KTR03EZPF3004（0603）产品概述
一、产品概况
KTR03EZPF3004 为 ROHM（罗姆）出品的贴片厚膜电阻，规格为 0603（约 1.6 mm × 0.8 mm），阻值 3 MΩ，精度 ±1%，额定功率 100 mW，最大工作电压 350 V。温度系数（TCR）为 ±100 ppm/℃，工作温度范围宽（-55℃ ~ +155℃），适用于对高阻值、稳定性及小体积封装有要求的电路设计。
二、主要电气与物理参数
- 电阻类型：厚膜电阻（SMD）
- 阻值：3 MΩ
- 精度：±1%
- 额定功率：100 mW（室温标称）
- 最大工作电压：350 V
- 温度系数：±100 ppm/℃（典型）
- 工作温度：-55℃ 至 +155℃
- 封装：0603（1608公制近似尺寸）
- 品牌：ROHM（罗姆）
- 环保与可靠性：符合常见无铅/RoHS 要求（建议参考厂家数据手册确认）
三、产品特性与优势
- 小尺寸高阻值：0603 封装在有限 PCB 面积内实现 3 MΩ，适合高密度布板与微型化设备。
- 宽温度范围与良好稳定性：±100 ppm/℃ 的 TCR 与 -55℃~+155℃ 的工作温度使其在工业与汽车等恶劣环境中仍能保持性能。
- 高工作电压能力：350 V 的耐压为高阻抗分压、漏电路径和高压偏置网络提供可能。
- 精度较高：±1% 精度适用于需要较好比例精度的阻抗分压或校准电路。
四、典型应用场景
- 高阻抗分压器、偏置网络与输入隔离电路
- 滤波、测量前端的泄放/上拉/下拉电阻
- 精密模拟电路中的参考与校准元件
- 工业控制、汽车电子与通信设备中的高阻阻值需求场合
- 高频或低频传感器前端（需结合寄生电容与环境噪声评估）
五、封装安装与可靠性注意事项
- 贴装工艺：兼容常规无铅回流焊工艺，建议按 ROHM 提供的回流曲线与焊盘推荐进行焊接。
- 功率降额：在高温或散热受限环境中需按厂家功率-温度降额曲线进行计算，避免长期超额载流。
- PCB 布局：高阻值对表面污渍和湿度敏感，建议在关键节点采用保留或防护涂层（如涂覆或清洗）以降低漏电与爬电风险。
- 可靠性测试：推荐参考 IEC/EN 60115 等电阻通用试验标准及 ROHM 的零件规范进行温循环、湿热与机械强度评估。
六、选型建议与替代考虑
在选用时，请确认实际电压、功耗与环境温度是否满足器件额定值；如需更高耐压或更低 TCR，可考虑同系列不同阻值或其他工艺（薄膜、金属膜）产品。为确保产品长期稳定性与一致性，建议索取 ROHM 数据手册与样片进行实际电路测试验证。

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.
