BSMD0603-010-33V 为 BHFUSE(佰宏)系列的一款微型表面贴装自恢复保险元件(PTC resettable fuse)。0603(约1.85×1.05×1.00 mm)封装,适用于电压不超过33V 的低功耗保护场合。器件在正常工作时保持低阻抗以保证最小压降,遇短路或过流时迅速增阻限流,故障解除后自动复位,便于电路重复保护。
该件属聚合物自恢复保险元件,常态下内部导体与聚合物呈低阻状态,允许正常电流通过;当电流超过器件热触发阈值(接近或超过 Itrip)时,器件内部升温使聚合物体积和导电路径发生变化,整体阻值上升至 R1max 量级,从而限制电流,保护下游电路。去除过流后温度回落,聚合物恢复,阻值回到初始态,器件重新导通。动作时间与过流幅度、环境散热条件密切相关,制造商提供的600 ms 为典型值。

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.
