ERJ2RKF5232X是松下(PANASONIC)推出的一款0402封装厚膜贴片电阻,针对小型化电子设备的高密度设计需求,兼顾稳定性能与成本优势,广泛应用于消费电子、工业控制等多领域场景。
该电阻属于通用型厚膜贴片电阻,核心参数明确匹配中小功率电路的阻值匹配、限流、偏置等功能需求:
52.3kΩ ±1%的规格兼具精准性与实用性:非整数阻值可直接匹配定制化电路(如传感器偏置、模拟信号调理),无需额外电阻组合;±1%精度无需校准即可实现稳定的电路性能,覆盖90%以上的常规应用场景。
100mW额定功率是0402封装厚膜电阻的标准配置,在25℃环境下可长期稳定工作。需注意温度降额:当环境温度超过70℃时,功率需按曲线降低(如125℃时降额至50mW),确保阻值稳定性与使用寿命。
±100ppm/℃的TCR是厚膜电阻的常规表现:温度每变化1℃,阻值变化±0.01%。以工作范围-55℃~+155℃计算,最大温差210℃时,阻值总变化约±2.1%,可满足工业控制、车载辅助电路等宽温需求。
0402封装兼容主流SMT工艺(回流焊、选择性波峰焊),贴装精度高;松下封装工艺确保引脚与PCB附着力符合IPC标准,可承受常规振动(10~2000Hz,1g)与冲击(1000m/s²,1ms)测试。
厚膜电阻采用丝网印刷+高温烧结工艺,膜层厚度(10~100μm)远厚于薄膜电阻,具备:
ERJ2RKF5232X以紧凑尺寸、稳定性能、宽温适应性为核心优势,适配小型化电子设备的高密度设计,同时兼顾成本与可靠性。其精确的52.3kΩ阻值可直接匹配定制化电路,减少误差累积,是消费电子、工业控制等领域中小功率电路的理想选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
