RC-02K7682FT 产品概述
一、产品简介
RC-02K7682FT 为风华（FH）系列厚膜贴片电阻，封装尺寸 0402（公制 1005），标称阻值 76.8kΩ，阻值精度 ±1%，额定功率 1/16W（62.5mW），额定工作电压 50V，温度系数（TCR）±100ppm/℃，工作温度范围 -55℃ ~ +155℃。此型号针对体积受限、高密度表面贴装电路提供稳定的电阻解决方案，适合商业及工业类电子设备中使用。
二、主要参数（要点）
- 阻值：76.8kΩ
- 精度：±1%（线性精度）→ 绝对误差约 ±768Ω
- 功率：62.5mW（1/16W）
- 最大工作电压：50V（额定）
- 温度系数：±100ppm/℃ → 每摄氏度阻值变化约 ±7.68Ω
- 工作温度：-55℃ ~ +155℃
- 封装：0402（适用于自动贴装）
三、关键性能与特点
- 小型化封装，适配高密度 PCB 布局，实现更高的组件集成度。
- ±1% 精度满足对阻值要求较高的电路（分压、偏置、阻抗匹配等）。
- ±100ppm/℃ 的温漂在多数一般电子应用中提供良好温度稳定性。
- 额定工作电压 50V 与阻值配合下，V^2/R = 50^2 / 76800 ≈ 32.6mW，低于额定功率，留有安全裕量。
- 采用厚膜制程，具有良好的批次一致性和成本效益。
四、典型应用场景
- 移动设备与可穿戴电子的偏置与分压网络
- 模拟电路的反馈与限流电阻
- 传感器前端与检测电路阻抗匹配
- 工业控制与消费类电子中对体积及成本敏感的电阻应用
五、使用与设计注意事项
- 功率与环境温度：在高温环境下应对额定功率进行降额处理，避免长时间在高于室温的大功率工作。
- 最大工作电压已按阻值限定，实际电路设计中仍需校验瞬态过压与脉冲情况。
- 温度系数：对高精度或宽温度范围的设计，应考虑 TCR 带来的阻值变化对电路影响。
- 焊接兼容性：兼容常规表面贴装回流焊工艺（请选择符合工艺的回流温度曲线并遵循厂方焊接指南）。
- PCB 设计：建议参照 IPC 标准（如 IPC‑7351）设计 0402 的焊盘与阻焊，保证焊点可靠性与可回流效果。
- 机械应力：避免在回流后对器件施加过大弯折或机械应力，以免造成阻值漂移或损坏。
六、质量与可靠性
此类厚膜贴片电阻通常经过湿热、温度循环、耐焊接性及机械冲击等老化与可靠性测试，以满足工业级使用要求。实际可靠性数据请参考风华出厂的规格书与检验报告。
七、包装与采购建议
常见供应形式为卷带（Tape & Reel），便于贴片机自动化装配。选型时请确认包装单位、批号与规格书一致，批量采购建议索取样品评估在目标工况下的表现，并确认供应商的长期可供货能力。

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.
