RC-02K8452FT 产品概述
一、产品简介
RC-02K8452FT 为风华（FH）生产的贴片厚膜电阻，封装规格为 0402（1/16W），标称阻值 84.5kΩ，精度 ±1%，额定功率 62.5mW，最高工作电压 50V。温度系数（TCR）为 ±100ppm/℃，工作温度范围 -55℃ 至 +155℃，适用于空间受限且要求中高精度的电子电路中。
二、主要性能特点
- 阻值与精度：84.5kΩ ±1%（E96 系列精密取值），适合需要较高阻值精度的电路设计。
- 功率与电压：标称功率 62.5mW（1/16W 类别），最大工作电压 50V，需保证实际应用中电压与功率不超过器件额定值。
- 温度稳定性：TCR ±100ppm/℃，在温度变化时阻值漂移较小，适合一般温度稳定性要求的模拟与数字电路。
- 封装与可靠性：0402 超小封装，便于高密度 PCB 设计与自动化贴装；厚膜工艺具有良好的制造一致性与成本优势。
三、典型应用场景
- 移动设备与可穿戴产品中的基准分压、电平设定与偏置电路。
- 家电、工业控制中的阻值配对与滤波网络（与电容器构成 RC 滤波器）。
- 模拟输入的上拉/下拉电阻、参考电阻和高阻抗测量回路。
- 任何空间受限且要求中等精度的电子设备。
四、设计注意事项
- 功率管理：0402 小封装的散热能力有限，实际功率与环境温度、PCB 铜箔面积有关，建议在设计中留有充足裕量并在高温环境下进行功率降额。
- 电压限制：单个元件最大工作电压 50V，电路设计需保证施加在该电阻两端的直流或交流电压低于此值。
- 噪声与寄生：高阻值下电阻本身的噪声与寄生电容可能影响高精度模拟信号，必要时考虑防护和布局优化。
五、焊接与储存建议
- 兼容表面贴装无铅回流焊工艺，建议按实际器件制造商提供的回流温度曲线执行，尽量避免超过元件所能承受的温度峰值与时间。
- 贴片与回流后避免强机械应力和弯曲变形；存储时防潮、防尘，长期存放建议密封包装。
六、包装与采购
- 可提供卷装（Tape & Reel）以适配自动贴片机，适用于批量生产与 SMT 线作业。
- 订购时请确认阻值、精度、封装与所需包装方式，并与供应商核对可追溯的批号与质量认证信息。
总结：RC-02K8452FT（0402、84.5kΩ、±1%、1/16W）为一款适合高密度 PCB 和中高精度需求的厚膜贴片电阻，具有体积小、制造稳定、易于自动化贴装的优点。设计时需注意功率、工作电压与环境温度对性能的影响，以保证长期可靠性。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
