SC1206F2002F8ANRH 厚膜贴片电阻产品概述

一、产品基本定位与属性

SC1206F2002F8ANRH是信维通信(Sunway)推出的1206封装通用厚膜贴片电阻,适配自动化表面贴装(SMT)生产流程,覆盖工业级、消费级及汽车电子等多场景需求。型号命名中:

  • “SC”为信维品牌前缀;
  • “1206”对应英制封装尺寸(公制3216);
  • “F2002”代表阻值20kΩ(20×10²Ω);
  • “8A”关联±1%精度等级;
  • “NRH”为系列标识与包装规范。

二、核心性能参数详解

产品参数围绕电路设计核心需求优化,关键指标如下:

2.1 阻值与精度

阻值标称20kΩ,精度±1%——属于工业级通用精度,可满足信号调理、分压电路、限流保护等场景的匹配需求,避免因阻值偏差导致电路性能波动(如采样电路的电压误差控制在0.2V以内)。

2.2 功率与电压限制

  • 额定功率:250mW(0.25W)——1206封装的常规功率等级,实际使用建议降额至80%(200mW),延长长期稳定性;
  • 最大工作电压:200V——需结合功率公式校验实际允许电压:$U \leq \sqrt{P \times R} = \sqrt{0.25 \times 20000} \approx 70.7V$,即实际应用中电压需以功率限制为准(≤70.7V),避免过压损坏。

2.3 温度特性

  • 温度系数(TCR):±100ppm/℃——每变化1℃,阻值变化±0.01%;以25℃为基准,在-55℃~+155℃范围内,阻值最大偏差为±1%(125℃温差下),满足宽温环境下的阻值稳定性;
  • 工作温度范围:-55℃~+155℃——覆盖车载低温启动、工业高温作业等极端场景。

2.4 封装与尺寸

封装为1206(长3.2mm×宽1.6mm×厚≈0.5mm),符合IPC-J-STD-020标准,适配常规SMT贴片机,焊接兼容性强。

三、工艺与可靠性特点

信维通信采用成熟厚膜工艺,保障产品一致性与可靠性:

  1. 厚膜烧结工艺:通过丝网印刷电阻浆料于氧化铝陶瓷基底,经高温烧结成型,阻值一致性优于薄膜工艺,且耐湿性更强;
  2. 环保无铅终端:采用镀锡/镀镍终端处理,符合RoHS/REACH标准,兼容无铅回流焊(峰值温度≤260℃)、波峰焊,焊接后焊点剪切强度≥10N;
  3. 可靠性测试:通过-55℃~+155℃温度循环(1000次)、高温存储(155℃/1000h)测试,阻值漂移≤0.5%,满足工业级5年以上寿命需求。

四、典型应用场景

结合参数特点,本款电阻适用于以下场景:

  1. 消费电子:手机、平板、智能穿戴的电源分压、信号滤波电路;
  2. 工业控制:PLC模块、传感器接口的限流、电压采样电路;
  3. 汽车电子:车载中控、胎压监测、传感器电路(宽温适配车载环境);
  4. 通信设备:路由器、基站的射频匹配、信号调理电路;
  5. 医疗仪器:小型监护仪、血糖仪的电路限流与分压。

五、使用注意事项

  1. 功率降额:实际功率≤200mW,避免高温老化;
  2. 电压校验:需同时满足$U \leq 70.7V$(功率限制)与$U \leq 200V$(绝缘限制);
  3. 焊接规范:回流焊峰值温度≤260℃,时间≤30s,避免陶瓷基底开裂;
  4. 存储条件:常温干燥环境(湿度≤60%),开封后1个月内使用完毕;
  5. 精度匹配:若需更高精度(如±0.1%),需选择薄膜电阻,本款±1%满足多数通用需求。

六、总结

SC1206F2002F8ANRH作为信维通信的通用厚膜贴片电阻,以**±1%精度、250mW功率、宽温适应性**为核心优势,适配多行业电子电路需求,同时具备工艺成熟、可靠性高、SMT兼容性强等特点,是工业、消费、汽车电子等领域的高性价比选型。

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.
