RK73H2ATTD1001F是日本KOA公司推出的通用型厚膜贴片电阻,采用0805(英制)封装,核心参数聚焦1kΩ阻值、±1%精度、250mW额定功率,适配工业控制、消费电子、汽车电子等多领域需求,兼具成本优势与性能稳定性。
该型号属于KOA厚膜贴片电阻系列的主流产品,定位为中精度、中小功率、宽温适用的通用无源器件。型号编码“1001”遵循国际电阻编码规范:前三位“100”为有效数字,第四位“1”为倍率(10¹),即100×10¹=1000Ω(1kΩ),清晰对应标称阻值。
采用0805贴片封装(公制对应2012,尺寸2.0mm×1.2mm×0.5mm),适配SMT自动化生产,兼容回流焊、波峰焊工艺。端电极采用“镍底层+锡镀层”结构,保证焊接强度与长期可靠性,避免虚焊、脱焊。厚膜工艺(丝网印刷+烧结)赋予其成本优势,兼顾功率密度与稳定性,区别于薄膜电阻的高精度高成本路线。
KOA作为日本百年无源器件厂商,厚膜电阻工艺成熟,品控严格。该型号通过ISO 9001、IATF 16949认证,产品一致性获华为、三星、西门子等客户验证,广泛应用于全球终端产品。
总结:RK73H2ATTD1001F是性价比突出的通用厚膜电阻,平衡精度、功率、宽温与成本,是多数电子设备“够用且可靠”的优选方案。

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.
