1206L300SL16ARG 产品概述

一、产品简介

1206L300SL16ARG 是陆特(LUTE)品牌的一款 1206 封装自恢复保险元件(Polyfuse / PPTC),用于低压直流线路的过流保护。产品额定耐压 16V,适合 5V、12V 及其它低压电源总线的短路与过载防护,能在发生异常电流时限制故障电流并在故障消除后自动恢复。

二、主要电气参数

  • 耐压(Vmax):16V
  • 最大电流(Imax):50A(瞬时或短时承受能力)
  • 保持电流(Ihold):3A(不发生跳闸的最大持续电流)
  • 跳闸电流(Itrip):6A(在规定条件下开始进入高阻状态的电流)
  • 消耗功率(Pd):1.2W(额定条件下的最大功耗)
  • 初始阻值(Rmin):3mΩ(常态低阻,压降小)
  • 跳断后阻值(R1max):30mΩ(进入保护后显著增阻以限制电流)
  • 动作时间:约 5s(典型触发时间,受温度和电流幅值影响)
  • 工作温度:-40℃ ~ +85℃

三、结构与封装

产品采用 1206 SMD 封装,适配常见的贴片工艺与 PCB 布局。低阻值设计保证正常工作时压降和功耗较小;跳断后阻值升高可有效限制故障电流,且为自恢复类型,无需更换即可恢复供电。

四、典型应用场景

  • USB、OTG、充电口及外设电源保护(5V/12V 系统)
  • 单板电源分配与模块保护,防止模块短路扩散
  • 汽车电子与工业低压控制线路(符合 -40℃~+85℃ 环境)
  • LED 驱动、便携设备和电池管理系统的过流防护

五、设计与使用建议

  • 选型原则:常态工作电流应明显低于 Ihold,以避免误跳闸;Itrip 应低于设备允许的最大故障电流。
  • 温度影响:工作环境温度会影响保持/跳闸电流,热源附近可能降低触发阈值,必要时留出热隔离或散热铜箔。
  • 布局:建议将器件置于靠近电源入口处,短引线并使用足够铜厚以利于散热与过流承受。
  • 焊接:采用标准回流焊工艺,遵循制造商推荐的回流曲线以保证可靠性。
  • 复位与维护:为自恢复型,故障移除后会逐步恢复低阻状态;如长期性能下降,请依据实际测试决定更换。

六、选型提示与总结

1206L300SL16ARG 以低阻、适中保持电流(3A)和较高瞬时承受能力(50A)为特征,适合对体积和贴片工艺有要求的消费类与工业类低压电源保护场合。选用时应结合系统正常工作电流、环境温度和故障电流特性进行核算,必要时做热仿真与实际过流测试以验证可靠性与动作特性。若需更详细的热性能曲线或回流焊资料,建议联系供应商获取完整规格书和应用指南。

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
