SMD1206P035TF自恢复保险丝产品概述

一、产品核心定位

SMD1206P035TF是RUILON(瑞隆源)推出的1206封装贴片式自恢复保险丝,基于聚合物正温度系数(PPTC)技术设计,专为低电压、中小功率电路提供过流保护。该器件无需手动更换,故障排除后可自动恢复低阻状态,兼具可靠性与经济性,是消费电子、移动设备等领域的主流保护方案。

二、关键电气性能参数解析

1. 电压与电流特性

  • 最大耐压(Vmax):6V:适配5V及以下主流低压电路(如USB 5V、锂电池3.7V),覆盖大部分移动设备、小型电源的电压需求;
  • 最大耐受电流(Imax):35A:可承受开机浪涌、静电放电等瞬间脉冲电流,避免器件因突发大电流损坏;
  • 保持电流(Ihold):250mA(额定)/350mA(典型):正常工作时,电路电流≤250mA(额定)或350mA(典型)时,器件保持低阻,不影响电路运行;
  • 跳闸电流(Itrip):750mA:当电流超过750mA时,100ms内触发保护,切断过流路径。

2. 电阻与功率特性

  • 初始态最小电阻(Rmin):250mΩ:低阻设计使正常工作压降极小(如250mA电流下仅0.0625V),不影响信号完整性;
  • 跳断后最大电阻(R1max):1.3Ω:过流触发后电阻急剧上升,有效限制故障电流,保护后端IC、电容等敏感元件;
  • 最大功耗(Pd):600mW:正常工作时功耗可控,避免自身过热影响性能。

3. 动作与环境特性

  • 动作时间:100ms:快响应特性可迅速阻断过流,减少电路元件损坏风险;
  • 工作温度:-40℃~+85℃:宽温设计适应低温户外(如北方车载设备)、高温充电(如手机快充)等场景。

三、封装与物理尺寸

该产品采用1206贴片封装,实际尺寸为3.6mm(长)×1.9mm(宽)×0.8mm(高),体积小巧,适配高密度PCB布局(如智能手机、智能手环的内部电路)。贴片式设计兼容自动化贴装工艺,可提升生产效率、降低人工成本。

四、品牌与可靠性优势

RUILON(瑞隆源)作为国内专注过流保护器件的品牌,该产品具备:

  • 参数一致性:成熟PPTC工艺使批量产品离散性小,稳定性可靠;
  • 环保合规:符合RoHS、REACH标准,不含铅、镉等有害物质,适合出口产品;
  • 可靠性验证:经过高低温循环、老化测试,可长期稳定工作。

五、典型应用场景

  1. 移动终端与可穿戴设备:智能手机、智能手环、蓝牙耳机的电池/充电电路保护;
  2. 小型电源:USB充电器、便携充电宝、无线充电器的输出过流保护;
  3. 消费电子:智能音箱、游戏机手柄、电动牙刷的内部电路保护;
  4. 车载辅助电子:车载USB接口、行车记录仪的过流保护(适应-40℃低温)。

六、选型注意事项

  1. 电路正常电流需≤0.8×Ihold(如电路常用电流200mA,选Ihold≥250mA的该产品),避免误触发;
  2. 确认电路最大工作电压≤6V,防止过压损坏;
  3. 若瞬间浪涌电流超过35A,需搭配TVS管等辅助保护。

综上,SMD1206P035TF是低压小功率电路过流保护的高性价比选择,兼具快响应、宽温适应、可重复使用等优势,可满足多场景应用需求。

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
