TCC0402COG220F500AT是三环电子(CCTC)推出的一款高精度、高稳定性贴片多层陶瓷电容(MLCC),采用0402(1005)小型化封装,专为对容值精度、温度稳定性要求严苛的高频/精密电路设计,广泛适配消费电子、汽车电子、工业控制等领域的量产需求。
该产品属于C0G(NP0)类MLCC,是MLCC中温度系数最稳定、精度最高的品类之一,核心定位为“高频精密电路的基准电容元件”。不同于X7R/X5R等铁电介质电容(容值随温度、电压变化明显),C0G类采用顺电体陶瓷介质,容值特性不受环境温度、工作电压(额定范围内)影响,适合对信号稳定性要求极高的场景。
产品基本属性清晰:由三环电子(CCTC)原厂生产,符合RoHS 2.0、REACH等环保标准,无铅焊接兼容,可直接用于各类高密度PCB设计。
TCC0402COG220F500AT的关键参数经过严格校准,满足工业级及消费电子的高精度要求,具体如下:
参数项 规格值 说明 标称容值 22pF 代码“220”表示22×10⁰ pF 容值精度 ±1% 精度代码“F”对应国际通用±1%标准 额定直流电压(VR) 50V 代码“500”表示50V(无额外后缀为直流) 温度系数 C0G(NP0) 温度范围-55℃~+125℃,容值变化≤±30ppm/℃ 损耗角正切(tanδ) ≤0.15%(1kHz,25℃) 低损耗特性,减少高频信号能量损耗 工作温度范围 -55℃~+125℃ 宽温适应性,覆盖汽车、工业场景需求注:参数均为典型值,具体以原厂 datasheet 为准。
采用0402(英制)/1005(公制) 贴片封装,尺寸仅为1.0mm×0.5mm×0.5mm(长×宽×高),大幅节省PCB空间,适配智能手机、智能穿戴、小型化通信模块等高密度设计需求。封装引脚采用镍钯金(NiPdAu)镀层,焊接兼容性强,支持回流焊、波峰焊等常规工艺,焊点可靠性达汽车级标准(符合IATF16949要求)。
TCC0402COG220F500AT的高精度、宽温稳定特性,使其成为以下场景的核心元件:
三环电子(CCTC)是国内MLCC领域的龙头企业之一,产品通过以下认证与保障:
综上,TCC0402COG220F500AT凭借高精度、宽温稳定、小型化等核心优势,成为高频精密电路的理想选择,适配多领域量产需求,是本土客户替代进口高端MLCC的优质方案。

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.
