TDK作为全球电子元器件领域的核心供应商,其CGA系列MLCC以高可靠性、宽温特性及紧凑封装著称。CGA2B2X8R2A102KT0Y0M是一款针对中高压、宽温场景优化的贴片电容,核心参数匹配1nF/100V/±10%/X8R,适用于工业控制、汽车电子及通信设备等高密度电路设计。
该型号编码对应明确的技术指标,各部分释义如下:
核心参数汇总:容值1nF、精度±10%、额定电压100V、温度范围-55℃~150℃、封装0402、非极性。
X8R温度系数是该产品的核心优势。不同于普通陶瓷电容的温度漂移,CGA2B2X8R2A102KT0Y0M在-55℃至150℃的极端温度范围内,容量变化始终控制在±15%以内,可满足汽车发动机舱(最高125℃)、工业高温传感器(150℃以下)等场景的持续稳定工作需求。
100V额定电压覆盖了多数中高压电路的需求,如工业PLC的电源滤波、汽车动力系统的信号耦合等。实际应用中建议遵循80%电压降额原则(即工作电压≤80V),可进一步提升长期可靠性,避免过压导致的电容老化或击穿。
0402封装尺寸仅1.0×0.5mm,厚度约0.5mm,是高密度PCB设计的理想选择。例如,在5G小基站的射频前端模块中,该电容可与其他器件紧凑布局,有效减少电路体积,提升设备集成度。
MLCC的固有特性使其具备低等效串联电阻(ESR)和低等效串联电感(ESL),CGA2B2X8R2A102KT0Y0M在1MHz频率下ESR可低至数毫欧,适合高速数字电路的信号滤波、射频电路的耦合/去耦,避免信号衰减或噪声干扰。
该产品的性能匹配多领域需求,核心应用场景包括:
TDK采用先进的陶瓷材料配方及多层叠层工艺,确保电容在温度循环(-55℃150℃,循环次数≥1000次)、振动(102000Hz,加速度2g)等严苛测试中性能稳定,符合IATF16949(汽车级)及工业级可靠性标准。
产品无铅无镉,符合欧盟RoHS 2.0及中国RoHS要求,适配全球市场的环保法规,降低客户的合规风险。
综上,TDK CGA2B2X8R2A102KT0Y0M是一款兼顾宽温稳定性、中高压耐受能力及小体积集成的MLCC,可有效解决工业、汽车及通信领域的高密度电路设计需求,是可靠性与性价比兼具的选择。

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.
