0402WGF2553TCE厚膜贴片电阻产品概述

一、产品基本定位与核心属性

0402WGF2553TCE是UNI-ROYAL(厚声) 推出的一款0402封装厚膜贴片电阻,属于通用型小功率电阻范畴。其核心定位是满足小型化、低功耗电路的阻值控制需求,兼具一定的温度稳定性与环境适应性,适用于消费电子、工业控制、便携设备等多领域的常规电路设计。

二、核心性能参数详解

该电阻的关键性能参数明确,可支撑大多数常规电路的参数要求:

1. 阻值与精度

标称阻值为255kΩ,精度等级为**±1%**——这是电子电路中最常用的精度等级之一,能满足分压、限流、信号放大等场景对阻值偏差的基本要求(例如,在模拟信号调理电路中,±1%的精度可避免信号失真过大)。

2. 功率与电压额定值

  • 额定功率:62.5mW(0.0625W),对应0402封装的典型功率等级,适合低功耗电路(如可穿戴设备的传感器供电电路);
  • 最大工作电压:50V(厂商明确标注的直流/交流峰值电压上限),需注意电路中实际电压不得超过此值,避免击穿损坏。

3. 温度系数与工作范围

  • 温度系数(TCR):±100ppm/℃——即每变化1℃,阻值变化±0.01%。在工作温度范围内(-55℃~+155℃),最大阻值变化为±21000ppm(±2.1%),叠加初始±1%精度,总阻值偏差约±3.1%,可满足温度变化不剧烈的场景;
  • 工作温度:-55℃至+155℃,覆盖工业级应用的高低温环境(如户外传感器模块、车载辅助电路),抗温变能力优于部分薄膜电阻。

三、封装与尺寸规格

采用0402封装(英制:0.04英寸×0.02英寸;公制:1.0mm×0.5mm),属于超小型贴片封装,适配表面贴装技术(SMT)的自动化生产。其体积仅为常规1206封装的1/25左右,可大幅提升PCB的集成密度,适合智能手环、蓝牙耳机、小型医疗设备等对空间要求苛刻的产品。

四、典型应用场景

结合性能参数,0402WGF2553TCE的主要应用场景包括:

1. 便携低功耗设备

  • 智能穿戴:智能手环/手表的心率传感器分压电路、蓝牙模块的限流电阻;
  • 蓝牙耳机:音频信号调理电路的反馈电阻、充电电路的限流元件。

2. 小型电子模块

  • 传感器接口:温度/湿度传感器的信号分压网络(耐高低温);
  • LED驱动:小型指示灯的低电流限流电阻(如遥控器状态灯)。

3. 工业与车载辅助电路

  • 工业控制:PLC模块的辅助信号电阻(耐温范围匹配工业环境);
  • 车载小部件:车载USB充电口的过流保护辅助电阻(符合车载温湿度要求)。

五、可靠性与工艺优势

作为厚膜电阻,该产品具备以下可靠性优势:

  • 工艺稳定:采用陶瓷基片+厚膜印刷烧结工艺,阻值一致性好,长期使用漂移小;
  • 抗环境应力:耐冲击、振动性能优于薄膜电阻,适合移动设备或工业振动场景;
  • 环保合规:符合RoHS 2.0、REACH等环保标准,无铅无卤,适配全球市场要求。

六、品牌与品质保障

UNI-ROYAL(厚声)是国内电阻行业的头部厂商,拥有20余年的电子元件制造经验,产品通过ISO9001质量管理体系、IATF16949汽车级认证,0402WGF系列电阻供货稳定,可满足批量生产需求。

该产品以高性价比、小体积、宽温适应性为核心优势,是小型化电路设计中阻值控制的可靠选择。

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
