0805W8F2402T5E 产品概述

一、产品简介

0805W8F2402T5E 为 UNI-ROYAL(厚声)品牌的贴片厚膜电阻,封装规格为0805(英制),阻值 24 kΩ,精度 ±1%。该器件适用于通用表面贴装电路,常用于分压、限流、偏置及信号处理等电路场合,兼顾成本与稳定性,适合大批量制造和贴片回流焊工艺。

二、主要参数

  • 电阻类型:厚膜电阻(SMD Thick Film)
  • 封装:0805(2012公制尺寸)
  • 标称阻值:24 kΩ(24000 Ω)
  • 精度:±1%
  • 额定功率:125 mW(0.125 W)
  • 最高工作电压:150 V
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度范围:-55 ℃ 至 +155 ℃
  • 品牌:UNI-ROYAL(厚声)

三、性能特点

  • 成本效益高:厚膜工艺使得器件在保证基本电学性能的同时具备较低成本,适合量产应用。
  • 尺寸小、易贴装:0805 封装适应常见贴片机和回流焊流程,节省 PCB 面积。
  • 精度可控:±1% 精度满足多数模拟和数字电路的阻值要求。
  • 宽温度范围:-55 ℃ 至 +155 ℃ 的工作温度范围适合工业级和环境复杂场合。
  • TCR 中等:±100 ppm/℃ 在温度变化不大的场景下表现稳定;对于高精度、低漂移需求可考虑更低 TCR 的金属膜或薄膜电阻。

四、典型应用场景

  • 分压器和电压采样网络:适用于需中高阻值且精度要求为 1% 的电路。
  • 信号偏置与限流:在模拟前端、放大器偏置网络中常用。
  • 消费电子与工业控制:如传感器接口、驱动电路、控制板等。
  • 通用 SMT 组装与自动化生产线:与常见焊接与检测流程兼容。

五、设计与使用建议

  • 功率与温升:额定功率为 125 mW,设计时应考虑工作环境温度与 PCB 热阻,必要时对功率进行降额处理以延长寿命。
  • 温漂与精度:±100 ppm/℃ 的 TCR 在温度波动较大的应用中会引起显著阻值变化,若为高精度测量或温度敏感电路,建议选用更低 TCR 器件或采取温度补偿。
  • 布局与焊接:遵循 0805 封装的 PCB 推荐焊盘布局,保证足够的焊锡端接长度以提高焊接可靠性。器件兼容标准回流焊工艺,具体焊接曲线请参照厂商资料。
  • 过压与冲击:最高工作电压 150 V,电路设计应避免瞬态过压和长时间高压应力,以防击穿或阻值漂移。
  • 选型与替代:若需更高稳定性或更低噪声,可考虑薄膜/金属膜 SMD 电阻;若需更高功率,可向更大封装(1206、2010 等)或功率型电阻过渡。

六、品质与采购建议

在采购前建议向供应商索取完整规格书(datasheet),核实电阻的焊接温度、耐湿性(如需)、阻值系数及可靠性试验结果(如寿命、热冲击、机械强度等)。对于批量生产,建议索取样品进行实际电路验证并评估在目标环境下的长期漂移和可靠性表现。

总结:0805W8F2402T5E 是一款面向通用电子产品的经济型厚膜贴片电阻,24 kΩ、±1% 的配置适合绝大多数分压与偏置应用。设计时需注意功率热管理与温漂影响,并参考厂商完整数据以获得最佳使用效果。

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
