CGA0201C0G120J500ET是芯声(HRE)推出的贴片多层陶瓷电容(MLCC),型号字符清晰对应产品核心特性:
该产品定位为小体积、高稳定、低压高频应用的基础电容,适配高密度PCB设计需求,尤其适合对集成度和性能一致性要求较高的便携式、通信类设备。
标称容值12pF,精度±5%(J档),满足多数通用电路对容值一致性的要求(如无需亚%级精度的匹配电路)。实际应用中,容值偏差在±0.6pF范围内,可覆盖晶振负载、信号耦合等场景的基础需求。
直流工作电压50V,可直接适配3.3V、5V等常见低压系统;若用于交流电路,需遵循交流峰值电压≤额定电压70% 的降额原则(即交流峰值≤35V),避免过压失效。
C0G类电容损耗角正切(tanδ)典型值≤0.15%(1kHz/25℃),高频下(如1GHz)损耗仍保持低水平;同时0201封装寄生电感约0.5nH,可减少高频信号的能量损耗,适合射频前端电路。
0201封装是目前小型化MLCC的主流规格之一,物理特性如下:
C0G(NP0)是陶瓷电容中温度稳定性最优的类别,核心优势包括:
-55℃至+125℃温区内,容值变化≤±30ppm/℃(即容值波动≤0.036%),远优于X7R(±15%)等中温稳定型电容,适合宽温环境应用(如工业控制设备)。
无明显容值随直流偏置变化的现象(X7R等电容在偏置下容值会下降10%~30%),适合需要稳定容值的电源滤波、信号耦合电路。
高频下(如2.4GHz蓝牙频段)容值变化极小,寄生电容/电感低,可有效提升射频信号的传输效率。
该产品因体积小、稳定、高频性能好,广泛应用于以下场景:
芯声(HRE)作为专业MLCC制造商,该产品满足多项可靠性与合规要求:
CGA0201C0G120J500ET凭借小体积、高稳定、宽温适配等优势,成为低压高频电路中基础电容的优选方案,尤其适合对集成度和性能一致性要求较高的便携式、通信类设备,可有效平衡成本与性能需求。

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.
