0213004.MXP 产品概述
一、产品概览
0213004.MXP 为 Littelfuse（美国力特）213 系列慢断型（Time Lag）玻璃管保险丝，封装为 Ø5 × 20 mm 玻璃芯管，轴向引出（Axial Lead）。额定电流 4 A，额定电压 250 V，适用于需要在启动冲击电流下抗暂态冲击而又能在过流情况下可靠熔断的电路保护场景。
二、主要性能参数
- 类型：玻璃管（D5.2×L20 mm）轴向引出式保险丝
- 额定电流：4 A
- 额定电压：250 V AC（交流系统保护）
- 工作温度范围：-55 ℃ 至 +125 ℃
- 熔断能量（I2t）：226.505 A²s（用于配合上级保护与选择性协调计算）
- 最大分断能力：40 A
- 几何尺寸：直径约 5 mm，长度 20 mm（封装标注 D5.2×L20 mm）
三、产品特性与优势
- 慢断特性：能承受短时的浪涌和启动电流，避免因瞬态过流导致不必要跳闸，适配电机启动、电源滤波电容充电等场景。
- 可靠熔断：明确的 I2t 与分断能力参数，便于与电路保护协调与热应力计算。
- 宽温工作：-55 ℃ 至 +125 ℃ 的工作范围，适合工业与商用环境的温度变化。
- 标准尺寸：5×20 mm 为通用规格，便于替换与采购。
四、典型应用场景
- 开关电源与线性电源的输入保护与次级保护。
- 家用电器与消费类电子（如充电器、音响设备等）对突发浪涌的保护。
- 工业控制设备、仪器仪表中需要兼顾浪涌容忍与过流保护的电路。
- 作为模块化装置中可更换的熔断元件以便维修维护。
五、选型与使用建议
- 若电路存在显著启动电流或充电浪涌，优先选择慢断（Time Lag）型；若需快速切断短路请选快断型。
- 在高温工况下，保险丝的通过电流能力会下降，应参考厂方温升与电流-时间特性曲线并适当留有裕量。
- 使用轴向引线封装时，焊接工艺应避免对玻璃体或封端施加过大热应力或机械应力；建议按制造商的焊接温度/时间规范操作。
- 配合电路保护等级设计时，利用 I2t 数据做配合选择，保证在可能的过流事件中既能保护被保护元件又能满足选择性要求。
六、维护与备件
- 定期检查熔断情况并更换已熔断或受损的保险丝；更换时请使用与原件完全相同的额定电流、电压与特性型号。
- 采购与库存时注意防潮、防磕碰，避免玻璃管体破裂。
七、安全与合规
本型号属于常见的 5×20 mm 玻璃管保险丝封装，广泛用于需满足国际安全规范的设备中。具体认证（如 UL/CSA/EN 等）以厂方出具的型号认证信息为准，选型时请向供应商确认相关认证和测试报告。
如需更详细的电流-时间特性曲线、温度影响数据或认证证书，我可以帮助检索或整理厂方资料供工程校核使用。

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.
