RK73H1ETTP2701F 厚膜固定电阻器产品概述

RK73H1ETTP2701F是日本KOA公司推出的一款小功率精密厚膜固定电阻器,专为高密度、宽温环境下的电子电路设计,核心参数满足通用精密场景的性能需求,广泛应用于便携式设备、工业控制等领域。

一、产品基本信息与命名解析

该电阻属于KOA RK73系列厚膜电阻,型号各部分含义明确:

  • RK73H:系列标识,代表厚膜电阻基础产品线,兼顾成本与性能;
  • 1ETTP:封装与工艺代码,对应402小型封装(英制尺寸1.0mm×0.5mm,公制约1.0×0.5mm),适配高密度PCB布局;
  • 2701:阻值编码(前三位有效数字+倍率),即标称阻值为2.7kΩ(270×10¹Ω);
  • F:精度后缀,代表阻值偏差为±1%,满足精密电路的一致性要求。

二、核心电气性能参数

RK73H1ETTP2701F的电气参数针对小功率精密场景优化,关键指标如下:

  1. 阻值与精度:标称2.7kΩ,精度±1%,确保电路中电压/电流分配的准确性,避免信号失真;
  2. 功率额定值:100mW(1/10W),适合低功耗电路(如传感器调理、单片机外围);
  3. 最大工作电压:75V,是连续工作的安全电压上限,超压可能导致绝缘击穿;
  4. 温度系数(TCR):±100ppm/℃,温度每变化1℃,阻值变化百万分之一百。以工作范围(-55~155℃)计算,阻值最大变化约35Ω,宽温下仍保持稳定。

三、结构与封装特性

该电阻采用厚膜工艺制造,核心结构优势明显:

  • 基底:高稳定性陶瓷材料,耐高温、抗机械冲击;
  • 电阻体:印刷钌基厚膜浆料后高温烧结,形成致密电阻层,阻值稳定性优于碳膜电阻,成本低于薄膜电阻;
  • 封装:402小型化封装,尺寸紧凑(1.0×0.5×0.5mm),可有效缩小产品体积,适配便携式设备的小型化需求。

四、环境适应性与可靠性

RK73H1ETTP2701F具备较强的环境耐受能力:

  1. 宽温范围:-55℃~+155℃,覆盖工业级温度需求,可用于户外设备、汽车辅助系统;
  2. 抗干扰性:厚膜结构抗湿性、抗盐雾性能优于碳膜电阻,符合JIS C 5201、IEC 60115标准;
  3. 长期可靠性:155℃下1000小时寿命测试,阻值变化率<±0.5%,满足长期稳定运行需求。

五、典型应用场景

结合参数特性,该电阻主要应用于:

  1. 便携式电子:智能手机、智能手环、蓝牙耳机,小封装适配紧凑空间;
  2. 工业控制:PLC模块、传感器信号调理,宽温适应工业现场温差;
  3. 消费电子:机顶盒、路由器、智能家居,精密阻值确保信号稳定;
  4. 小型电源:DC-DC转换器、线性稳压器反馈网络,100mW功率与75V电压覆盖常见需求。

六、品牌与品质保障

KOA作为日本老牌元件商,拥有70余年电阻研发经验,产品优势显著:

  • 符合RoHS、REACH环保标准,无铅无卤素封装;
  • 全球供货网络完善,满足批量生产需求;
  • 提供完整技术支持,帮助客户优化电路设计。

总结:RK73H1ETTP2701F是一款性价比高的精密厚膜电阻,兼顾小封装、宽温、高稳定性,适用于多数通用精密电子电路,是工程师选型的可靠选择。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
