0402B101K500CT是华新科(Walsin) 推出的一款片式多层陶瓷电容(MLCC),型号各段含义清晰:
该产品定位为常规中温稳定型MLCC,适配多数电子设备的基础滤波、耦合需求。
标称容值100pF,精度±10%,满足90%以上常规电路的容值误差要求(如电源滤波、信号耦合),无需高精度校准即可稳定工作。
额定直流电压50V,实际使用需遵循80%~90%降额原则(即工作电压≤45V),可避免介质老化加速,延长产品寿命。
温度系数为X7R,是MLCC中经典的中温稳定介质:
典型损耗角正切(tanδ)≤2%(测试条件:1kHz、25℃),信号传输过程中能量损耗低,适配音频、射频辅助滤波等场景。
0402封装体积小巧(长1.0mm×宽0.5mm×厚≈0.5mm),可大幅节省PCB布局空间,适配智能穿戴、小型通信模块等高密度设计。
采用多层陶瓷介质叠层结构:
支持回流焊、波峰焊等常规表面贴装工艺,焊接温度曲线需符合华新科推荐(峰值温度230℃~245℃,回流时间≤60秒),避免热冲击导致性能下降。
结合参数特性,该产品适用于以下场景:
工作温度-55℃~+125℃,湿度≤95%(非凝露),可适应工业现场、户外设备等宽温湿度变化。
额定条件下寿命达数万小时,长期使用中容值、损耗变化极小,符合IEC 60384-1国际标准。
片式封装抗振动性能优异(振动频率10Hz2000Hz,加速度10g20g),可承受运输、安装中的机械冲击。
该产品凭借稳定的X7R特性、小体积封装与高可靠性,成为电子设备基础电路的主流选型之一。

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.
