0217.400MXP 产品概述
一、产品简介
0217.400MXP 是 Littelfuse（美国力特）推出的一款 5 × 20mm 玻璃管快速熔断保险丝（Fuse Cartridge Fast Acting）。额定电流为 0.4A（400mA），额定电压 250VAC，管径约 φ5.2mm，长度 20mm，封装标识 D5.2xL20mm，常以散装（Bulk）形式供货并可装入标准 5×20mm 保险丝座或管座中替换使用。
二、主要电气与热机械参数
- 额定电流：0.4A（快速熔断）
- 额定电压：250V AC
- 熔断 I2t：0.125（典型值，单位通常为 A²s，实际数值请参照官方数据表）
- 分断能力：35A @ 250VAC（短路时的最大安全分断能力）
- 工作温度范围：-55℃ ～ +125℃
- 结构尺寸：直径 φD = 5.2mm，长度 L = 20mm
三、性能特点与优点
- 快速熔断特性，能迅速切断过流，保护敏感电子元件与半导体器件免受短路冲击。
- 低 I2t 值，释能较小，适用于对突入能量敏感的电路。
- 分断能力高（35A），可在多数家用与轻工业短路条件下安全动作。
- 玻璃外壳便于目视检查熔丝状态，便于维护与故障判定。
- 宽温范围适应严苛环境应用。
四、典型应用场景
适用于电源模块、通信设备、测量仪器、消费电子、照明电源、控制面板与 PCB 上的通用过流保护；在需要快速动作以保护敏感电路或防止元件被过流损坏的场合尤为合适。
五、选型与使用建议
- 确认是否需要快速熔断型或延时型（slow-blow）；含大量冲入电流的负载（如电机、变压器、灯泡）通常宜用延时型。
- 安装前断电并使用与管径匹配的 5×20mm 保险丝座，避免直接焊接保险丝，以防热造成误动作或损伤。
- 更换时应使用相同额定电流和分断能力的产品，优先选择原厂或同等认证型号。
- 储存避免潮湿、高温与强振动，防止玻璃管破裂或金属端帽氧化。
六、认证与数据核实
Littelfuse 为知名品牌，产品通常符合 IEC/EN 标准或通过相应认证；但具体型号的认证记录与更详细电气曲线（如时间-电流特性、温度漂移等）请以官方数据手册为准，订购前建议向供应商索取 Datasheet 验证关键参数。
七、安全与维护提示
- 禁止在带电情况下取下或插入保险丝；更换时请先断开电源。
- 如发现保险丝频繁熔断，应查找并排除根本故障，切勿用更大额定值保险丝“顶替”原型号。
- 玻璃管易碎，搬运与安装时小心轻放，避免端帽松动或接触不良。
总结：0217.400MXP 为一款性能稳定的 5×20mm 玻璃快速熔断保险丝，适合需要快速过流切断与低能量释放保护的电子电路。选型与使用时请结合电路特性与官方数据手册进行确认。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
