SMD1210B150TF/16 自恢复保险丝 产品概述

一、产品简介

SMD1210B150TF/16 是台湾 Brightking(君耀)推出的一款 1210 封装自恢复保险丝(聚合物正温度系数热敏恢复保险器,PPTC)。该器件用于电路过流保护,在超过一定电流后自热并升阻限流,过载解除后可自动恢复低阻态,适合用于便携设备和低压直流电源的短路及过流保护。

二、主要电气与机械参数

  • 额定耐压(Vmax):16 V(适用于低压直流电源系统,如 USB、单节锂电池及 12V 公共母线等)。
  • 最大允许瞬态电流(Imax):100 A(短时浪涌承受能力,非连续工作电流)。
  • 保持电流(Ihold):1.5 A(在指定环境温度下,器件可长期承载而不触发)。
  • 跳闸电流(Itrip):3 A(超过该电流时器件将在规定时间内进入高阻态)。
  • 功耗(Pd):800 mW(器件在正常工作时的功率耗散能力,与升温和热平衡相关)。
  • 初始态阻值(Rmin):30 mΩ(器件出厂未触发时的最小直流电阻,有利于降低压降)。
  • 跳断后阻值(R1max):120 mΩ(触发后稳态高阻值上限,限制过流并保护电路)。
  • 动作时间:300 ms(在接近或达到跳闸电流时的典型动作响应时间)。
  • 工作温度范围:-40 ℃ ~ +85 ℃(适应大多数工业级和消费类环境)。
  • 尺寸(L×W×H):3.43 mm × 2.8 mm × 1.8 mm(标准 1210 SMD 外形,便于自动贴装与回流焊)。

三、产品特点与优势

  • 体积小、低外形高度,适合空间受限的 SMT 设计。
  • 低初始电阻(30 mΩ 起)可有效降低额外功率损耗与压降。
  • 自恢复功能可在短路或过流解除后自动恢复,减少人工更换和维护成本。
  • 能承受高达 100 A 的短时浪涌,适合具有冲击电流的应用场合(仍需注意重复浪涌的寿命影响)。
  • 宽工作温度和工业级可靠性,适配多种工作环境。
  • 标准 1210 封装,兼容常规 SMT 贴装和回流工艺。

四、典型应用

  • USB 电源与数据端口保护(包括充电和外设供电场景)。
  • 便携式设备与移动电源输入保护(单节锂电池、充电管理模块)。
  • 汽车电子子系统(低压附件电源)、车载信息娱乐设备的第二级过流保护(注意符合汽车级资格时需咨询厂商)。
  • 工业控制模块、传感器电源保护、LED 驱动及其他低压直流系统的保护元件。
  • 电源适配器、充电站、保险替换与模块化电源板的防护元件。

五、设计与使用建议

  • 选择器件时应确保 Ihold 大于系统最大持续工作电流;若系统有长期接近 Ihold 的工况,建议留有安全裕度以免出现误触发。
  • 对于频繁的冲击电流或长时间高于 Ihold 的过载,应评估器件的热累积与寿命;尽量避免持续高于 Ihold 的运行。
  • 器件发热时会影响周围元件,布板时应避免邻近对热敏感的元件或将其与散热区域隔离。
  • 自恢复保险丝在触发后阻值会上升至 R1max 量级,对系统供电压降会产生影响;设计时应预留足够的电压裕度。
  • 建议按制造商 Datasheet 的推荐回流焊曲线进行焊接;尽量避免超过推荐峰值温度和超时,防止性能劣化。
  • 不建议将保险丝完全包覆在大量环氧或灌封材料中,因为这会改变散热条件并影响触发特性;若需涂敷,请向厂商确认兼容性。

六、可靠性与测试建议

  • 量产前应对目标应用场景进行典型寿命试验,包括温度循环、潮湿老化、反复触发恢复测试以及冲击/振动测试。
  • 对关键应用建议在不同环境温度下测量 Ihold 与 Itrip,获得实际工作时的动作特性曲线,制定合理的电流保护策略。
  • 评估放置位置对热稳定性的影响,必要时进行热仿真与实测验证。

七、包装与采购注意事项

  • 品牌:Brightking(台湾君耀);封装:1210 SMD;型号:SMD1210B150TF/16(一般表示 1.5A 保持电流、16V 额定电压)。
  • 常见包装形式为卷带(Tape & Reel),适合自动贴片生产,具体数量与最小订购量请向供应商确认。
  • 采购时建议索取最新 Datasheet、可靠性报告及 RoHS/REACH 等合规文件以满足项目验证要求。

总结:SMD1210B150TF/16 以其小巧封装、低初始阻抗与自恢复保护特性,适合多种低压直流系统的过流保护。合理的选型与布板、并配合必要的热与寿命验证,可以在保持系统可靠性的同时降低维护成本。如需具体回流曲线、动作特性曲线(I–T、I–V 曲线)与脚位封装图,请向 Brightking 索取完整技术资料。

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.
