ERJ2RKF4642X 厚膜贴片电阻产品概述
一、产品核心定位与类型
ERJ2RKF4642X是松下（PANASONIC）推出的厚膜贴片电阻（SMD），属于小型化、高精度通用型功率电阻，核心定位为“高集成度电路中的常规分压、限流、偏置电阻”，兼顾性能与成本优势，可覆盖消费电子、工业控制等多领域应用。
二、关键电气参数详解
该电阻的电气参数明确且适配0402封装的典型场景，核心参数如下：
- 阻值：固定46.4kΩ，属于E96系列标准阻值（1%精度电阻的通用序列）；
- 精度：±1%，满足商业级至工业级电路的误差要求（如传感器信号调理、电源反馈电路）；
- 额定功率：100mW（0.1W），0402封装的常规功率，实际需遵循降额原则（如125℃时降额至70mW，155℃时降额至50mW，参考松下官方曲线）；
- 最大工作电压：100V，需同时满足“V≤√(P×R)≈68.1V”，避免过压；
- 温度系数（TCR）：±100ppm/℃，表示温度每变1℃，阻值变化±100×10⁻⁶（如155℃与25℃温差130℃时，阻值变化≈±603Ω），适配非超低温漂场景。
三、封装与物理特性
- 封装规格：0402（英制，对应公制1005：长1.0mm、宽0.5mm、厚≈0.3mm），主流小型化封装，适合高密度PCB布局；
- 工艺材料：厚膜工艺，以氧化铝陶瓷为基底，丝网印刷钌基电阻浆料烧结而成，电阻层与基底结合牢固，稳定性优于碳膜电阻；
- 焊接兼容：无引脚贴片设计，支持回流焊、波峰焊，焊接可靠性符合IPC-A-610标准。
四、环境适应性与可靠性
- 工作温度：-55℃+155℃，覆盖工业级（-40℃+85℃）及部分高温场景（如汽车发动机舱周边）；
- 长期可靠性：125℃下1000小时负载寿命试验显示，阻值变化≤±0.5%，电压变化≤±0.1%；
- 环保认证：符合RoHS 2.0（无铅）、REACH标准，部分批次通过AEC-Q200（汽车电子）认证。
五、典型应用场景
- 消费电子：智能手机/平板的电源管理电路（充电分压）、音频信号调理（耳机放大器偏置）；
- 工业控制：小型PLC输入输出接口、PT100温度传感器信号放大；
- 通信设备：小型基站/路由器射频前端（滤波器匹配电阻）；
- 汽车电子（非安全关键）：仪表盘背光电路、胎压传感器辅助分压。
六、品牌与供应保障
- 品牌优势：松下工艺成熟，批量阻值一致性好，偏差控制严格；
- 供应稳定：标准品供应周期2~4周，支持1000只起订及大批量采购；
- 技术支持：提供官方datasheet、降额曲线、焊接指导等资料。
总结
ERJ2RKF4642X是性能均衡的厚膜贴片电阻，以0402小型封装、±1%高精度、宽温范围为核心优势，适配多领域常规电路设计，是松下电阻系列的经典通用型号。

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.
