AR03FTC1212 产品概述
一、产品简介
AR03FTC1212 为 Viking(光颉) 系列薄膜贴片电阻，封装规格为 0603（约 1.6 × 0.8 mm）。标称阻值 12.1 kΩ，公差 ±1%，额定功率 62.5 mW，最高工作电压 50 V。温度系数（TCR）优良，为 ±25 ppm/℃，工作温度范围 -55℃ 至 +155℃，适合对稳定性与精度有较高要求的小型化电路设计。
二、主要特性
- 薄膜工艺，低噪声、低漂移、长期稳定性好；
- 精度 ±1%，适用于精密分压、滤波及测量电路；
- 低 TCR（±25 ppm/℃），在温度变化下阻值波动小；
- 小封装 0603，适配高密度 SMT 布局，节省 PCB 面积；
- 宽温工作范围（-55 ~ +155℃），适用于工业级及恶劣环境。
三、典型应用场景
- 精密模拟电路：运放输入网络、反馈回路、分压器等；
- 传感器与测量仪器：需稳定阻值和低热漂的前端电路；
- 通信与信号处理设备：滤波器、偏置网络；
- 工业控制、汽车电子（需按额定及可靠性要求选型）。
四、选型与注意事项
- 功率与降额：额定功率 62.5 mW 在标准温度条件下适用，高温环境需按厂方功率降额曲线处理；
- 最大工作电压 50 V，应确保电路中的实际电压与额定值匹配；
- 考虑焊接与热应力，建议按行业标准的回流焊工艺和温度曲线焊接；
- 对于极低噪声或超高稳定性需求，可与更高精度或特殊工艺电阻对比评估。
五、封装与可靠性
AR03FTC1212 提供带卷带（Tape & Reel）包装，便于自动贴装与大批量生产。薄膜材料与制造工艺保证长时间稳定性和低老化特性，适合要求可靠性的产品开发。存储和搬运时建议做好防潮与防静电措施，避免机械刮擦。
六、采购与支持

Request for quote
Send RFQ
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.
