TCC0402X7R202K500AT是三环电子(CCTC) 推出的通用型贴片多层陶瓷电容(MLCC),核心参数明确:
产品采用多层陶瓷叠层工艺,体积小、容量稳定,适配大多数低压电路的滤波、耦合需求。
X7R是MLCC通用型温度系数的典型代表,-55℃至+125℃ 宽温范围内,容值波动≤±15%,无需额外温度补偿,可满足工业级、消费电子的宽温使用(如户外设备、车载辅助电路)。
0402封装体积仅1.0mm×0.5mm×0.5mm(典型高度),大幅节省PCB空间,适配手机、智能穿戴、物联网终端等对体积敏感的产品设计。
额定电压50V高于常见3.3V/5V/12V系统工作电压,实际应用留有余量(建议降额至40V内),降低击穿风险,延长寿命。
虽非高精度档位,但完全满足滤波、耦合等常规需求(如电源滤波、射频信号耦合),适合批量应用。
该产品凭借小体积、宽温稳定等特点,广泛用于:
三环电子对该产品管控严格:
实际工作电压≤40V(额定80%),延长寿命。
该产品是平衡性能、成本与体积的通用型MLCC,适配多领域电子设计需求。

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.
