ESR03EZPF2000 产品概述
一、基本参数
ESR03EZPF2000 为 ROHM（罗姆）出品的贴片厚膜电阻，关键参数如下：
- 阻值：200 Ω
- 精度：±1%
- 功率额定：250 mW
- 最高工作电压：150 V
- 温度系数（TCR）：±100 ppm/℃
- 工作温度范围：-55 ℃ ～ +155 ℃
- 封装：0603（尺寸 1608 公制）
- 类型：厚膜贴片电阻
二、主要特点
- 小尺寸（0603）适合集成密度高的表面贴装电路板，节省空间。
- ±1% 精度满足中高精度分压、阻抗匹配和信号处理场景。
- ±100 ppm/℃ 的温度系数在常温范围内提供较为稳定的阻值随温度变化性能，适用于一般温度变化环境。
- 额定功率 250 mW 与 150 V 的最高工作电压使其能在小功率、高阻抗电路中可靠工作。
- 宽工作温度范围（-55 ～ +155 ℃）保证在汽车、工业等苛刻环境中的可靠性（需参考具体应用中的热降额）。
三、典型应用
- 移动设备与消费电子：限流、偏置、阻抗匹配与分压网络。
- 测试与测量电路：精密参考与前端调整（在允许的温漂范围内）。
- 工业与通信设备：信号耦合、滤波网络及通用偏置元件（注意热管理）。
- 汽车电子（非关键安全回路）：需满足更严格的汽车级认证与热降额验证。
四、封装与安装建议
- 建议采用对称焊盘与合理焊膏量，确保焊接强度与热膨胀兼容。0603 封装对焊膏印刷精度和锡膏量较敏感，应优化锡膏模板厚度。
- 焊接工艺：遵循无铅回流规范，避免超温与反复高温循环；推荐按器件供应商或行业标准（如 JEDEC）制定的回流曲线进行。
- 布局注意：避开长期高温热源与高电流走线，确保良好散热路径；大功率密集区域应留有足够间距以降低热影响。
五、使用注意与降额
- 在高环境温度下需进行功率降额以防过热导致阻值漂移或失效，设计时应考虑实际铜面散热和周围元件的热贡献。
- 对于要求极低温漂或高长期稳定性的应用，建议评估使用更低 TCR 或金属膜/薄膜类电阻。
- 长期工作在接近最高工作温度或最大工作电压的条件下，应做可靠性验证（温度循环、湿度应力、负载寿命等）。
六、包装与选型建议
- 该系列通常采用卷装（reel）方式供应，便于自动贴片机贴装。批量采购时请确认包装规格与订货编号以匹配生产需求。
- 选型时应核对阻值、精度、功率与工作电压是否满足电路最大容忍值，并考虑温度升高时的实际功耗与降额需求。
总结：ESR03EZPF2000 是一款适合中等精度与空间受限电路的 0603 厚膜贴片电阻，提供稳定的阻值和较宽的工作温度范围。在电路设计与制造中应重视热管理与焊接工艺，以保证长期可靠性。若需进一步的封装尺寸图、焊盘推荐或可靠性数据，建议参考 ROHM 官方规格书或联系供应商获取完整数据表。

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.
