1206L050/36NR 自恢复保险丝产品概述

一、产品定位与核心价值

1206L050/36NR是陆特(LUTE)推出的一款小型化贴片自恢复过流保护器件,针对低压电路(≤36V)的过流防护需求设计,兼具“快速响应”“自动复位”“低功耗”三大核心优势。它可替代传统一次性保险丝,减少故障后维护成本,同时适配高密度PCB布局的紧凑空间要求,是消费电子、汽车电子等领域的实用防护元件。

二、关键电气参数深度解析

作为过流保护核心元件,其参数直接决定防护能力,以下是关键参数的实际意义:

  1. 耐压与电流范围:最大耐压36V,覆盖12V、24V等主流低压系统;最大允许电流10A(瞬时峰值),保持电流500mA(常温下持续导通的最大工作电流),跳闸电流1A(触发动作的最小电流)——即电路正常电流需低于500mA,若电流超过1A则快速跳断。
  2. 响应与电阻特性:动作时间仅100ms,故障发生后极短时间内切断电流,避免后端IC、传感器等敏感元件损坏;正常导通时最小阻值150mΩ,跳断后最大阻值850mΩ——低导通电阻减少电路自身功耗,高阻状态有效限制故障电流扩散。
  3. 功耗与温区:最大消耗功率1W,匹配中小功率电路需求;工作温度-40℃~+85℃,可适应户外、车载等高低温环境。

三、封装与物理特性

采用1206贴片封装,实际尺寸为长3.6mm×宽1.9mm×高1.2mm,符合贴片自动化生产要求,可通过回流焊直接贴装于PCB板,能有效节省电路空间(尤其适合智能手机、便携式设备等高密度设计场景)。

四、适用场景与性能优势

(1)典型应用场景

  • 消费电子:智能手机/平板电池充放电保护、TWS耳机充电盒过流防护;
  • 汽车电子:低电压控制模块(仪表盘、传感器)过流保护;
  • 工业控制:小型传感器、PLC输入输出端过流防护;
  • 家电领域:加湿器、智能插座等小型家电电源过流保护。

(2)核心性能优势

  • 自恢复免维护:故障排除后(如短路解除)自动恢复导通,无需更换,降低售后成本;
  • 快速响应:100ms动作时间,比部分传统保险丝响应更快,保护更及时;
  • 低功耗设计:150mΩ初始阻值,避免额外发热,不影响电路正常工作;
  • 宽温适应性:-40℃~+85℃温区,满足户外、车载等复杂环境需求。

五、选型与使用注意事项

  1. 选型匹配:需确认电路工作电压≤36V,正常电流≤500mA,故障电流≥1A(确保触发跳闸);
  2. 布局建议:贴装时避免靠近大功率发热元件(功率电感、MOS管等),防止高温影响保持电流;
  3. 工艺要求:遵循标准回流焊参数(温度峰值≤260℃,时间≤10s),避免焊接损伤器件;
  4. 故障处理:跳断后先排查电路故障(短路、过载),排除后器件自动复位,无需手动操作。

这款1206L050/36NR自恢复保险丝,凭借紧凑封装、快速响应和自恢复特性,成为低压电路过流保护的高性价比选择,可广泛应用于需要小型化、免维护防护的电子设备中。

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
