1206L035/48NR 自恢复过流保护器件产品概述

1206L035/48NR是陆特(LUTE)推出的一款贴片式自恢复过流保护器件,主打小型化、高可靠性、快速响应,适配1206封装的自动化贴装需求,广泛用于消费电子、工业控制、智能穿戴等领域的过流/过温保护场景,可替代一次性保险丝实现重复保护,降低维护成本。

一、产品核心定位与价值

作为一款低压小电流型自恢复保险丝(PPTC),1206L035/48NR的核心价值在于:

  1. 小体积适配高密度电路:1206封装+3.6×1.9×1mm尺寸,节省PCB空间,适合手机、蓝牙耳机等便携设备的紧凑布局;
  2. 可重复保护替代一次性方案:过流故障排除后自动恢复,无需手动更换,提升设备可靠性;
  3. 低损耗不影响电路性能:初始态低阻值设计,减少正常工作时的功率损耗,避免干扰信号传输。

二、关键参数与性能解析

该产品的核心参数均基于25℃标准环境测试,具体性能如下:

1. 电气保护参数

  • 保持电流(Ihold):350mA:25℃下,器件持续导通不动作的最大电流,需匹配电路正常工作的最大电流(如电路持续电流≤300mA时可稳定工作);
  • 跳闸电流(Itrip):750mA:25℃下,过流触发动作的最小电流,确保电路过流时快速切断;
  • 动作时间:100ms:过流达到跳闸电流时,100ms内可从低阻态切换至高阻态,有效保护后端敏感元件;
  • 耐压(Vmax):48V:最大工作电压,适配低压电路(如5V/12V/24V系统);
  • 最大峰值电流(Imax):40A:故障瞬间可承受的峰值电流,避免器件被大电流击穿。

2. 电阻与功耗特性

  • 初始态阻值(Rmin):250mΩ:正常工作时的低阻值,仅产生微小压降(如350mA电流下,压降约87.5mV),不影响电路效率;
  • 跳断后阻值(R1max):1.5Ω:过流动作后进入高阻态,有效阻断电流,保护负载;
  • 消耗功率(Pd):800mW:正常工作时的最大功耗,符合低功耗设计要求。

三、封装与尺寸特性

1206L035/48NR采用1206贴片封装(英制尺寸规范),实际物理尺寸为:

  • 长度:3.6mm
  • 宽度:1.9mm
  • 高度:1mm

该封装适配SMT自动贴装生产线,焊接兼容性好,可与其他贴片元件同步组装,适合批量生产。小尺寸特性使其可嵌入手机电池保护板、智能手表主板等紧凑空间,满足便携设备的小型化需求。

四、典型适用场景

结合参数特性,该产品主要应用于以下场景:

1. 消费电子领域

  • 便携设备电池保护:手机、平板、蓝牙耳机的电池过充/过放保护电路,匹配3.7V/4.2V电池系统;
  • 充电电路保护:USB充电器、无线充的过流保护,避免充电线短路导致设备损坏。

2. 智能穿戴与智能家居

  • 智能手表/手环:主板过流保护,适配-40℃~+85℃的宽温环境;
  • 智能家居传感器:温湿度传感器、门窗传感器的电源保护,防止短路故障。

3. 工业控制与通信

  • 小型工业模块:PLC辅助电路、传感器节点的过流保护;
  • 通信基站小模块:光纤收发器、信号放大器的低压保护电路。

五、可靠性与环境适应性

  1. 宽温工作范围:-40℃~+85℃,满足工业级环境要求(如低温地区户外设备、高温车间设备);
  2. 可重复动作:过流故障排除后(温度降低至恢复阈值),器件自动从高阻态回到低阻态,无需手动重置;
  3. 环保与合规:符合RoHS无铅环保要求,适配全球市场准入;
  4. 一致性与稳定性:陆特(LUTE)作为专业器件厂商,产品批量一致性好,长期工作可靠性高。

六、选型与使用注意事项

1. 选型参考

  • 需确保电路正常持续电流≤Ihold(350mA),避免器件误动作;
  • 电路最大工作电压≤Vmax(48V),防止耐压不足击穿;
  • 故障瞬间峰值电流≤Imax(40A),避免器件损坏。

2. 使用注意

  • 焊接工艺:SMT回流焊温度≤260℃,焊接时间≤10s(避免高温损伤器件);
  • 散热设计:避免靠近发热元件(如功率芯片),防止环境温度过高导致Ihold降低;
  • PCB布局:器件周围预留适当空间,便于散热;若需并联使用,需确保电流均匀分配。

1206L035/48NR凭借小型化、快速响应、可重复保护等特性,成为低压小电流电路过流保护的优选方案,适配多领域的紧凑化设计需求。

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.
