BSMD0603-003-30V 是佰宏(BHFUSE)推出的一款 0603 封装自恢复保险丝(PTC resettable fuse),适用于小型表面贴装电路的过流保护。器件体积小(1.85 mm × 1.05 mm × 1.0 mm),在过流或短路时能快速升阻限流,消除故障后自动恢复到低阻状态,便于重复使用,适合便携设备与低压电源保护场景。
该型号适用于工业级温度范围(-40 ℃ ~ +85 ℃),适合大多数民用与工业应用场景。常见为卷带(Tape & Reel)贴片包装,便于 SMT 自动化装配。批量采购和高可靠性需求时,建议向厂家索取完整的可靠性试验报告与焊接工艺说明,以便通过系统级验证。
总结:BSMD0603-003-30V 提供了小型化、可重复恢复的过流保护方案,适合对体积敏感、工作电流较小但需要可靠保护的电子产品。选用时应以 Ihold、Itrip 与电路热环境为准,必要时在 PCB 实际条件下做验证测试。

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.
