RK73H2BTTD1003F 厚膜电阻产品概述

RK73H2BTTD1003F是KOA公司推出的一款1206封装厚膜贴片电阻,针对中小功率、中高压、中等精度的电子电路需求设计,具备宽温度范围、高稳定性等核心优势,广泛应用于工业控制、通信、消费电子等领域。

一、产品核心参数概览

该电阻的关键参数均围绕工业级应用需求优化,具体如下:

参数类别 具体规格 关键备注 电阻类型 厚膜贴片电阻 陶瓷基厚膜印刷工艺 标称阻值 100kΩ(编码1003) 阻值精度±1% 功率额定值 250mW(1/4W) 25℃常温下额定功率 电压额定值 200V 直流/交流峰值电压上限 温度系数(TCR) ±100ppm/℃ 0-60℃范围内典型值 工作温度范围 -55℃ ~ +155℃ 工业级宽温耐受性 封装尺寸 1206(公制3216) 3.2×1.6mm贴片封装,适配回流焊 品牌 KOA 日本原厂工艺,可靠性认证

二、产品关键特性解析

1. 宽温度适应性

工作温度覆盖**-55℃至+155℃**,远超普通民用级电阻(-40~85℃),可稳定工作于高温工业环境(如电机控制柜、汽车发动机舱周边)或低温户外场景(如北方户外通信设备),无需额外温度补偿电路。

2. 中高压耐受能力

200V电压额定值避免了低电压电阻的击穿风险,适用于电源分压、高压信号滤波、射频匹配等中高压电路,满足工业控制、通信设备的信号传输需求。

3. 稳定的温漂特性

±100ppm/℃的温度系数意味着:当环境温度变化100℃时,阻值变化不超过0.01%,在温度波动较大的工业场景中仍能保持电路参数稳定,降低系统调试难度。

4. 高可靠性与一致性

KOA厚膜工艺确保批量产品阻值偏差控制严格(符合±1%精度要求),通过AEC-Q200等可靠性测试(车载级标准),可应对长期高温、湿度循环等严苛环境,适合量产应用。

5. 小型化贴片封装

1206封装体积小,便于PCB高密度布局,适配现代电子设备小型化、轻量化的设计趋势,同时兼容回流焊、波峰焊等主流贴片工艺。

三、典型应用场景

1. 工业控制电路

  • PLC输入输出接口的限流/分压电阻;
  • 电机驱动电路的电流采样电阻;
  • 传感器信号调理(如压力、温度传感器的分压网络),利用宽温范围和1%精度满足工业环境稳定需求。

2. 通信设备

  • 基站射频电路的阻抗匹配网络;
  • 光模块偏置电路的限流电阻;
  • 交换机信号滤波电路,200V电压额定适配中高压信号传输。

3. 消费电子

  • 智能家居传感器接口(如温湿度传感器分压);
  • 电源适配器辅助电路(如待机电源限流);
  • 小型家电控制板的信号调理,1206封装适配小型化设计。

4. 汽车电子

  • 车载中控系统信号调理电路;
  • 车身控制模块(BCM)输入电路,宽温范围满足汽车舱内外温度变化。

四、选型与使用注意事项

1. 功率降额设计

高温环境下需降额使用:参考KOA官方曲线,125℃以上降额50%,155℃时建议功率不超过175mW(额定值的70%),避免电阻过热失效。

2. 电压限制

电路峰值电压不得超过200V,若应用场景电压更高(如300V),需串联电阻或更换更高电压额定值的型号(如RK73H系列250V版本)。

3. 焊接工艺要求

回流焊需遵循KOA推荐曲线:峰值温度240~250℃,持续时间≤10秒;波峰焊温度≤260℃,避免焊接温度过高损坏电阻基体。

4. 精度与温漂考量

若电路精度要求>1%(如精密仪器),需选择0.1%精度型号;若温度变化>100℃,建议增加温度补偿电路(如NTC热敏电阻并联)。

5. 储存条件

未使用电阻应储存在**-40~85℃、相对湿度≤85%** 的环境中,避免暴露于潮湿、腐蚀性气体(如硫化物),储存期建议不超过12个月。

五、品牌与可靠性说明

KOA作为日本老牌电子元器件厂商,拥有50+年厚膜电阻研发制造经验,产品符合RoHS、REACH等环保指令,批量一致性优异(同批次阻值偏差≤0.5%),可降低客户选型风险,适合对可靠性要求较高的工业、汽车领域。

RK73H2BTTD1003F凭借平衡的性能参数(精度、功率、电压、温度范围)和KOA的可靠性保障,成为中小功率、中高压电路的高性价比选型,可广泛适配多种应用场景的设计需求。

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.
