RK73B1ETTP103J 是 KOA Speer Electronics 推出的 RK73B 系列微型厚膜片式电阻,标称阻值 10 kΩ,公差 ±5%,功率额定 0.1W(1/10W),封装 0402(1005 公制)。该型号为汽车级 AEC-Q200 认证、具防潮特性的活动件,适合在苛刻环境下长期稳定工作。
该件采用厚膜工艺,具备良好的成本效益和尺寸适配性。TCR ±200 ppm/°C 表明在温度变化下阻值稳定性属于中等水平,适用于一般用途电路;对高精度测量或温漂敏感的应用建议选用更低 TCR 的电阻(如金属膜)。厚膜结构相对于薄膜在噪声与长期漂移方面略逊,但在耐环境性与机械强度上表现可靠。
作为 AEC-Q200 认证零件,RK73B 系列通过了汽车级温循环、高低温存储、湿热、机械冲击等严格可靠性测试,适合车规级应用的长期稳定性要求。
总结:RK73B1ETTP103J 以其 0402 超小体积、车规认证与防潮处理,适用于对空间与可靠性有严格要求的应用场景。针对具体温度、功率与精度需求,建议在设计阶段结合制造商数据表与热降额曲线进行校核。

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.
