1206L175/24NR 自恢复过流保护保险丝产品概述

一、产品定位与核心功能

1206L175/24NR是陆特(LUTE)品牌推出的1206贴片封装自恢复保险丝,专为低电压(≤24V)、中等电流场景设计,核心作用是在电路出现过流(短路、过载)时快速响应,切断异常电流以保护后端敏感元器件(电池、IC、传感器等);故障排除后自动恢复导通,无需手动更换,大幅降低维护成本与系统停机时间。

二、关键电气参数深度解析

该产品参数精准匹配小型化电子设备的过流保护需求,核心参数及应用意义如下:

(1)耐压与电流规格

  • 最大耐压(Vmax):24V:适配低压直流电路(12V车载、24V工业控制、5V消费电子等),满足多数低压系统的电压安全上限;
  • 最大电流(Imax):40A:承受瞬间峰值电流(如开机浪涌)的能力,避免突发大电流直接损坏器件;
  • 保持电流(Ihold):1.75A:电路正常工作时持续不动作的最大电流——负载≤1.75A时无误触发,保证系统稳定;
  • 跳闸电流(Itrip):3.3A:过流时触发动作的最小电流——负载≥3.3A(如短路)时,保险丝在规定时间内跳断,切断异常回路。

(2)阻值与功耗特性

  • 初始阻值(Rmin):20mΩ:低初始电阻减少正常工作时的功率损耗,配合最大功耗(Pd)1.2W,有效降低系统发热;
  • 跳断后阻值(R1max):115mΩ:故障时阻值快速升高至高阻态切断电流,故障排除后自动回落至初始低阻,恢复导通。

(3)动作时间与响应性

  • 动作时间:1.5s:在跳闸电流(3.3A)下,从过流触发到完全跳断的时间约1.5秒——既避免瞬间浪涌(如开机冲击)误触发,又能在短路等严重故障时快速响应,保护后端器件。

三、1206封装的尺寸与贴装优势

1206封装是电子行业通用小型贴片封装,1206L175/24NR的物理尺寸为3.6mm(长)×1.9mm(宽)×1.6mm(高),具备三大核心优势:

  1. 高密度适配:小体积可集成到手机、平板、车载USB模块等轻薄化设备的PCB中,满足设备小型化趋势;
  2. 自动化贴装:贴片式封装兼容SMT生产线,适合大规模批量生产,降低组装成本;
  3. 空间利用率高:无需额外安装空间,直接焊接在PCB表面,替代传统插件保险丝,优化电路布局。

四、可靠性与环境适应性

该产品针对复杂场景优化了可靠性,核心表现为:

  • 宽温工作范围:支持**-40℃~+85℃** 环境温度,覆盖户外、车载(冬夏极端温度)、工业现场等场景;
  • 自恢复特性:故障排除后自动恢复导通,无需人工更换,减少系统维护次数;
  • 稳定跳断:跳断后阻值稳定在115mΩ以内,无开路或低阻失效,避免二次故障;
  • 环保合规:符合RoHS标准,不含铅、镉等有害物质,适配绿色电子产品设计。

五、典型应用场景

1206L175/24NR因尺寸小、参数适配性强,广泛应用于四大领域:

  1. 消费电子:手机电池保护板、平板充电模块、充电宝过流保护;
  2. 汽车电子:车载USB接口、小功率传感器(胎压监测)、12V车载照明;
  3. 工业控制:小型PLC模块、低压直流电机、传感器节点过流保护;
  4. 通讯设备:路由器/交换机端口、无线AP的电源过流保护。

六、品牌与质量保障

陆特(LUTE)作为专业保护器件品牌,1206L175/24NR经过温度循环、浪涌测试、老化测试等严格可靠性验证,符合工业级质量标准;同时提供稳定供货周期与技术支持,适配客户量产需求。

该产品平衡了小型化、可靠性与成本,是低压中等电流场景过流保护的高性价比选择。

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
