SMD1812P150TF/16 产品概述

一、产品简介

SMD1812P150TF/16 是 RUILON(瑞隆源)推出的一款 1812 封装自恢复保险(PTC Resettable Fuse),针对中低压、过流保护场合设计。器件在正常工作时阻值低、功耗小;在过流或短路时能快速增加阻抗,限制电流并在故障消除后自动恢复,适合批量表贴组装的消费类与工业电子设备。

二、主要参数

  • 耐压(Vmax):16 V
  • 最大电流(Imax):35 A(瞬态承受能力)
  • 保持电流(Ihold):1.5 A
  • 跳闸电流(Itrip):3 A
  • 消耗功率(Pd):800 mW
  • 初始态阻值(Rmin):40 mΩ
  • 跳断后阻值(R1max):160 mΩ
  • 动作时间:500 ms(典型,试验条件下)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 尺寸(1812):长度 4.73 mm × 宽度 3.41 mm × 高度 1.1 mm

三、关键特性

  • 低导通电阻:初态 Rmin 仅 40 mΩ,有利于降低待保护回路的压降与发热。
  • 可重复自恢复:故障解除并冷却后阻值恢复,避免一次性熔断元件的更换成本。
  • 快速动作:在设定过流条件下 ~500 ms 触发,有效保护后级器件免受短时大电流伤害。
  • 小型贴片封装:1812 尺寸兼容常见 PCB 组装流程,便于自动化生产。

四、典型应用

  • USB/外围设备电源保护
  • 移动电源与电池管理初级保护
  • 家用与办公电子(路由器、机顶盒、充电器)
  • 工业控制模块的输入保护(在额定温度范围内)

五、选型与使用建议

  • 工作电流应小于 Ihold(1.5 A),并留有裕量以避免环境升温导致误动作。
  • 对于频繁短时浪涌,确认器件 Imax 与 PCB 散热是否足够;必要时采用并联或选用更高规格器件,但并联自恢复保险需谨慎,可能造成不均流。
  • 布局时保证周围有散热通道,避免长期高温运行;遵循厂商的回流焊工艺建议以免影响特性。
  • 在高安全等级或关键负载场合,可与热熔断器或限流电路结合使用,形成冗余保护。

六、封装与可靠性注意事项

1812 尺寸适合自动贴装与回流焊接,但应避免超温剥离与过度机械应力;存储与使用环境避免长期高湿高温,典型工作温度为 -40 ~ +85 ℃。器件经过多次触发后可能表现出阻值漂移,建议在设计中保留维护与更换策略。

SMD1812P150TF/16 以其低阻、可复位与小体积优势,适合对成本与可维护性有要求的电路保护应用。根据实际工况选型与合理 PCB 热管理,可获得长期稳定的保护效果。

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
