CRCW0402182KFKED 产品概述
一、主要参数
- 型号：CRCW0402182KFKED（VISHAY 威世）
- 电阻类型：厚膜贴片电阻（SMD）
- 阻值：182 kΩ
- 精度：±1%
- 额定功率：63 mW（0402 封装典型值）
- 最高工作电压：50 V
- 温度系数（TCR）：±100 ppm/℃
- 工作温度范围：-55 ℃ ~ +155 ℃
- 封装：0402（约 1.0 × 0.5 mm）
二、产品特性与电气性能
CRCW0402182KFKED 采用厚膜工艺制造，经济且适用于批量SMT组装。182kΩ 的阻值适合高阻偏置、拉高/拉低网络以及与高阻容配合的时间常数电路。±1% 精度在多数模拟和数字电路中能保证稳定的阻值配对与偏置精度。±100 ppm/℃ 的温漂在环境温度变化时表现为中等稳定性，需在精密度要求更高的场合评估是否采用薄膜电阻替代。
额定功率为63 mW，在实际应用中应考虑热降额和环境温度影响；最高工作电压 50 V 表示在超过该电压时可能出现击穿或绝缘失效风险。
三、典型应用场景
- 模拟电路偏置与分压器（高阻偏置）
- ADC/DAC 输入滤波与源阻隔离
- 低功耗便携设备中的拉高/拉低电阻
- 定时电路中与电容形成长时间常数的RC网络
- 一般电子产品、通信设备、传感器接口与消费类电子量产装配
四、使用建议与注意事项
- 功率与温度：建议按厂商热降额曲线使用，在高温环境下线性降额至额定功率以下，避免长期靠近极限值。
- 布局与散热：0402 尺寸小，热阻较大，若需要承载接近额定功率的能量，应提供较好的铜箔散热路径或避免集中发热元件。
- 高阻电路注意漏电流与噪声，电路板表面洁净度对高阻值的稳定性影响较大，建议清洗并采用良好绝缘处理。
- 焊接：遵循Vishay推荐的回流焊工艺曲线，避免过长的高温暴露；常见的无铅回流温度峰值为 240℃ 左右，具体以厂方建议为准。
- 阻值配对与温漂：若用于温度敏感或高精度测量，应评估 ±100 ppm/℃ 带来的误差并考虑温度补偿或选用低TCR产品。
五、包装与采购
CRCW0402 系列通常以卷带（reel）形式供应，适配自动贴片机批量装配。订购时请确认完整的料号与包装代码，关注交期与认证（RoHS 等）要求。若需更高精度或更低温漂，可咨询替代的薄膜或金属膜产品。
总体而言，CRCW0402182KFKED 在空间受限且对成本敏感的高阻应用中表现良好，兼顾批量生产的可靠性与贴片装配效率。

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.
