ERJ2RKF1403X 厚膜贴片电阻产品概述

一、产品核心身份与定位

ERJ2RKF1403X是松下(PANASONIC)推出的厚膜贴片电阻,属于其经典ERJ系列贴片电阻产品。该型号采用0402小型化封装,以140kΩ±1%高精度、100mW低功耗为核心特征,定位为通用型小型化贴片电阻,适用于对体积、精度有明确要求的电子电路设计。

二、基础电气参数详解

该电阻的核心电气参数直接决定其适用场景,具体如下:

  1. 阻值与精度:标称阻值140kΩ,精度±1%——此精度属于工业级常用范围,可满足多数电路对阻值偏差的控制需求(如信号分压、电流采样等场景);阻值代码“1403”对应140×10³Ω,符合贴片电阻的标准编码规则。
  2. 功率与电压:额定功率100mW,额定工作电压100V——功率等级适配0402封装的小型化设计,适合低功耗电路;需注意功率与电压的约束关系(P=V²/R),实际应用中需避免同时超过功率与电压额定值(如100V下的功耗为100mW,符合额定要求)。
  3. 温度系数(TCR):±100ppm/℃——表示温度每变化1℃,阻值变化±140kΩ×100×10⁻⁶=±14Ω,该指标在宽温环境下可保持阻值相对稳定,满足一般工业与消费电子的温度适应性要求。

三、物理封装与工艺特性

ERJ2RKF1403X采用0402封装(英制尺寸:0.04英寸×0.02英寸,公制1005),是目前贴片电阻中体积较小的封装类型之一,具有以下工艺与封装优势:

  • 贴装密度高:可在单位面积PCB上实现更多电阻的贴装,适合智能手机、可穿戴设备等小型化产品的高密度电路设计;
  • 厚膜工艺优势:采用丝网印刷+高温烧结工艺制造,相比薄膜电阻成本更低,且稳定性良好,适合批量生产;
  • 无铅环保:符合RoHS与REACH等国际环保标准,满足现代电子产业的绿色制造要求(松下产品默认符合此类标准)。

四、环境适应性表现

该电阻的环境适应性参数覆盖了多数应用场景的需求:

  • 工作温度范围:-55℃+155℃——此范围超出普通工业级(-40℃+85℃),可适应高温环境(如汽车电子的部分高温区域、工业控制设备的高温模块)与低温环境(如户外电子设备的低温工况);
  • 温漂稳定性:结合±100ppm/℃的TCR,在工作温度范围内,阻值变化幅度可控,不会对电路性能造成显著影响(如对精度要求不苛刻的信号调理电路)。

五、品牌可靠性与典型应用

作为松下旗下产品,ERJ2RKF1403X继承了松下电子元器件的可靠性优势:

  • 品质控制:松下对厚膜电阻的生产工艺(如丝网印刷精度、烧结温度控制)有严格标准,产品一致性好,批量应用时故障率低;
  • 典型应用场景:
    1. 消费电子:智能手机、平板电脑的电源滤波电路、音频信号调理电路;
    2. 工业控制:小型PLC的I/O接口电路、传感器信号放大电路;
    3. 汽车电子:车载信息娱乐系统的辅助控制电路(适配155℃的高温工况);
    4. 可穿戴设备:智能手表、手环的低功耗传感器电路。

六、选型注意事项

在选用该电阻时,需注意以下几点:

  • 需确认电路的最大功耗与电压是否在100mW、100V的额定范围内;
  • 若电路对温度系数要求更高(如精密测量电路),需评估±100ppm/℃是否满足需求;
  • 0402封装对贴装工艺要求较高,需确保生产设备的贴装精度适配。

该产品凭借小型化、高精度与宽温适应性,成为众多电子设备中通用贴片电阻的可靠选择。

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
