RK73H2BTTD5601F 厚膜贴片电阻产品概述
一、产品基本定位与品牌依托
RK73H2BTTD5601F是日本KOA公司推出的通用型中小功率厚膜贴片电阻，定位于兼顾成本控制与性能可靠性的电路核心元件，广泛适配工业、消费电子、通信等多领域应用。KOA作为全球被动元件领域的知名品牌，其厚膜电阻产品以稳定的工艺一致性、严格的质量管控著称，该型号延续了品牌的核心优势，是替代同类通用贴片电阻的可靠选择。
二、关键性能参数全解析
该型号的核心参数直接决定了应用边界，具体如下：
- 阻值与精度：标称阻值5.6kΩ（代码标识“5601”），精度±1%（F级），满足多数需要中等精度的电路需求（如信号分压、基准电压调整、MCU外围电路）；
- 功率与电压：额定功率250mW，最大工作电压200V，覆盖常见小功率电路（如LED限流、电源滤波）的功率需求，避免过载风险；
- 温度特性：温度系数±100ppm/℃，工作温度范围-55℃~+155℃，宽温环境下阻值变化可控（如155℃时与25℃基准相比，阻值变化约1.3%，仍在精度范围内）；
- 工艺类型：采用厚膜工艺，相比薄膜电阻成本更低，相比线绕电阻体积更小，适合批量SMT生产。
三、封装与物理特性
该电阻采用1206封装（公制对应3216，尺寸3.2mm×1.6mm），是贴片电阻中最常用的封装之一，具有以下特点：
- 体积紧凑：适配高密度PCB设计，满足设备小型化需求（如智能手机、小型工业控制器）；
- 贴片式结构：支持自动贴装（SMT），大幅提升生产效率，降低人工成本；
- 陶瓷基底：采用厚膜陶瓷工艺，抗热冲击能力强，长期使用不易出现阻值漂移。
四、典型应用场景
结合参数特性，该型号主要适用于以下场景：
- 工业控制电路：PLC输入输出模块、传感器信号调理电路（宽温-55~155℃适配工业现场高低温波动）；
- 消费电子设备：智能手机/平板的电源管理电路、LED背光驱动电路（250mW功率满足小功率负载）；
- 通信设备：路由器、交换机的信号滤波/分压电路（±1%精度保证信号传输准确性）；
- 车载辅助电路：汽车仪表盘背光、中控小功率控制电路（宽温范围适配车载-40℃~85℃的温度要求）。
五、可靠性与环境适应性
作为厚膜贴片电阻，RK73H2BTTD5601F的可靠性体现在：
- 抗振动/冲击：贴片封装与PCB贴合紧密，可承受10G以上振动（符合多数电子设备振动标准）；
- 长期稳定性：厚膜工艺避免了线绕电阻的氧化问题，陶瓷基底耐高温老化，使用寿命可达10万小时以上；
- 环保兼容性：符合RoHS标准，无铅无镉，适配全球市场的环保要求。
总结
RK73H2BTTD5601F以“高性价比+宽温适应性+中等精度”为核心优势，是中小功率电路中替代普通碳膜电阻的理想选择，尤其适合对成本敏感但需要一定可靠性的批量应用场景。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
