RK73H2BTTD1001F 厚膜电阻产品概述

RK73H2BTTD1001F是日本KOA公司推出的通用型厚膜片式电阻,专为低功率、高精度电路设计,兼顾紧凑尺寸与宽环境适应性,广泛覆盖消费电子、工业控制等领域的主流应用需求。

一、核心参数与产品定位

该电阻的核心技术参数明确适配中小信号电路的性能要求,关键参数如下:

  • 标称阻值:1kΩ(代码标识“1001”,符合E96系列电阻编码规则);
  • 精度等级:±1%,满足非精密仪器的高精度场景需求;
  • 功率规格:250mW(1/4W),适配低功耗电路的功率预算;
  • 工作电压:最大200V(为电阻两端允许施加的峰值电压,与功率参数独立);
  • 温度系数(TCR):±100ppm/℃,阻值随温度变化的稳定性较好;
  • 工作温度范围:-55℃至+155℃,覆盖宽温环境需求。

产品定位为通用型厚膜贴片电阻,兼顾成本与性能,适合量产化、高密度PCB设计场景。

二、封装与尺寸规格

采用1206英寸封装(对应公制3216,即长3.2mm、宽1.6mm),具体尺寸符合行业标准:

  • 长度:3.2mm±0.2mm;
  • 宽度:1.6mm±0.15mm;
  • 厚度:0.5mm±0.1mm(含电极)。

1206封装是贴片电阻的主流规格之一,兼容自动化贴装工艺(SMT),可适配多数PCB的布线密度,尤其适合需要紧凑布局的消费电子、小型工业设备。

三、电气性能特性

作为厚膜电阻,RK73H2BTTD1001F具备典型的厚膜工艺优势:

  1. 阻值稳定性:丝网印刷+烧结的厚膜工艺使电阻膜层与陶瓷基底结合牢固,长期使用阻值漂移小;
  2. 功率与电压适配性:250mW功率可满足常见小信号电路的限流、分压需求(如5V电源下,最大允许电流约20mA,符合多数传感器、信号调理电路的电流范围);200V工作电压则支持高压小电流场景(如AC/DC辅助电路);
  3. 温度特性:±100ppm/℃的TCR意味着,在工作温度范围内(-55~155℃,温差210℃),阻值最大变化约±2.1%,能保证宽温环境下的电路性能一致性。

四、环境适应性

该电阻的环境耐受能力突出,适合复杂工况:

  • 温度耐受:-55℃至+155℃的工作范围,覆盖工业级(-40~125℃)及部分户外高温场景(如太阳能逆变器、车载小功率模块);
  • 耐候性:厚膜结构抗湿性、抗腐蚀性优于部分薄膜电阻,可应对潮湿、轻微腐蚀性环境(如户外通信设备、工业现场);
  • 机械稳定性:陶瓷基底强度高,贴装后抗振动、抗冲击性能良好,适合移动设备(如手持终端、车载仪表盘)。

五、典型应用场景

RK73H2BTTD1001F的性能匹配多领域需求,常见应用包括:

  1. 消费电子:手机、平板的电源滤波电路、信号分压网络;
  2. 工业控制:PLC(可编程逻辑控制器)的输入输出接口、传感器信号调理电路;
  3. 通信设备:基站辅助电源、路由器的电压转换电路;
  4. 照明领域:LED驱动电路的限流电阻、调光电路分压;
  5. 汽车电子(边缘场景):车载USB充电电路、仪表盘背光驱动。

六、品牌与可靠性优势

KOA作为全球知名电子元器件厂商,其产品具备以下可靠性优势:

  • 工艺成熟:厚膜电阻生产工艺经过多年优化,批次间阻值一致性高,偏差控制严格;
  • 环保合规:符合RoHS 2.0、REACH等国际环保标准,不含铅、镉等有害物质;
  • 质量认证:产品通过ISO 9001、IATF 16949等质量体系认证,故障率低,适合量产需求。

综上,RK73H2BTTD1001F以其高精度、宽温适应性、紧凑尺寸及可靠性能,成为低功率电路设计的常用选择,可满足多数消费电子与工业场景的电阻需求。

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
