SMD0603-005/48N — BORN(伯恩) 0603 自恢复保险丝产品概述
一、产品简介
SMD0603-005/48N 是 BORN（伯恩半导体）出品的一款 0603 封装自恢复保险丝（PTC 聚合物电流保护元件）。该器件设计用于低电压、低电流的过流保护场景，在过载或短路时能快速限流并在故障解除后自动恢复，便于SMT量产与小型化电路保护需求。
二、主要技术参数
- 额定耐压：Vmax = 48V
- 最大通过电流：Imax = 40A（瞬态或短时通过能力）
- 保持电流：Ihold = 50mA（正常工作不动作的最大稳态电流）
- 跳闸电流：Itrip = 150mA（在规定时间内动作的电流）
- 耗散功率：Pd = 500mW
- 初始态阻值：Rmin = 3.5Ω
- 跳断后阻值：R1max = 40Ω（动作后限流电阻）
- 动作时间：约 1s（在 Itrip 条件下的典型动作时间）
- 工作温度：-40℃ ~ +85℃
- 外形尺寸（典型）：长 1.85mm × 宽 1.05mm × 高 0.8mm（0603 封装）
三、产品特性与优势
- 小型化：0603 封装，适合高密度 PCB 布局与便携设备。
- 自恢复：故障解除后无需更换，降低维护成本。
- 快速响应：在150mA左右短时间过流时能在约1秒内动作，保护下游电路。
- 宽工作温度范围，适应多种应用环境。
- 低待机阻值，保证正常工作时电压降小。
四、典型应用场景
- 移动设备外围保护（例如传感器、电源开关线）
- 小型通信设备、模块化接口的过流保护
- 工业控制低压回路、板级保护
- USB外围、I/O 口保护（需确认电流规格匹配）
注：不建议在高功率连续负载中长期使用，适用于短路或短时过流保护。
五、设计与选型建议
- 确认电路的正常工作电流低于 Ihold，避免误动作。
- 对励磁或间歇性大电流脉冲，需评估 Imax 与 Pd 能否承受；若脉冲能量大，考虑并联或选用更大规格器件。
- 布局时保证良好散热路径与焊盘尺寸，避免器件超温影响动作特性。
- 在高干扰或高温环境下需适当留出裕量，参考厂方温度-电流特性曲线进行降额设计。
六、贴装与可靠性注意
- 适用常规 SMT 回流焊工艺，推荐按制造商给出的回流温度曲线执行，避免过冲导致性能退化。
- 焊盘设计遵循 0603 封装规范，避免过量机械应力和焊接翘曲。
- 储存与使用时避免长时间潮湿环境，必要时进行防潮处理。
七、包装与订购信息
- 品牌：BORN（伯恩半导体）
- 封装：0603 SMD
- 描述分类：未分类（按供应商标签或数据表确认详细型号）
- 在采购前建议联系供应商获取最新数据手册、典型曲线与样品验证数据，以确保在具体应用中的可靠性与一致性。
以上为 SMD0603-005/48N 的概述与实用指导，若需完整的 I-V 曲线、温度特性或回流焊工艺参数，可提供更详细的数据表或协助评估到板级应用方案。

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.
