1206L200/16NR自恢复保险丝产品概述

1206L200/16NR是陆特(LUTE)品牌推出的一款1206表贴封装自恢复过流保护器件,专为低压小功率电路设计,兼具小体积、低功耗与可靠保护特性,广泛适配消费电子、小型家电及工业控制等场景。

一、产品定位与核心应用场景

该器件针对16V及以下低压电路的过流保护需求,替代传统一次性保险丝,可重复恢复导通,降低维护成本。典型应用包括:

  • 消费电子:智能手机、蓝牙耳机、智能手环等便携设备的电池保护、充电电路;
  • 小型家电:智能插座、加湿器、小型充电器的过流防护;
  • 汽车电子:车载小功率模块(如USB充电口、氛围灯)的低温环境保护;
  • 工业控制:PLC小功率输出端、传感器模块的过流保护。

二、关键电气参数解析

核心参数直接决定保护性能,需结合应用场景匹配:

  1. 电压与电流规格:
    • 耐压(Vmax)16V:仅适用于16V及以下低压电路,超压可能导致器件失效;
    • 最大电流(Imax)40A:可耐受瞬时峰值电流(如浪涌),避免过流瞬间损坏;
    • 保持电流(Ihold)2A:25℃常温下,电路正常工作电流需持续低于2A,否则器件会误动作;
    • 跳闸电流(Itrip)3.5A:常温下,当电流超过3.5A时,器件会触发保护动作(阻值骤增)。
  2. 电阻与功耗:
    • 初始态阻值(Rmin)15mΩ:导通时电阻极小,压降可忽略(如2A电流下仅0.03V压降),不影响电路效率;
    • 跳断后阻值(R1max)80mΩ:保护动作后阻值提升5倍以上,有效限制故障电流;
    • 消耗功率(Pd)1.2W:正常工作时的功耗极低,不增加电路额外能耗。
  3. 动作时间:1.5s(常温):过流触发后1.5秒左右跳断,避免瞬时浪涌(如开机冲击)导致的误保护,需结合电路响应时间匹配。

三、机械封装与尺寸规格

采用1206表贴封装,尺寸为:长3.6mm×宽1.9mm×高1.6mm,体积小巧,适合高密度PCB布局(如便携设备的紧凑主板)。封装兼容回流焊、波峰焊工艺,焊接时需注意:回流焊峰值温度不超260℃,焊接时间不超10秒,避免热损伤。

四、性能特点与核心优势

  1. 自恢复特性:过流故障排除后,器件自动恢复低阻导通状态,无需更换,降低售后维护成本;
  2. 宽温工作:-40℃~+85℃的温度范围,适应极端环境(如北方冬季户外设备、高温车间);
  3. 低电阻低功耗:15mΩ初始电阻+1.2W功耗,不影响电路信号传输与效率;
  4. 高可靠性:多次过流动作后仍保持稳定性能,耐瞬时大电流冲击(40A);
  5. 小体积适配:1206封装可与其他表贴器件同板布局,满足小型化产品需求。

五、应用注意事项

为确保保护效果与器件寿命,需注意以下几点:

  1. 参数匹配:电路正常电流≤Ihold(2A)、工作电压≤Vmax(16V),高温环境下需按温度系数修正Ihold(如85℃时Ihold约1.5A);
  2. 布局建议:靠近被保护支路的输入端,减少引线电阻对保护动作的影响;
  3. 故障排除:过流跳断后,需先排查短路、过载等故障,再等待器件恢复(通常故障排除后数秒至数十秒恢复);
  4. 避免并联:不建议多只器件并联,以免电流分布不均导致部分器件提前失效。

综上,1206L200/16NR凭借小体积、低功耗与可靠的自恢复保护特性,成为低压小功率电路过流防护的优选器件,适配多种场景的紧凑化设计需求。

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
