ROHM ESR18EZPF1101 厚膜贴片电阻产品概述
ESR18EZPF1101是罗姆（ROHM）推出的1206封装厚膜贴片电阻，针对中等功率、宽温区应用场景优化设计，兼具高精度、高稳定性与成本优势，广泛适配工业控制、消费电子等领域的电路需求。
一、产品核心参数总览
该电阻关键参数明确，可支撑大部分常规电路设计：
- 电阻类型：厚膜贴片电阻（丝网印刷+高温烧结工艺，平衡可靠性与成本）
- 阻值与精度：标称1.1kΩ，精度±1%（满足精密信号处理的一致性要求）
- 功率规格：额定功率500mW（中等功率水平，适配电源、信号放大场景）
- 工作电压：最大连续工作电压200V（避免瞬时电压超限时击穿）
- 温度特性：温度系数±100ppm/℃（阻值漂移小），工作温度-55℃至+155℃（覆盖工业级宽温环境）
- 封装与品牌：1206贴片封装（3.2mm×1.6mm，兼容常规SMT设备），罗姆（ROHM）出品
二、关键性能优势解析
2.1 厚膜工艺的可靠性
厚膜电阻通过陶瓷基底+烧结电阻膜实现，相比薄膜电阻成本更低，相比线绕电阻体积更小；抗脉冲冲击能力强，电压波动或瞬时负载下不易失效，适合工业现场等复杂环境。
2.2 高精度与宽温稳定性
- ±1%精度可直接用于精密放大器反馈、传感器分压等场景，无需额外校准；
- ±100ppm/℃温度系数：25℃→155℃时阻值漂移约1.3%，-55℃→25℃时漂移约0.8%，宽温区仍保持稳定输出。
2.3 功率与电压适配性
500mW功率支撑5V电源下100mA负载的分压电路；200V电压覆盖工业24V/48V、消费12V电源系统，无需并联电阻降电压。
2.4 1206封装的兼容性
主流封装尺寸适中，既保证功率承载，又能实现较高集成密度；兼容回流焊、波峰焊工艺，适合自动化批量生产。
三、典型应用场景
ESR18EZPF1101适配多种实际场景：
- 工业控制：PLC信号分压、温度/压力传感器调理（宽温覆盖-40℃至85℃工业环境）；
- 消费电子：音频衰减电阻、电源模块限流/分压（稳定阻值不影响音质/电源精度）；
- 通信设备：射频滤波网络、信号放大偏置电阻（高精度保证信号质量）；
- 小型电源：开关电源反馈分压网络（500mW满足中等功率需求）。
四、选型与使用注意事项
为保障长期稳定工作，需注意：
- 功率降额：实际功率不超额定70%（350mW），85℃以上进一步降额（参考罗姆官方曲线）；
- 温度限制：避免环境温度超155℃，防止电阻膜老化；
- 焊接规范：遵循罗姆回流焊曲线（峰值245℃±5℃，时长≤10秒），避免虚焊；
- 电压限制：瞬时电压≤200V，连续电压保持额定值内。
五、品牌与品质保障
罗姆具备成熟厚膜电阻工艺，ESR18EZPF1101阻值一致性好（批量波动极小），符合RoHS标准，经高温存储、温度循环测试验证，适合高要求批量项目。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
