KTR03EZPF2701 厚膜贴片电阻产品概述

一、产品基本信息

KTR03EZPF2701是日本罗姆(ROHM)推出的0603封装厚膜贴片电阻,属于罗姆电阻产品线中的常规精度系列。型号中各标识对应明确:

  • “KTR”为罗姆电阻系列专属编码;
  • “03”直接对应0603封装(英制尺寸:0.06英寸×0.03英寸,公制1.6mm×0.8mm);
  • “EZPF”代表厚膜工艺+常规精度等级;
  • “2701”为阻值编码(27×10¹=2700Ω=2.7kΩ)。

该产品定位为中小功率通用型电阻,兼顾体积、成本与性能,适配多数电子设备的基础电阻需求。

二、核心性能参数解析

1. 阻值与精度要求

标称阻值为2.7kΩ,精度等级±1%——即实际阻值与标称值的偏差范围为±27Ω(2.7kΩ×1%)。此精度属于电子领域“常规精度”范畴,可满足信号调理、分压、限流等电路的基本稳定性需求,无需额外校准即可实现功能。

2. 功率与电压限制

  • 额定功率:100mW(25℃环境下长期稳定工作的最大允许功耗);
  • 最大连续工作电压:350V。

需注意两者的协同约束:根据公式(P=V^2/R),当电压达350V时,功耗仅约45.4mW(远低于100mW),因此电压限制(350V)是更严格的应用边界,需避免电路中出现超压信号(如瞬态尖峰)。

3. 温度系数与温漂特性

温度系数(TCR)为**±100ppm/℃**,表示环境温度每变化1℃,阻值相对变化百万分之一百。以工作温区(-55℃~+155℃)为例:
从常温(25℃)到最高温(155℃)温差130℃,阻值最大变化约±35.1Ω(2.7kΩ×100ppm/℃×130℃),可满足一般宽温场景需求(若需精密温漂控制,需选低TCR产品)。

三、封装与适用场景

1. 0603封装的核心优势

采用超小型贴片封装,体积仅1.6mm×0.8mm×0.45mm左右,适配高密度PCB布局——尤其在便携电子(如智能手机、可穿戴设备)中,能有效节省空间、提升集成度;同时兼容自动化贴装设备,适合大规模批量生产。

2. 典型应用领域

结合参数特性,该电阻主要覆盖以下场景:

  • 消费电子:智能手机电源管理(限流、分压)、蓝牙耳机信号调理;
  • 工业控制:传感器接口(如温度传感器放大)、小型PLC输入输出电路;
  • 通信设备:路由器/交换机滤波网络、信号衰减电路;
  • 汽车电子(辅助级):车载中控低功耗控制电路(需确认官方汽车级认证)。

四、可靠性与环境适应性

1. 宽温工作范围

工作温度覆盖**-55℃~+155℃**,适配极寒户外设备(-55℃)到高温工业控制柜(155℃),无需额外温度补偿,稳定性能贯穿全温区。

2. 厚膜工艺的可靠性

采用厚膜电阻工艺,相比薄膜电阻成本更低,且抗机械应力、抗潮湿性能更优;罗姆通过严格工艺控制(如浆料配比、烧结温度),确保同一批次产品阻值偏差、温漂波动极小,适合对批量一致性要求高的客户。

五、品牌与品质保障

KTR03EZPF2701由罗姆(ROHM)生产,作为全球知名半导体厂商,其被动元件具备三大优势:

  • 环保合规:符合RoHS标准(无铅、无镉),满足欧盟及国内环保法规;
  • 可靠性验证:通过温度循环、湿度老化、耐电压测试等多项罗姆内部严苛测试,长期性能稳定;
  • 市场验证:广泛应用于苹果、华为、博世等全球知名品牌产品,品质得到行业认可。

该产品以“小体积+常规精度+宽温适应性”为核心卖点,是电子设备中小功率电阻的高性价比选择。

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
