RK73H2ATTD3301F是日本KOA公司推出的0805封装工业级厚膜贴片电阻,主打“精准阻值+宽温稳定+中小功率适配”,可满足消费电子、工业控制、汽车电子等领域的通用电路需求。其核心参数均符合KOA官方标准,关键指标如下:
核心参数 具体值 说明 阻值 3.3kΩ(代码3301) 330×10¹Ω,标识清晰易识别 精度 ±1% 高于常规±5%电阻,适合分压/限流精准需求 额定功率 250mW 0805封装常用功率等级,适配中小功率电路 工作电压 150V(最大连续) 峰值电压需控制在200V内(参考安全规范) 温度系数(TC) ±100ppm/℃ 100℃温差下阻值变化≤±0.1% 工作温度范围 -55℃~+155℃ 覆盖工业/汽车电子常见温区该电阻采用0805英寸封装(公制对应2012,即2.0mm×1.2mm),兼容主流SMT贴装设备,物理特性如下:
在25℃、0.5W以下功率下,阻值年漂移≤±0.05%(KOA厚膜工艺保障),批量产品一致性达±0.1%,无需额外校准即可满足电源模组、传感器信号链等场景的精准要求。
±100ppm/℃的TC值,意味着-55℃~155℃温差下,阻值变化仅±2.1%(3300Ω×210℃×100ppm=±69.3Ω),可稳定适配极端温度环境(如汽车发动机舱、工业现场)。
该电阻通过多项国际标准测试,可靠性表现优异:
结合参数特性,该电阻广泛应用于以下领域:
RK73H2ATTD3301F凭借KOA的厚膜工艺优势,在精准度、稳定性与成本控制间实现平衡,是中小功率电路的高性价比选择。

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.
