RK73H1JTTD1003F 厚膜贴片电阻产品概述

RK73H1JTTD1003F是日本KOA公司推出的一款常规功率厚膜贴片电阻,针对高密度PCB设计优化,具备稳定的电气性能与宽温适应性,广泛适用于消费电子、工业控制等多领域电路。

一、基本产品标识与定位

该型号为KOA厚膜电阻系列的典型产品,型号编码隐含核心参数:

  • 1003 代表标称阻值为100kΩ(100×10³Ω);
  • 精度等级为±1%(型号中通过特定代码标识);
  • 额定功率100mW(即1/10W),匹配0603封装的功率承载能力。

产品定位为中精度、常规功率贴片电阻,平衡了成本与性能,适合多数非超高精度需求的电路设计,无需额外校准即可适配常规应用。

二、核心电气性能参数

1. 阻值与精度

标称阻值100kΩ,精度±1%,实际阻值范围为99kΩ~101kΩ。此精度可满足信号调理、分压、限流等多数电路的阻值控制需求,避免因阻值偏差导致的电路性能波动。

2. 功率与电压额定值

  • 额定功率:100mW(1/10W),是0603封装贴片电阻的主流功率等级,可稳定承载电路中的常规功率损耗;
  • 额定工作电压:75V(直流/交流有效值),为电阻两端允许施加的最大电压,需注意电路设计中不可超过此限值,避免击穿或性能劣化。

3. 温度系数(TCR)

温度系数为±100ppm/℃,表示环境温度每变化1℃,阻值变化量为标称值的±100×10⁻⁶。以100kΩ为例,温度变化±100℃时,阻值变化仅±1kΩ,此稳定性可覆盖多数宽温应用场景。

三、机械与封装特性

1. 封装规格

采用0603封装(英制:0.06″×0.03″;公制1608:1.6mm×0.8mm),体积小巧,适合高密度PCB布局,可有效节省电路板空间,适配手机、智能穿戴等小型化电子设备需求。

2. 工艺与结构

基于厚膜电阻工艺制造:在高纯度氧化铝陶瓷基底上印刷电阻浆料并高温烧结,形成致密稳定的电阻膜层;端电极采用“银浆+镍+锡镀层”三层结构,兼顾焊接可靠性与抗氧化性。

3. 焊接兼容性

端电极设计兼容回流焊、波峰焊等主流贴片工艺,焊接后拉脱力符合行业标准(≥10N),无铅设计符合RoHS 2.0环保要求。

四、环境适应性

1. 工作温度范围

支持**-55℃+155℃**的宽温工作,覆盖工业级温度范围(常规工业级为-40℃+125℃),且在极端温度下仍能保持电气性能稳定,适合户外设备、汽车电子(如引擎舱周边辅助电路)等场景。

2. 长期环境稳定性

厚膜电阻结构对湿度、灰尘等环境因素具有耐受性:长期暴露于湿度30%~85%的常规环境下,阻值变化率≤0.5%(KOA产品标准);1000小时高温老化(155℃)后,阻值漂移≤0.2%,保证电路长期可靠性。

五、典型应用场景

该电阻的参数特性使其适用于以下领域:

  1. 消费电子:手机、平板、智能手环的传感器偏置电路、LED驱动限流;
  2. 工业控制:PLC、传感器接口的分压/限流电路,适配工业现场宽温环境;
  3. 汽车电子:车载仪表盘背光、胎压监测系统的信号处理电路;
  4. 通信设备:路由器、交换机的偏置电路、滤波网络;
  5. 小型医疗设备:便携式血糖仪、血压计的信号放大与调理电路。

六、品牌与可靠性优势

KOA作为日本老牌电子元器件制造商,拥有数十年电阻生产经验,RK73H1JTTD1003F具备以下优势:

  • 一致性优异:量产产品的阻值、功率等参数离散性小,减少电路调试工作量;
  • 环保合规:符合RoHS 2.0、REACH等国际标准,满足出口产品要求;
  • 供货稳定:作为常规型号,KOA具备充足产能与库存,支持批量采购需求;
  • 售后保障:提供标准产品质保,针对批量应用可提供定制化技术支持。

总结:RK73H1JTTD1003F是一款性价比突出的厚膜贴片电阻,以1%精度、100mW功率、宽温适应性为核心优势,适配多领域常规电路设计,是电子工程师平衡成本与性能的可靠选择。

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.
