ESR03EZPJ162 产品概述

一、产品简介

ESR03EZPJ162 为 ROHM(罗姆)出品的 0603 封装贴片厚膜电阻,阻值 1.6 kΩ,公差 ±5%,额定功率 0.25 W(250 mW),适用于空间受限且对成本与通用性能有要求的电子产品。该器件支持宽温工作范围,旨在满足消费类、工业及通讯设备中常见的偏置、分压与限流等电路需求。

二、主要技术参数

  • 阻值:1.6 kΩ
  • 精度(容差):±5%
  • 额定功率:250 mW(室温额定)
  • 最大工作电压:150 V
  • 温度系数(T.C.R):±200 ppm/°C
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 结构类型:厚膜电阻(贴片)
  • 封装:0603(公制 1608)

三、产品特性与优势

  • 体积小、适合高密度贴装:0603 封装尺寸有利于节省 PCB 面积,适配自动贴装与回流焊工艺。
  • 成本效益高:厚膜工艺在中低精度与常规功率场景下具有良好的性价比。
  • 宽温度适应:-55 ℃ 至 +155 ℃ 的工作温度范围,可覆盖从一般消费电子到部分工业级应用的环境要求。
  • 较高的额定工作电压:150 V 的最高工作电压使其可用于较高电压的分压与偏置回路(使用时需考虑功率和电压同时限制)。

四、典型应用场景

  • 信号电路的分压器和偏置网络。
  • 单片机或逻辑电路中的上拉/下拉电阻。
  • 模拟电路中的增益设定与滤波网络(配合电容使用)。
  • LED 限流(需检查功率和最大工作电压是否满足实际条件)。
  • 通用电子产品、家电、车载信息娱乐子系统(非安全关键路径)及通信设备的常规阻值需求。

五、可靠性与环境适应性

  • 厚膜材质在常规环境下具有良好的长期稳定性,但相较于金属膜电阻,长期漂移和噪声水平可能略高。
  • 工作环境中应关注功率热耗散与 PCB 散热条件:250 mW 为额定功率,实际使用时需根据环境温度和散热情况进行功率降额(具体降额曲线请参考 ROHM 官方资料)。
  • 建议在高湿、化学污染或强振动环境下评估可靠性并进行必要的封装或保护处理。

六、封装、焊接与使用注意事项

  • 推荐使用规范的回流焊工艺,遵循 ROHM 或 PCB 制造商提供的回流温度曲线。避免超过最大焊接温度与多次高温循环以减少热应力导致的阻值漂移或失效。
  • 贴片放置时避免对端接端电极产生过大的机械应力,焊盘设计应保证良好焊接并便于热散。
  • 使用前后注意防潮存放,开盘后若长期未用建议回流前进行干燥处理。
  • 在高压或高功率应用中,应同时满足电压、功率和环境温度的限制,必要时选择更大功率或更高耐压的器件。

七、选型与订购建议

  • 在设计阶段优先核实功耗与预期最高工作温度下的实际耗散,必要时按厂家降额曲线选择更高功率等级或增大封装尺寸。
  • 如果对阻值精度、温漂或噪声有更高要求,可考虑金属膜或薄膜电阻替代。
  • 订购时请确认完整型号、封装与包装方式(卷带、带装等),并参考 ROHM 官方数据手册获取详细电气特性、热耗散和回流焊曲线。

如需我帮您核对实际电路中的功率耗散、计算降额后可用功率或推荐替代型号,请提供工作点电压/电流与工作环境温度等参数。

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
