SMD0603-001/60N 是 BORN(伯恩半导体)推出的一款 0603 封装自恢复熔断器(聚合物正温度系数保护器),额定耐压 60V,适用于对微弱电流进行过流保护的表贴场合。器件在过流或短路时能迅速增阻限制电流并在故障解除后自动恢复,为小型化电子产品提供可靠的重复性保护。
该器件为自恢复型 PTC(聚合物)熔断器。在正常工作状态下呈低阻值(典型 Rmin = 15Ω),通过保持电流 Ihold(10mA)时不会发生显著升温或动作;若电流超过设定跳闸值(Itrip≈30mA),器件内部温度上升导致电阻迅速增大(最高可达 R1max = 100Ω),从而限制故障电流并保护下游电路。故障解除并冷却后,电阻逐步回落,器件恢复初始状态,实现可重复使用的保护功能。
简单计算示例:
SMD0603-001/60N 适合对毫安级电流和短路风险有严格保护需求且空间受限的电路。采购时请确认:工作环境温度、系统最大瞬态电流、长期工作电流和焊接工艺是否与器件额定值匹配。如需更高电流等级或不同响应时间的版本,可咨询 BORN(伯恩半导体)提供的完整产品系列与数据手册。
如需更详细的电气特性曲线(温度对 Ihold/Itrip 的影响、能量承受能力、脉冲曲线)与推荐布局,请提供要求,我可以协助解析厂方数据表或给出 PCB 布局建议。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
