JFC1032-2500FS 产品概述

一、产品简介

JFC1032-2500FS 是集电通(JDTfuse)推出的一款贴片式大电流高耐压熔断器,专为对体积、可靠性和耐压要求较高的电源保护场景设计。器件为 SMD 封装,外形低矮且占板面积小,适合现代紧凑型电源模块与直流配电系统的过流保护需求。

二、主要性能参数

  • 类型:贴片式(SMD)保险丝
  • 额定电流:50 A
  • 额定电压:125 V
  • 工作温度范围:-55 ℃ ~ +125 ℃
  • 熔断能量(I2t):1946(单位按制造商标注)
  • 分断能力:500 A @ 72 VDC
  • 外形尺寸:长 10.25 mm × 宽 3.2 mm × 高 3.2 mm(封装标注 10.3×3.2 mm)
  • 品牌:JDTfuse(集电通)

这些参数表明该型号在高电流通断及直流断开能力方面具有较强的性能,能够在较苛刻的温度环境下稳定工作。

三、性能特点与优势

  • 高额定电流:50A 额定电流适用于中大功率电源和分布式直流母线保护,能承受较大的连续负载。
  • 高分断能力:500A@72VDC 的分断能力确保在短路或大过流事件时能可靠切断,降低系统风险。
  • 宽温度范围:-55℃ 至 +125℃ 的工作温度覆盖工业级至汽车级环境应用。
  • 紧凑封装:SMD 封装便于自动贴装与回流焊接,减少占板空间,适合高密度电路布局。
  • 可控熔断特性:给定的 I2t 值便于在设计中评估对浪涌电流和器件保护级别的影响。

四、应用建议与选型要点

  • 适用场景:开关电源输出保护、分布式直流母线、通信基站、电源模块保护、工业设备和部分汽车电子(需按整车标准验证)等。
  • 选型提示:在选择熔断器额定电流时,应根据实际工作电流、环境温度和PCB散热能力进行适当留裕(derating);若系统存在较大浪涌电流,需结合 I2t 与启动电流评估是否需要慢断或并联其他器件协同保护。
  • 直流断开注意:直流电弧比交流更难熄灭,器件的分断能力应充分高于可能的短路电流。

五、封装与焊接注意事项

  • 焊接方式:支持 SMT 自动贴装并采用回流焊工艺;建议按照制造商提供的回流温度曲线进行焊接,以避免对内部合金结构造成过度热影响。
  • PCB 布局:焊盘设计需保证良好导电与散热,尽量减少长而细的铜走线,以降低热阻和电压降。
  • 储存与搬运:避免机械冲击与过度弯折,防潮防静电,推荐在符合制程规范的环境中存放与使用。

六、可靠性与测试

JFC1032-2500FS 在实际应用前应通过必要的电气与环境测试验证,包括温升测试、短路分断测试与长期循环加载试验。设计时应综合考虑器件的热行为、I2t 能量释放与周围元件的耐受能力,确保系统在异常条件下的安全断开与最小破坏。

总结:JFC1032-2500FS 以其高电流承载、良好直流分断能力与宽温度适应性,适合用于对可靠性和体积有较高要求的电源保护场景。具体应用和焊接工艺建议参照厂方完整技术资料与样品验证结果。

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
