TCC0402COG131J500AT是三环电子(CCTC) 推出的高频高稳定型贴片多层陶瓷电容(MLCC),针对温度稳定性、信号损耗要求严苛的电路设计,采用0402小型化封装,具备容值精度高、电压裕量充足等特点,广泛适配消费电子、射频通信、汽车电子等领域的小型化高密度电路。
该产品属于三环TCC系列高频MLCC,核心定位为精密信号处理与高频电路的稳定电容元件:
容值采用三位数字标识法:前两位“13”为有效数字,第三位“1”表示10的1次方,即13×10¹=130pF;精度标识“J”对应±5%,在-55℃~125℃范围内,容值偏差仍可控制在±0.05pF以内(典型值),满足精密电路对容值一致性的要求。
C0G是MLCC中温度稳定性最优的系列,温度系数≤±30ppm/℃(温度每变化1℃,容值变化不超过30×10⁻⁶),且损耗角正切(tanδ)≤0.15%(1kHz/1Vrms条件下),远低于X7R等系列,适合高频信号传输时减少能量损耗。
额定电压为直流50V,实际应用建议降额至40V以内(80%降额),可有效延长寿命;产品通过三环内部高温寿命测试(125℃/50V,1000小时),失效率低于0.1%,满足工业级可靠性要求。
0402封装是小型化设备主流封装,尺寸小巧(1.0mm×0.5mm),可显著提升PCB元件密度,适配智能手表、蓝牙耳机等便携设备的高密度设计。
三环电子(CCTC)是国内MLCC领先制造商,拥有20余年经验,产品通过ISO9001、IATF16949(汽车电子)认证,TCC系列经过温度循环、湿度老化、机械振动等严格测试,可满足工业级、消费级、汽车级多领域需求,为电路设计提供稳定可靠的电容解决方案。

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.
