TCC0603COG200J500CT是CCTC(三环电子) 推出的高性能贴片多层陶瓷电容(MLCC),专为对容值稳定性、高频特性要求严苛的电子电路设计。产品采用0603(英制)封装,核心参数匹配20pF容值、±5%精度、50V额定电压及C0G温度系数,可广泛应用于通信、工业控制、消费电子等领域的高频稳定场景。
该产品属于C0G系列(NP0类)MLCC,是针对温度稳定性、低损耗需求优化的陶瓷电容品类,核心属性如下:
标称容值为20pF,精度等级±5%(对应电容精度标识“J”档),批量生产一致性优异,可满足精密电路对容值准确性的要求。
额定直流电压为50V,交流场合需降额(交流峰值电压不超过50V),避免介质击穿。产品通过高温老化、电压应力测试,满足IEC 60384-14等MLCC可靠性标准。
C0G温度系数赋予产品高稳定性:在-55℃至+125℃工作范围内,容值变化率≤±30ppm/℃(约0.3%/10℃),几乎不受温度影响,适合对容值敏感的电路。
采用低损耗陶瓷介质,1kHz至1GHz频段内损耗角正切(tanδ)≤0.001(1kHz时),高频下仍保持低损耗,适配射频、微波电路的耦合、滤波需求。
体积小巧(1.6mm×0.8mm),可显著节省PCB空间,适合高密度贴片组装(如智能手机、路由器等小型化设备)。封装机械强度满足SMT回流焊、无铅波峰焊的应力要求,焊接可靠性高。
采用多层陶瓷介质+内电极+外电极叠层设计:
因C0G的高稳定性与低损耗特性,该产品适用于以下场景:
CCTC作为国内MLCC主流厂商,产品通过以下测试:
TCC0603COG200J500CT是一款兼顾稳定性、高频特性与小型化的MLCC产品,C0G温度系数使其在宽温范围内保持容值稳定,0603封装适配高密度组装,广泛覆盖通信、工业、消费电子等领域的高频精密电路需求。CCTC的品牌可靠性与环保认证,进一步提升了产品的市场适用性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
