RC-02K122JT 产品概述
一、产品简介
RC-02K122JT 是风华（FH）系列贴片厚膜电阻，封装尺寸 0402，阻值 1.2kΩ，精度 ±5%，额定耗散功率 62.5mW，最大工作电压 50V，温度系数 ±100ppm/℃，工作温度范围 -55℃ 到 +155℃。该器件体积极小，适合对尺寸和可靠性有要求的小型电子产品和高密度 SMT 线路板应用。
二、主要技术参数
- 阻值：1.2kΩ
- 精度：±5%（J）
- 功率：62.5mW（额定）
- 最大工作电压：50V
- 温度系数（TCR）：±100ppm/℃
- 工作温度：-55℃ ~ +155℃
- 封装：0402（厚膜贴片）
- 品牌：FH（风华）
三、产品特性与优势
- 小尺寸、高密度：0402 封装适合微小化与高密度布线需求。
- 稳定性良好：厚膜工艺结合较宽温度范围，适用于一般工业及消费类电子。
- 成本效益高：±5% 精度与厚膜制作工艺在数量采购时具有较优成本优势。
- 容易加工：与常规 SMT 生产线兼容，适合回流焊装配。
四、典型应用场景
- 移动与便携设备中的分压、偏置与限流电路。
- 消费电子、智能家居与物联网终端的信号处理与电路匹配。
- 通讯设备、传感器前端与一般电子产品的常规阻抗元件。
五、选型与使用建议
- 功率与热管理：在高温或接近额定功率工作时，应考虑功率余量与散热，避免长期在标称功率下连续工作。
- 电压与浪涌：不超过 50V 的工作电压，避免瞬态过压和浪涌。
- 精度与温漂：对温度系数敏感的应用请评估 ±100ppm/℃ 带来的偏差影响，必要时选用更低 TCR 的器件。
- 焊接与回流：建议按供应商推荐的回流焊工艺曲线和 PCB 焊盘设计进行装配，避免过热或机械应力导致可靠性下降。
六、包装与注意事项
- 常见为盘带（Tape & Reel）包装，便于 SMT 贴装机取料。
- 储存时保持防潮包装完整，遵循厂商的储存及干燥箱使用建议以防焊接缺陷。
- 适用前请参考风华提供的详细数据手册，以获取完整的电气特性、温度性能曲线及可靠性试验数据。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
