管保险丝(慢熔)

三、主要特性与优势

  • 慢熔(Time‑Delay):对短时浪涌或启动电流具有容忍能力,避免在电机启动或电容充电瞬间误熔断。
  • 透明管身:便于目视判定是否熔断,方便维护与快速检修。
  • 宽工作温度:适应工业级温度环境(-55℃ 至 +125℃),可靠性高。
  • 紧凑通用尺寸:5×20mm 为通用替换尺寸,适配多种插座/座夹和面板熔丝座。

四、典型应用场景

  • 家用与商用电器(含电机启动负载、压缩机、风扇等)
  • 电源适配器、开关电源输入侧保护(注意确认短路电流不超过 35A)
  • 仪器仪表、工业控制模块、照明电路中需抗浪涌的保护点
  • 车载非易失性电源系统(需留意额定电压与车载环境)

五、选型与使用建议

  • 短路分断能力匹配:若电路可能出现超过 35A 的故障电流,应选择分断能力更高的保险丝或并联保护/限流措施。
  • 温度与额定电流影响:在高温环境或被密闭安装时,对额定电流进行适当降额(derating),并参考厂商温度‑电流特性曲线。
  • I2t 与浪涌能量:使用熔断 I2t(19.2 A2s)评估是否能承受系统短时能量,尤其与启动电流和保护配合件(如热敏元件)共同设计。
  • 尺寸与座结构:确认所用熔丝座(面板座、PCB 插座或线缆座)兼容 5×20mm 管型;安装时保证良好接触以降低接触电阻和热量集中。

六、存储、安装与安全注意

  • 存储于干燥、常温环境,避免潮湿与强紫外线。
  • 安装前断电,选用合适熔丝座并避免过紧或过松的机械固定。
  • 熔断后请使用诊断手段查找并排除根本故障后再更换熔丝。
  • 禁止以更高电流或更高电压替代;不得用熔丝短路或绕过保护。

七、采购与替代

0213001.MXP 由 Littelfuse 提供,常见替代品需满足:慢熔特性、1A/250V、5×20mm 尺寸、熔断 I2t 及分断能力不低于原件。选型时建议参考原厂数据手册以确保时间‑电流特性匹配。

如需本型号的完整数据手册(时间‑电流曲线、环境特性、包装信息)或在具体电路中选型计算支持,可提供电路参数以便进一步核算与建议。

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
