RK73H2ATTD1802F是KOA针对中小功率电路设计的0805封装厚膜电阻,核心参数完全匹配工业级常规需求,具体如下:
±1%精度可满足消费电子(如手机音频滤波)、工业控制(如PLC信号衰减)的核心需求;±100ppm/℃的TCR在**-55℃~155℃全温区**内,最大阻值漂移仅3.78Ω(温度差210℃),远低于±1%的精度容限(180Ω),长期使用阻值稳定性可靠。
250mW额定功率针对低功耗电路设计,避免功率冗余导致的体积浪费;150V工作电压可支撑12V~48V电源系统的分压监测(如智能家居设备的电源反馈),无需额外并联电阻降额。
采用氧化铝陶瓷基片+厚膜电阻浆料烧结工艺,抗机械应力、抗冲击性能优于薄膜电阻;0805封装适合SMT批量贴装,焊接后抗振动性能满足IEC 60068-2-6标准(10~2000Hz振动测试),适合车载、工业等振动场景。
RK73H2ATTD1802F以平衡的性能、紧凑封装和高性价比,成为消费电子、工业控制、汽车辅助电子等领域的主流选择,尤其适合对精度、稳定性有常规要求且需高密度布局的电路设计。

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.
