RK73B1ETTP104J 产品概述
一、产品简介
RK73B1ETTP104J 为 KOA 出品的厚膜贴片电阻，封装规格为 0402（公制 1.0 mm × 0.5 mm）。标称阻值 100 kΩ，精度 ±5%（J），额定功率 1/10 W（100 mW），额定工作电压 75 V，温度系数（TCR）典型值 ±200 ppm/℃。工作温度范围 -55℃ 至 +155℃，适用于体积受限且对热稳定性有基本要求的电路。
二、主要电气参数
- 电阻类型：厚膜电阻
- 阻值：100 kΩ（标称）
- 精度：±5%（J）
- 额定功率：0.1 W（在基准环境温度下）
- 额定工作电压：75 V（最高持续电压）
- 温度系数：±200 ppm/℃
- 工作温度：-55℃ ～ +155℃
- 封装：0402（1.0 × 0.5 mm）
三、产品特性与优势
- 小型化：0402 封装适合高密度布线和便携设备，节省 PCB 面积。
- 通用性强：100 kΩ/±5% 为常用阻值/精度组合，适用于分压、上拉/下拉、电路偏置等场合。
- 热稳定性：±200 ppm/℃ 的 TCR 在多数通用与工业应用中能保持阻值随温度变化的可控性。
- 宽温工作：-55℃ 至 +155℃ 满足汽车电子、工业控制与户外设备对温度范围的要求（需按具体应用做降额）。
四、典型应用场景
- 数字电路中的上拉/下拉电阻
- 模拟电路的偏置与分压网络
- 便携式与消费电子设备的空间受限电路
- 工业与通讯设备中非精密电阻阵列
（如需用于高精度或高功率场合，应选用更高精度或更大功率等级的产品）
五、安装、焊接及选型建议
- 兼容标准回流焊工艺，建议遵循推荐回流曲线以避免过热引起性能退化。
- 在高温或高功率密度设计中注意功率降额，参考制造商提供的温度-功率降额曲线进行热设计。
- PCB 布局时考虑焊盘与热阻影响，避免在热源附近近距离堆叠多个热耗器件。
- 如需更严格阻值容差或更低 TCR，请选择相应精度或低温漂系列产品。
六、可靠性与环境适应
- 厚膜工艺具有良好的机械强度和抗冲击特性，适合振动与冲击环境。
- 在潮湿或盐雾环境中，应配合适当的涂层或按环境防护等级进行封装处理。
- 建议在严苛环境或关键应用前参考 KOA 的详细寿命与可靠性试验数据。
七、订购信息与标识
产品型号中“104”表示阻值 100 kΩ，“J” 表示 ±5% 精度；完整料号 RK73B1ETTP104J 可用于下单与查询技术资料。采购时请确认包装形式（卷带/盘带）与批次以满足生产需求。
如需更详细的温度-功率降额曲线、机械尺寸图、回流焊工艺建议或环境试验数据，可向 KOA 获取该型号的产品规格书与可靠性报告。

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.
