ESR10EZPJ202厚膜贴片电阻产品概述

ESR10EZPJ202是罗姆(ROHM)推出的一款0805封装厚膜贴片电阻,凭借稳定的电气性能、宽温区适配能力及成熟的工艺优势,广泛应用于工业控制、消费电子等领域,是中小功率电路的常用电阻选型。

一、产品基本属性

该电阻属于罗姆标准厚膜贴片电阻系列,型号编码清晰对应核心参数:

  • 品牌:ROHM(罗姆)
  • 封装:0805(英制尺寸,约2.0mm×1.2mm)
  • 类型:厚膜贴片电阻
  • 型号:ESR10EZPJ202(其中“202”为阻值编码:20×10²=2kΩ)

封装符合SMT标准规格,适配回流焊、波峰焊等自动化贴装工艺,适合批量生产需求。

二、核心电气参数解析

1. 阻值与精度

标称阻值为2kΩ(2000Ω),精度等级为**±5%**,属于E24系列标准精度,满足大多数电路对电阻值的基本匹配需求(无需高精度场景时可有效控制成本)。

2. 功率与电压限制

  • 额定功率:400mW(0.4W),可承受中小功率电路的功耗负载;
  • 最大工作电压:150V,需注意功率与电压的关联:当工作电压接近150V时,实际功耗为(P=V^2/R=150^2/2000=112.5mW),远低于额定功率,因此电压限制为主要安全边界。

3. 温度特性与工作温区

  • 温度系数(TC):±200ppm/℃,表示温度每变化1℃,阻值变化约±0.4Ω((2000Ω×200×10^{-6})),阻值稳定性满足常规电路需求;
  • 工作温区:-55℃~+155℃,覆盖工业级及高温环境(如汽车电子局部、工业现场),比普通商业级电阻(0℃~70℃)适配性更强。

三、厚膜电阻技术优势

  1. 工艺成熟稳定:采用厚膜丝网印刷+高温烧结工艺,膜层附着力强,批量生产的阻值一致性误差控制在±5%以内,良率高;
  2. 宽功率适配:0805小封装下实现400mW额定功率,热 dissipation能力优于同封装薄膜电阻,不易因过载导致阻值漂移;
  3. 环境耐受性:厚膜结构对湿度、粉尘等环境因素耐受性较好,可在户外或半 harsh环境下稳定工作;
  4. 成本优势:相比薄膜电阻,厚膜工艺成本更低,适合中低端及常规电路的大规模应用。

四、典型应用场景

  1. 消费电子:智能手机、平板的电源滤波电路、音频信号偏置电阻,适配0805封装的小型化需求;
  2. 工业控制:PLC(可编程逻辑控制器)的输入输出接口电阻、传感器信号调理电路(如温度传感器分压);
  3. 汽车电子(局部):汽车仪表背光电路、中控辅助电路(非 safety关键路径,适配155℃高温);
  4. 电源模块:DC-DC转换器的反馈分压电阻、线性电源的限流电阻,400mW功率满足中小功率电源需求。

五、选型与使用注意事项

  1. 功率降额:环境温度超过25℃时需遵循降额原则(如罗姆降额表显示:100℃时功率降额至约60%,155℃时降额至约30%),避免过载损坏;
  2. 焊接工艺:回流焊峰值温度需控制在240℃~250℃,焊接时间不超过60秒,避免过热导致膜层脱落或阻值漂移;
  3. 存储条件:未使用的电阻需存储在干燥环境(湿度<60%)、温度0℃~40℃,避免长期暴露在潮湿环境影响引脚可焊性;
  4. 电压限制:严禁超过150V最大工作电压,避免击穿损坏。

该电阻综合性能均衡,是常规电路中替代同参数进口/国产电阻的可靠选型,适合对成本敏感且需宽温适配的应用场景。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
