JFC1245-3100FS 产品概述

一、产品简介

JFC1245-3100FS 为集电通(JDTfuse)推出的贴片式大电流高耐压限流保护元件,专为高功率电子设备的过流、短路保护设计。体积为 SMD 封装(12.5 × 4.5mm),适用于需要高断能力与稳定熔断特性的表面贴装工艺。

二、主要参数

  • 类型:贴片式保险丝(SMD)
  • 型号:JFC1245-3100FS
  • 额定电流:100 A
  • 额定电压:125 V
  • 熔断 I2t:8080(A^2s)
  • 分断能力:100 A @ 250 VAC
  • 工作温度:-55 ℃ ~ +125 ℃
  • 外形尺寸:长度 12.45 mm,封装标称 12.5 × 4.5 mm,厚度 4.5 mm
  • 品牌:JDTfuse(集电通)

三、产品特性

  • 大电流承载能力:100A 额定电流,适合高电流路径保护。
  • 高耐压与高断能力:125V 额定电压与在 250VAC 条件下 100A 的分断能力,能应对工业与商用高压瞬态故障。
  • 明确的能量释放特性:熔断 I2t=8080,便于在系统设计时进行能量协调与选择配合元件。
  • 宽温度范围:-55 ℃ 至 +125 ℃,适合严苛环境与高温工作场景。

四、典型应用

  • 电源分配与母线保护(DC/AC 电源模块、配电板)
  • 服务器、电信设备与数据中心电源保护
  • 工业控制与自动化设备
  • 电池管理与储能系统、UPS 系统
  • 需要表面贴装、节省空间的高功率模块

五、封装与装配建议

  • 封装:SMD,兼容常规回流焊流程;为确保可靠焊接,请参照厂商数据手册推荐的焊接温度曲线与焊盘设计。
  • 装配:建议使用自动贴装机与精确贴位,焊接后避免机械应力集中。焊接与维修时注意不要对熔断体施加过度弯曲或撞击。
  • 贮存与搬运:建议常温、干燥环境保存,避免潮湿与化学物质侵蚀。长时间贮存后上板前建议目视检查焊盘与外观。

六、设计注意事项

  • 请根据系统能量(短路电流、持续时间)与 I2t 数据进行匹配,确保在故障场景下保险丝能按预期动作并保护下游元件。
  • 若需通过认证或在特定环境(汽车级、海洋、医疗等)使用,请与厂商确认相应认证与可靠性试验数据。
  • 在并联或冗余设计中,注意均流问题与熔断特性的相互影响。

如需完整电气耗散曲线、时—电特性、推荐焊接工艺与认证资料,请联系 JDTfuse(集电通)或索取 JFC1245-3100FS 的详细数据手册,以获得最终设计与制造依据。

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.

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
