0217.200MXP 产品概述

一、产品简介

0217.200MXP 是 Littelfuse(美国力特)出品的一款快速熔断玻璃管保险丝,面向需要快速响应过流保护的电子与电气设备。该型号为 5 × 20mm 标准玻璃管形式,封装标注为 D5.2 × L20mm,便于与常见的 5×20mm 保险丝座和夹具配合使用。产品以稳定的过流保护性能、透明壳体便于目视检查熔断状态,以及工业级工作温度范围为主要卖点,适用于多类交流/直流电路保护场合。

二、主要参数

  • 型号:0217.200MXP
  • 品牌:Littelfuse(美国力特)
  • 类型:玻璃管快熔保险丝(Fast Acting)
  • 额定电流:0.2 A(200 mA)
  • 额定电压(AC):250 V
  • 分断能力:35 A
  • 尺寸:长 20 mm;常见封装 D5.2 × L20 mm(标准 5×20mm 玻璃管)
  • 额定工作温度:-55 ℃ 至 +125 ℃
  • 包装与配套:散装(Bulk),适用于面向量产或备件需求的采购

(备注:用户提供的直径 φD=8mm 信息可用于说明含端帽或与某些保险丝座配合时的外径尺寸差异,实际玻璃管体常见直径为约 5.0–5.2 mm。)

三、关键特性

  • 快速动作(Fast Acting):对短路和突发过流能迅速开断,适合对浪涌电流不需延时承受的电路保护场景。
  • 可视化检测:透明玻璃管设计,熔断后可直接目视确认,便于维护与现场更换。
  • 工业级耐温范围:-55 ℃ 到 +125 ℃,适用于严苛环境下的长期可靠性要求。
  • 较高分断能力:35 A 的分断能力可满足一般电子设备和小功率电源在短路条件下的安全切断需要。
  • 标准封装兼容性:5×20mm(D5.2×L20mm)是行业通用规格,便于替换和与各类保险丝座/夹具配合安装。

四、典型应用场景

  • 开关电源与适配器的输入侧过流保护
  • 仪器仪表、电源模块、控制器的电路保护
  • 通信设备与网络设备的电源防护
  • 消费电子、小家电与医疗设备(按法规与认证要求选型)
  • PCB 上的局部过流保护(配合对应的 5×20mm 保险丝支架/夹具)

五、安装与使用建议

  • 更换或安装前务必断开电源,确认电路无残留电压。
  • 使用与产品匹配的 5×20mm 保险丝座或弹簧夹,保证良好接触与机械固定。
  • 替换时必须使用相同额定电流、同类型(快速熔断)及相同或更高分断能力的保险丝,切勿用导线或低规格保险元件替代。
  • 本型号为快速熔断特性,不适合用于需承受较大浪涌电流(如某些电机启动回路或大电容充电回路)而要求延时熔断的场合;此类应选用慢熔(time-lag)型号。

六、贮存与安全注意事项

  • 贮存环境应避免潮湿、高温、强日照与腐蚀性气体,常温干燥条件下保存最佳。
  • 运输与搬运过程中避免重压和剧烈振动,防止玻璃管破裂。
  • 处理破损玻璃管时注意佩戴防护手套,避免划伤或吸入细碎玻璃。
  • 现场使用应遵守所在国家/地区的电气安全规范与设备认证要求,若需认证信息请参照厂商数据表或与 Littelfuse 销售工程师确认。

七、订购信息与选型建议

  • 产品代码:0217.200MXP,品牌 Littelfuse。
  • 采购时请确认所需包装形式(散装 Bulk 或带卷装/带包装)及是否需要额外的认证资料或测试报告。
  • 在选型时考虑系统的最大持续电流、允许的浪涌电流、触发时间特性以及分断能力;若系统存在高浪涌,应优先考虑慢熔型或配合限流元件使用。
  • 建议在设计阶段预留标准 5×20mm 的保险丝座,便于后期维护与型号替换。

八、结论

0217.200MXP 为一款可靠的快速熔断玻璃管保险丝,适合需要敏捷过流响应与目视检查的常规电子与电气保护场合。凭借 Littelfuse 的制造与质量控制,结合 250V 额定电压、200mA 的额定电流以及 35A 分断能力,该型号在小功率电源与仪器保护中具有较高的实用性。选型时请结合实际电路特性与安全认证要求,必要时参照官方数据表获取更详尽的电气与时间-电流特性曲线。

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
