ERJ2RKF1912X 产品概述

一、产品简介

ERJ2RKF1912X 是 PANASONIC(松下)系列的贴片厚膜电阻,阻值为 19.1 kΩ,精度 ±1%,封装为 0402。该型号面向对体积、可靠性和中低功率需求较高的消费与工业类电子产品,提供稳定的阻值与良好的温度特性,适合高密度电路板的表贴组装。

二、主要技术参数

  • 电阻类型:厚膜电阻
  • 阻值:19.1 kΩ
  • 精度:±1%
  • 额定功率:100 mW
  • 最大工作电压:50 V
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 封装:0402(表面贴装)

三、性能特点

  • 小型化封装(0402)适用于高密度贴片设计,节省 PCB 空间。
  • ±1% 精度满足多数模拟信号处理、分压和偏置电路的需求。
  • ±100 ppm/℃ 的温度系数在温度变化场合仍能保持较好的阻值稳定性。
  • 宽温工作范围,能够适应工业级温度环境。
  • 厚膜工艺成本效益高、可靠性良好,适合大批量生产应用。

四、典型应用

  • 分压器、偏置网络与滤波器电路
  • 模拟与数字信号处理电路中的定值与限流元件
  • 移动设备、消费电子、工业控制与通信设备的表贴设计
  • 高频率要求不极端的电路(厚膜电阻适合一般频段使用)

五、布局与安装建议

  • 0402 封装尺寸较小,贴片时需使用高精度贴装与回流焊工艺以确保焊点可靠。
  • 在高功率或高温环境中注意功率降额和散热路径,避免长期接近额定功率。
  • 遵循厂商推荐的 PCB 过孔与焊盘尺寸,保证焊接质量并减少热应力。
  • 对关键阻值应用可在设计时考虑冗余或配对校准以提高系统精度。

六、选型及注意事项

  • 若电路工作电压或瞬态超过 50 V,应选择更高工作电压或更大封装功率的电阻。
  • 对于更严格的温漂或更高精度需求,可考虑薄膜或金属膜电阻。
  • 批量采购时建议参考松下官方规格书确认回流焊曲线与可靠性试验要求,确保满足具体应用环境。

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
