TCC0402COG2R7B500AT 贴片多层陶瓷电容（MLCC）产品概述
一、产品定位与核心优势
本型号为三环电子（CCTC）推出的高频精密型MLCC，针对小型化、宽温稳定、低损耗的电路设计需求，核心聚焦三大差异化优势：
- C0G容值超稳定：温度系数满足NP0标准，宽温下容值漂移极小；
- 0402超小封装：适配高密度PCB布局，满足电子设备轻薄化趋势；
- 50V中压覆盖：兼顾精密电路的电压需求与小型化限制，是通信、消费电子领域的通用型精密电容。
二、关键参数详细解析
参数项 具体指标 说明 标称容值 2.7pF C0G系列典型精密容值，误差≤±0.1%（典型） 额定电压 50V（直流） 实际应用需75%降额（≤37.5V）延长寿命 温度系数 C0G（NP0） ±30ppm/℃以内，-55℃~+125℃容值变化≤0.03% 封装尺寸 0402英制（公制1005） 1.0mm×0.5mm×0.5mm，引脚间距0.25mm 介质损耗（tanδ） ≤0.0001（1kHz/25℃） 低损耗特性减少高频信号衰减 绝缘电阻 ≥10¹⁰Ω（25℃/50V） 高绝缘性避免漏电流干扰三、封装结构与工艺特点
本产品采用多层陶瓷叠层工艺：
- 介质层：C0G低损耗陶瓷，无压电效应，避免容值随电压/温度漂移；
- 电极层：镍基内电极，与介质层兼容性强，高温烧结后形成一体化结构；
- 端电极：三层结构（镍→锡→铅或无铅锡），确保回流焊时的润湿性与机械强度，抗热冲击性能符合IPC J-STD-001标准；
- 封装设计：0402封装的紧凑体积，可实现每平方厘米PCB贴装≥1000个电容，适配高密度电路设计。
四、典型应用场景
因C0G的低损耗、宽温稳定特性，本型号广泛用于对容值精度要求极高的电路：
- 高频通信：5G基站射频前端的带通滤波、耦合电路；WiFi6模块的天线匹配网络（减少信号衰减）；
- 精密仪器：示波器、信号发生器的振荡电路（保证信号频率精度）；医疗监护设备的传感器信号调理电路；
- 消费电子：智能手机射频收发器、时钟电路；智能手表无线充电接收端滤波（适配轻薄化需求）；
- 汽车电子：辅助驾驶毫米波雷达信号滤波、车身控制器时钟电路（-55℃~+125℃宽温适配汽车环境）。
五、可靠性与环境适应性
- 寿命表现：额定电压50V、125℃工作温度下，寿命≥10⁶小时（符合IEC 60384-14标准）；
- 环境耐受：可承受1000小时湿热试验（85℃/85%RH），绝缘电阻保持≥10¹⁰Ω；抗机械振动（10~2000Hz，1.5g加速度）与冲击（1000m/s²）性能符合汽车级要求；
- 焊接兼容性：支持铅锡与无铅回流焊工艺，焊接温度范围220℃~260℃，无气泡、虚焊等缺陷。
六、选型与替代参考
- 同品牌扩展：
- 更高精度：TCC0402COG2R7B500BT（误差±0.02%）；
- 更高电压：TCC0402COG2R7B100AT（100V额定电压）；
- 跨品牌替代：
- 村田：GRM1555C1H2R7CA01D（同参数）；
- TDK：C1005C0G2R7C500（同参数）；
- 选型注意：需根据实际工作电压降额（≥70%）、温度范围选择，避免超压/超温使用。
本型号作为三环CCTC的成熟精密MLCC，兼顾性能与成本，是小型化高频电路的可靠选择。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
