RK73H1ETTP5362F 是 KOA 推出的汽车级厚膜芯片电阻,基于 0402(1005 公制)微小封装,阻值为 53.6 kΩ,精度 ±1%,额定功率 0.1W(100 mW),额定工作电压 75V,温度系数 ±100 ppm/℃,工作温度范围 -55℃ 到 +155℃。此型号通过 AEC‑Q200 认证并具备防潮处理,适合对体积、可靠性和温漂有较高要求的汽车及工业电子应用。
RK73H1ETTP5362F 采用厚膜工艺制造,常见特征包括:陶瓷基体上印制厚膜电阻浆料,经烧结、修阻与金属化端形成电气连接。厚膜芯片电阻在体积与成本上具有优势,并通过针对汽车应用的工艺控制与后处理提升了可靠性与防潮性。
作为 AEC‑Q200 通过的汽车级器件,RK73H1ETTP5362F 在高温、振动、温湿循环、机械应力等多项汽车级验证中符合行业标准。防潮处理降低了焊接前储存与装配过程中的吸湿风险,提升了焊接一致性与长期电性能稳定性。
RK73H1ETTP5362F 提供符合工业与汽车供应链惯例的带卷装(tape & reel)包装,适配自动贴片生产线。器件在高湿环境下可能需要遵循吸湿/烘烤管理,建议按厂方提供的存储与烘烤说明进行处理以避免焊接缺陷。
总结:RK73H1ETTP5362F 以 0402 超小尺寸、±1% 精度、±100 ppm/℃ 温漂和 AEC‑Q200 汽车级认证为特点,适合空间受限且需高可靠性的汽车与工业电子设计。合理的 PCB 散热与电压、功率裕量设计将有助于发挥其最佳性能与长期稳定性。若需更详细的电气或焊接曲线、封装图纸与可靠性测试数据,建议查阅 KOA 官方规格书或直接联系供应商技术支持。

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.
