TCC0805COG471J501BT是三环电子(CCTC)推出的一款中高压精密贴片多层陶瓷电容(MLCC),采用0805(英制2012)封装,核心参数匹配高频、精密及中高压应用场景,是工业控制、通信设备等领域的常用基础元件。
该型号为三环电子常规系列MLCC,核心标识明确:
TCC0805COG471J501BT的关键参数聚焦温度稳定性、容值精度及电压耐受,具体如下:
采用C0G型低温烧结陶瓷,其成分以钛酸钡为基础,掺杂稳定元素,实现极低温度系数、低损耗,且无压电效应,适合高频电路(如射频、微波)。
基于其参数特性,TCC0805COG471J501BT主要应用于以下领域:
实际工作电压建议不超过额定电压的80%(即400V),避免长期高压导致陶瓷介质老化,延长产品寿命。
MLCC为静电敏感元件(ESD等级通常为Class 1),操作时需佩戴防静电手环,工作台接地,避免静电击穿内部电极。
常温干燥环境(温度1535℃,湿度40%60%),存储周期不超过12个月;开封后未使用的元件需密封保存,避免受潮影响焊接性能。
三环电子(CCTC)是国内MLCC领域的主流厂商,该型号符合以下标准:

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.
