0618005.MXP 产品概述
一、产品简介
0618005.MXP 是 Littelfuse（美国力特）生产的 5×20 mm 玻璃管保险丝，额定电流 5A，额定电压 250VAC，封装标注为 D5.2×L20mm。该型号通常以“保险丝管 250V 5X20MM (P) T LBC”描述，其中“T”表示延时型（Time‑Delay），适用于存在启动浪涌电流或短时过流的场合。工作温度范围宽，适应工业与商业环境。
二、主要电气与机械参数
- 额定电流：5A
- 额定电压：250V（交流）
- 分断能力：50A @ 250VAC
- 熔断 I2t：111 A^2s（指示能量通量特性）
- 类型：玻璃管保险丝，慢断/延时（T）
- 尺寸：5×20 mm（直径 φD = 5.2 mm，长度 20 mm）
- 工作温度：-55℃ ~ +125℃
三、主要特性与优势
- 延时熔断：对短时冲击电流有容忍能力，减少因启动电流或浪涌导致的误动作。
- 稳定的分断能力：在 250VAC 工况下可提供高达 50A 的短路分断能力，满足多数控制与保护需求。
- 明确的 I2t 指标：111 A^2s 帮助工程师进行保护协调和选择下级保护元件时的能量匹配计算。
- 玻璃管外观：便于目视检查熔断状态，便于维护和更换。
- 宽温度适应：-55℃~125℃ 的工作温度满足工业级应用环境要求。
四、典型应用场景
- 工业控制设备与配电板的过流保护
- 电源模块、线性/开关电源输入端保护，特别是存在初始浪涌的电源
- 家用/商用电器、电机驱动与仪器仪表的组件级保护
- 试验台与样机板中需要可视化熔断指示的场合
五、安装与使用注意事项
- 安装前确认额定电压、额定电流与系统最大持续电流匹配，避免长期过载缩短寿命。
- 对于高环境温度或密闭空间，应参考制造商的温度修正曲线进行电流选型与退化评估。
- 玻璃管易碎，安装时避免冲击或过度夹紧，接触端子需保持良好导通。
- 更换时请使用完全相同规格（额定电流、额定电压、延时特性与分断能力）的型号以保障保护性能。
- 线路保护协调时，利用 I2t 数据与上/下游保护器件进行能量匹配计算，避免误动作或保护失效。
六、选型建议
- 若电路存在明显启动浪涌或充电电容冲击，优先选择带“T”特性的延时型。
- 对需更高短路分断能力的场合，确认 50A 分断能力是否满足，必要时选择分断能力更高的型号或在上游增加保护。
- 在关键设备或不可恢复负载上，参考制造商完整数据手册（包括时间-电流特性曲线与环境修正因素）进行最终确认与验证。
0618005.MXP 以其延时特性、可视化玻璃外观和工业级温度范围，适合对短时冲击有容忍需求且需可靠过流保护的多种应用。选型与维护时推荐参照 Littelfuse 官方技术手册以获得完整性能曲线与认证信息。

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.
