Brightking SMD1210B110TF/16 自恢复保险丝产品概述
一、产品核心定位与功能
SMD1210B110TF/16是台湾君耀（Brightking）推出的贴片式自恢复保险丝，核心作用是为16V及以下低压电路提供过流保护——当电路出现短路、过载等异常过流时，保险丝会快速动作限流，故障排除后自动恢复低阻状态，无需人工更换，兼具保护可靠性与维护便利性。
二、关键性能参数深度解析
产品参数经过严格标定，明确的指标便于电路设计选型，核心参数及意义如下：
参数名称 数值 技术意义 耐压（Vmax） 16V 最大允许工作电压，仅适用于16V及以下低压电路（如5V/12V电源、锂电池系统） 保持电流（Ihold） 1.1A 正常工作下可持续通过的最大电流，电路负载电流需低于1.1A以避免误动作 跳闸电流（Itrip） 2.2A 过流触发阈值（约为保持电流2倍），超过此电流会在规定时间内动作限流 动作时间 300ms 2.2A过流下的响应时间，平衡“快速保护”与“抗脉冲干扰”（避免瞬间浪涌误触发） 初始态阻值（Rmin） 50mΩ 正常工作时的低阻值，功耗小（1.1A时功耗≈60mW），不影响电路效率 跳断后阻值（R1max） 210mΩ 限流状态下仍保持低阻（非完全开路），故障排除后随温度下降自动恢复 工作温度 -40℃~+85℃ 宽温范围，适应工业、车载（辅助电路）、消费电子的高低温环境三、封装与物理特性
产品采用SMD1210贴片封装（英制尺寸，对应公制约3.2mm×2.5mm），实际物理尺寸为：
- 长度：3.43mm
- 宽度：2.8mm
- 高度：1.25mm
小体积设计适合高密度PCB布局（如手机、平板、小型电源模块），支持自动化贴装，生产效率高。
四、典型应用领域
结合参数特性，SMD1210B110TF/16适用于以下场景：
消费电子：
- 手机、平板、智能穿戴的锂电池过流保护（锂电池标称电压3.7V，满电4.2V，16V耐压足够）；
- USB接口过流保护（USB2.0/3.0设备的电流限制需求）。
小型电源模块：
- 5V/12V开关电源的输出端保护（如路由器、机顶盒、LED驱动电源）；
- 电池组（如12V铅酸电池）的充电/放电过流防护。
工业控制：
- 低功耗传感器、小型PLC的辅助电路保护（宽温适应工业环境）。
汽车电子：
- 12V低压辅助电路（如车内USB、小功率传感器）的过流保护（需结合整车认证需求）。
五、产品优势与设计注意事项
核心优势
- 自恢复特性：故障排除后自动恢复，无需更换，降低维护成本；
- 低功耗：初始阻值仅50mΩ，长期工作发热小，可靠性高；
- 宽温适配：-40℃~+85℃覆盖大多数应用场景；
- 参数匹配清晰：Ihold/Itrip比例合理，设计选型无需复杂计算。
设计注意事项
- 耐压限制：严禁用于超过16V的电路，否则会击穿失效；
- 电流匹配：正常负载电流需≤1A（留余量），过流电流需≥2.2A才会动作；
- 动作时间：过流倍数越高，动作时间越短（如3倍Itrip时动作时间约几十ms），需结合电路需求验证；
- 散热考虑：密集封装或高温环境下，需预留散热空间，避免温度过高影响恢复性能。
总结
SMD1210B110TF/16是一款高性价比的低压自恢复保险丝，凭借小封装、宽温、低功耗等特性，覆盖消费电子、小型电源、工业控制等多领域，是电路过流保护的可靠选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
