ROHM ESR10EZPJ123 厚膜贴片电阻产品概述

一、产品基本参数与核心规格

ROHM ESR10EZPJ123是一款针对小型化电子设备优化的厚膜贴片电阻,核心参数覆盖通用电路的关键需求:

  • 电阻类型:厚膜贴片电阻(陶瓷基片+厚膜电阻膜工艺,兼顾功率承载与稳定性)
  • 标称阻值:12kΩ(三位数字编码“123”表示12×10³Ω,阻值清晰易识别)
  • 精度等级:±5%(满足非精密测量类电路的偏差要求,无需额外校准)
  • 额定功率:400mW(0.4W),在0805封装中属于高功率密度规格
  • 最大工作电压:150V(直流/交流峰值电压限制,避免击穿失效)
  • 温度系数(TCR):±200ppm/℃(阻值随温度变化的稳定性,适配多数环境波动)
  • 工作温度范围:-55℃~+155℃(宽温覆盖工业、汽车等恶劣场景)
  • 品牌与合规:ROHM原厂生产,符合RoHS环保标准

二、封装与物理特性

该电阻采用0805封装(英制0.08英寸×0.05英寸,对应公制2012:2.0mm×1.2mm),是贴片电阻中应用最广泛的小封装之一:

  • 尺寸紧凑:适配手机、可穿戴设备等小型PCB,不占用额外空间
  • 贴片兼容:支持自动化SMT生产,焊接效率高,适合批量制造
  • 基片耐温:高温陶瓷基片可承受回流焊峰值温度(≤260℃),无开裂风险

三、性能优势与可靠性

  1. 高功率密度:0805封装下实现400mW额定功率,相比同封装常规250mW电阻,可满足电源分压、信号调理等对功率要求更高的电路,无需升级大封装
  2. 宽温稳定性:-55℃~+155℃的工作范围,结合±200ppm/℃的TCR,在温度变化较大的场景(如户外工业设备、车载电子)中,阻值波动小,电路性能稳定
  3. 抗环境干扰:厚膜工艺形成的致密电阻膜层,抗湿气、抗机械应力(振动、冲击),适合恶劣环境长期使用
  4. 批量一致性:ROHM成熟工艺保证产品阻值、功率的一致性,减少电路调试成本

四、典型应用场景

ESR10EZPJ123凭借小封装、高功率、宽温等优势,广泛应用于以下领域:

  1. 消费电子:智能手机、平板电脑的电源分压电路、音频信号衰减电阻
  2. 工业控制:PLC输入接口限流、传感器信号调理电路
  3. 汽车电子:车载显示屏背光驱动、胎压传感器信号分压(宽温适配舱内/外环境)
  4. 通信设备:路由器以太网接口信号匹配、DC-DC转换器反馈网络
  5. 小型电源:USB-C充电器电压采样、移动电源过流保护电路

五、选型与使用注意事项

  1. 功率降额:实际使用功率建议不超过额定功率的80%(≤0.32W),避免长时间满功率运行导致热老化
  2. 电压限制:电路施加的直流/交流电压峰值不得超过150V,防止电阻击穿
  3. 焊接规范:回流焊温度曲线需符合ROHM推荐(预热150-180℃,峰值≤260℃),避免高温损坏电阻膜层
  4. 车规适配:若用于汽车电子,需确认批次是否支持AEC-Q200认证(部分型号可选)
  5. 存储条件:未焊接电阻存储在常温(15-35℃)、干燥(湿度≤60%)环境,避免受潮影响焊接性能

该电阻以高性价比满足通用电路的功率、温度需求,是小型化电子设备的优选无源器件。

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.

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
