TCC0603COG250G500CT是三环电子(CCTC) 推出的Class 1型贴片多层陶瓷电容(MLCC),专为对容值稳定性、精度要求严格的电子电路设计。核心参数如下:
型号命名逻辑清晰:“TCC”为三环品牌标识,“0603”明确封装,“COG”代表温度系数,“250”表示25×10⁰pF(25pF),“G”对应±2%精度,“500”为50V额定电压,“CT”关联封装细节与包装形式。
高精度与稳定容值
容值精度达±2%,远高于常规MLCC的±5%/±10%标准,可满足滤波器、振荡器等对容值匹配性要求苛刻的电路。搭配C0G温度系数,-55℃~125℃范围内容值漂移仅±30ppm/℃,温度稳定性远优于Class 2介质(如X7R/Y5V),不受环境温度波动影响。
低损耗与高频适配性
C0G介质的介质损耗角正切(tanδ)典型值≤0.15%(1kHz条件下),高频电路中无额外发热,适合射频(RF)、微波等场景,信号传输损耗小。
紧凑封装与贴装兼容
0603封装体积小巧,符合电子设备“小型化、高密度”趋势,与主流SMT生产线兼容,支持自动化批量生产,效率高。
额定电压与功率适配
50V额定直流电压覆盖大多数低压电路需求(如消费电子、通信设备信号处理),无需额外降额即可稳定工作,可靠性有保障。
该产品的性能特性使其适用于对容值稳定性、精度、高频性能要求较高的领域,典型应用包括:
三环工艺保障
三环电子是国内MLCC主流厂商,拥有成熟的多层叠片工艺,介质层均匀性好,电极与介质结合紧密,产品一致性高,批量生产不良率低。
MLCC固有优势
无极性设计(无需区分正负极)、体积小、容量范围宽(Class 1覆盖1pF~100nF)、寿命长(陶瓷介质稳定无老化),相比电解电容更适合高频、小型化场景。
环境适应性
工作温度范围宽(-55℃~125℃),耐湿性好,符合RoHS环保标准,适配绿色电子设计趋势。
该产品凭借高精度、高稳定性与紧凑封装,成为射频、工业控制等领域的高性价比选择,可有效满足现代电子设备的小型化与性能需求。

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.
