1206L100/30NR 高分子聚合物自恢复保险丝产品概述

一、产品核心身份与定位

1206L100/30NR是LUTE(陆特)品牌推出的贴片式高分子聚合物自恢复保险丝(PPTC),属于电路过流保护核心器件。其核心价值在于:故障时快速切断电流保护敏感元件,故障消除后自动恢复导通,兼具“一次性保险丝的可靠性”与“可重复使用的便捷性”。型号命名中,“1206”为英制贴片封装,“100”对应常温保持电流1A,“30”对应最大直流耐压30V,精准匹配中低功率电路的防护需求。

二、关键性能参数详解

1. 电气安全与电流阈值

  • 耐压能力:最大直流耐压(Vmax)30V,适配5V/12V/24V低压电路(如消费电子充电、小型电源),无需额外降额即可满足安全标准;
  • 电流匹配:常温下保持电流(Ihold)1A(电路持续工作电流需≤1A,避免误动作),跳闸电流(Itrip)1.8A(过流≥1.8A时触发保护),阈值明确;
  • 脉冲耐受:最大电流(Imax)40A(短时间脉冲),可承受电容充电、开关瞬态等浪涌,提升抗干扰能力。

2. 电阻与功率特性

  • 低阻损耗:初始态最小阻值(Rmin)50mΩ,1A工作电流下压降≤0.05V,对电路效率影响可忽略;
  • 恢复稳定性:跳断后最大阻值(R1max)300mΩ,故障恢复后快速回落低阻,不影响电路正常工作;
  • 功率限额:最大消耗功率(Pd)1.2W,可稳定承受正常工作及短时间过流的功率损耗。

3. 响应与环境适应性

  • 快速动作:典型动作时间300ms,可在敏感元件损坏前切断电流,保护时效高;
  • 宽温范围:工作温度-40℃~+85℃,适配低温户外、高温密闭机箱等场景,无需额外温控。

三、封装与尺寸特性

采用1206贴片封装,实际尺寸为长3.6mm×宽1.9mm×高1.4mm,具备以下优势:

  • 适配自动化SMT贴装,可与其他贴片元件同步焊接,提升生产效率;
  • 体积小巧(约指甲盖1/10),适合高密度PCB设计(如智能手机主板、微型电源),节省布局空间;
  • 耐高温环氧树脂封装,回流焊温度(230℃~260℃)下无变形、剥离风险。

四、典型应用场景

结合参数特性,1206L100/30NR广泛应用于:

  1. 消费电子便携设备:智能手机、蓝牙耳机的电池过充/过放保护,充电接口过流防护;
  2. 小型电源模块:5V/12V微型开关电源、USB PD充电器的输出过流保护;
  3. 工业控制小单元:传感器节点、PLC辅助电路、微型电机驱动的过流防护;
  4. 车载低压附件:车充、车载蓝牙的低温(-40℃)过流保护。

五、品牌与可靠性保障

LUTE(陆特)作为专业过流保护品牌,该产品经过多重可靠性测试:

  • 符合RoHS2.0环保标准,无铅无卤,适配全球市场;
  • 高低温循环测试(-40℃~+85℃,1000次)、老化测试(1A电流1000小时),性能稳定;
  • 批量一致性好,动作阈值偏差≤±10%,避免批量误动作风险。

六、选型与使用注意事项

  1. 电流匹配:持续工作电流≤1A(Ihold),过流保护电流≥1.8A(Itrip);
  2. 电压匹配:电路电压≤30V(Vmax),禁止高压应用;
  3. 功率核算:实际功耗P=I²×R≤1.2W(Pd),避免过热;
  4. 焊接规范:回流焊温度≤260℃,焊接时间≤30秒,避免过焊损坏内部高分子材料。

该产品以高性价比、稳定性能,成为中低功率电路过流保护的优选器件。

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
