SC0805F2002F4ANRH 厚膜贴片电阻产品概述

SC0805F2002F4ANRH是信维通信(Sunway)针对中低功率电路设计的0805封装厚膜贴片电阻,核心定位为兼顾性价比与稳定性能的通用型电阻,广泛适配消费电子、工业控制等多领域电路需求。

一、产品基本定位与封装工艺

  1. 封装规格:采用行业通用的0805贴片封装(尺寸2.0mm×1.2mm),兼容自动化SMT贴装工艺,适合批量生产场景,同时具备紧凑体积,可有效节省电路板空间;
  2. 工艺特点:基于厚膜电阻工艺制造,通过丝网印刷电阻浆料并高温烧结而成,兼具成本优势与性能稳定性,抗机械应力能力优于部分薄膜电阻,适合常规应用环境;
  3. 品牌背书:由信维通信(国内知名电子元器件与通信天线厂商)出品,产品符合RoHS、REACH等环保标准,出厂前经过严格的参数测试与可靠性验证。

二、核心电气性能参数

本型号电阻的关键参数针对实用场景优化,具体如下:

  • 阻值与精度:标称阻值20kΩ,精度±1%,能满足多数电路对阻值偏差的实用要求(如模拟信号调理、数字电路上拉/下拉等),避免因精度不足导致的电路参数偏移;
  • 功率与电压:额定功率125mW,最大工作电压150V,适用于低功率信号处理、偏置电路等场景(需注意实际电路功耗需低于额定功率,否则会导致阻值漂移甚至损坏);
  • 温度系数:±100ppm/℃,表示温度每变化1℃,阻值变化±0.01%;结合-55℃~+155℃的宽温范围,极端温度下(如汽车发动机舱、工业户外设备)阻值最大变化约±2.1%(210℃温差×100ppm),仍保持较高稳定性;
  • 工作温度范围:覆盖-55℃至+155℃,超出多数消费电子温区(0℃~70℃),可适配工业控制、汽车电子等对温宽要求较高的场景。

三、环境适应性与可靠性

  1. 宽温稳定性:±100ppm/℃温度系数与宽温范围结合,无需额外温度补偿电路,降低系统设计复杂度;
  2. 抗环境干扰:厚膜工艺与0805封装的气密性设计,可抵抗潮湿、灰尘影响,短时间内可承受1.5倍额定功率的过载;
  3. 焊接兼容性:适配常规SMT回流焊工艺(温度曲线符合IPC标准),焊接后无虚焊、脱落问题,可靠性符合电子行业通用标准。

四、典型应用场景

本型号电阻因性能适配性强,广泛应用于:

  • 消费电子:智能手机、平板电脑的电源管理电路(DC-DC转换偏置电阻)、信号滤波电路;
  • 工业控制:PLC输入输出接口上拉/下拉电阻、传感器信号调理电路(压力/温度传感器偏置);
  • 汽车电子:车载信息娱乐系统信号分配电路、车身传感器模块(胎压监测)偏置电阻;
  • 通信设备:路由器、交换机信号衰减网络、射频前端偏置电路(需匹配功率需求)。

五、选型与使用注意事项

  1. 功率匹配:实际功耗需低于125mW(如1mA电流时功率20mW,符合要求;2.5mA时功率125mW,需留余量);
  2. 电压限制:工作电压不得超过150V,避免绝缘击穿;
  3. 环境温度:使用范围需在-55℃~+155℃内,超出可能导致阻值漂移;
  4. 精度需求:若需±0.1%等高精度,需换用更高规格型号,本型号适合常规实用场景。

总结:SC0805F2002F4ANRH凭借稳定性能、宽温适应性与高性价比,成为中低功率电路的通用优选电阻,可满足多领域电子设备设计需求。

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
