RK73H1JTTD1000F厚膜贴片电阻产品概述
一、产品基本信息
RK73H1JTTD1000F是KOA株式会社推出的经典厚膜贴片电阻，属于RK73系列小型化电阻产品。该电阻采用0603封装（英制） ，对应公制尺寸1608，核心参数为：标称阻值100Ω、精度±1%、额定功率125mW，专为高密度、低功耗电子电路设计，适配多场景稳定使用需求。
二、核心技术参数
RK73H1JTTD1000F的关键参数经过严格校准，满足不同环境下的性能要求：
- 阻值与精度：标称阻值100Ω，精度等级±1%，可避免因阻值偏差导致的信号失真或功率损耗异常，适配普通精密电路的阻值匹配；
- 功率与电压：25℃环境下额定功率125mW，最大工作电压75V（经计算：75V×75V/100Ω=56.25mW≤125mW，符合功率额定值）；
- 温度系数：±100ppm/℃，即温度每变化1℃，阻值变化±0.01%，宽温范围内保持阻值稳定性；
- 工作温度范围：-55℃至+155℃，覆盖工业级、汽车级等高低温场景的使用需求。
三、封装与尺寸规格
该电阻采用0603贴片封装，具体尺寸（公制）为：
- 长度：1.6mm±0.15mm
- 宽度：0.8mm±0.15mm
- 厚度：0.45mm±0.05mm
- 焊盘间距：约1.2mm
小尺寸设计适配高密度PCB布局，支持自动化贴装生产，有效降低电路空间占用，适合便携式设备、小型模块等对尺寸敏感的应用。
四、典型应用场景
RK73H1JTTD1000F凭借小封装、宽温工作及稳定性能，适用于以下场景：
- 消费电子：智能手机、平板电脑、智能穿戴设备的电源滤波、信号分压电路；
- 工业控制：小型传感器（温度、压力传感器）的信号调理电路，PLC模块辅助电路；
- 汽车电子：车载低功耗模块（胎压监测、座椅传感器）的辅助电路（工作温度覆盖汽车舱内高低温）；
- 通信设备：小型基站、路由器的信号处理电路，无线模块的阻抗匹配。
五、性能优势

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.
