1210L150/33WR 产品概述

一、产品简介

1210L150/33WR 是 LUTE(陆特) 推出的高可靠性自恢复保险元件(PTC),采用 1210 表面贴装封装,占用空间小,适用于高电压与大电流工作场合。本器件在正常工作时呈低阻抗以保证电源及信号传输,在过流或过温情况下能快速增阻限流并自恢复,广泛用于汽车电子、电源保护与 Type-C 端口的过流/过温保护。

二、主要参数

  • 最大耐压 (Vmax):33 V
  • 最大电流 (Imax):100 A
  • 保持电流 (Ihold):1.5 A
  • 跳闸电流 (Itrip):3 A
  • 消耗功率 (Pd):1 W
  • 初始态阻值 (Rmin):30 mΩ
  • 跳断后阻值 (R1max):130 mΩ
  • 动作时间:500 ms
  • 工作温度:-40 ℃ ~ +85 ℃
  • 尺寸:长度 3.5 mm × 宽度 2.8 mm × 高度 1.3 mm
  • 封装:1210

三、关键特性与优势

  • 小体积 1210 封装,便于高密度 PCB 布局,适合轻薄设备与模块化设计。
  • 高耐压与大电流能力(33V/100A),能够满足 USB Type-C、车载电源总线等苛刻应用。
  • 明确的保持电流与跳闸电流阈值(1.5A / 3A),有助于精确保护设计与过流判定。
  • 跳断后阻值显著上升(≤130 mΩ),有效限制故障电流,降低系统损伤。
  • 宽温工作范围(-40~+85℃),符合汽车级与工业级环境要求。

四、典型应用场景

  • 汽车电子:车载充电器、车内信息娱乐系统、车身控制模块等的短路/过流保护。
  • Type-C / PD 接口:为上下游电源线路提供过流与过温保护,配合控制器实现安全断电。
  • 电源管理:开关电源初级/次级保护、锂电保护线路及分配电路的冗余保护。
  • 工业控制与消费电子:需要小尺寸、高可靠、可复位保护的各种板级应用。

五、选型与使用建议

  • 确认最大工作电压不超过 33V,且在正常工作条件下电流不持续超过 Ihold(1.5A)。
  • 在可能出现短时冲击电流或启动电流的场合,需对比器件 Imax(100A)与脉冲承受能力,必要时在输入端加入限流元件或浪涌抑制器。
  • 考虑功耗 Pd(1W)与环境温度,对 PCB 散热、器件间距进行合理布置,避免长期温升导致触发误动作。
  • 对于精确的保护门限,建议在样品验证中测试实际 Itrip 与回复特性,校准系统检测策略。

六、封装与焊接注意

  • 1210 尺寸小,贴装时注意回流焊温度曲线与焊盘设计,保证良好焊点与热传导。
  • 焊盘与导热铜箔应能支持所需电流,并配合散热过孔或大铜箔以降低温升。

七、可靠性与注意事项

  • 工作温度范围覆盖典型车规与工业级需求,但在高温+高电流工况下需关注寿命与触发漂移。
  • 建议在设计验证阶段进行循环触发、长期老化与环境应力测试,评估 R1max 与自恢复次数的稳定性。

1210L150/33WR 以小封装实现大电流与高耐压的平衡,适用于对体积与可靠性有较高要求的保护场景。在实际应用中,结合系统电流特性与热管理策略可得到最佳保护效果。

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
