TCC0805COG220J500BT是三环电子(CCTC) 推出的一款贴片多层陶瓷电容(MLCC),针对高频精密电路设计。其命名遵循行业通用规则,各段含义解析如下:
该产品属于温度补偿型MLCC,核心优势在于容值稳定性、低损耗特性,适配高频/精密电路需求。
容值标称22pF,精度±5%(J级),在-55℃~125℃宽温范围内,容值变化率≤±30ppm/℃,无明显老化现象(C0G材质固有特性),满足精密电路对容值一致性的要求。
直流额定电压50V,峰值电压(浪涌电压)设计为75V(1.5倍额定电压),可承受短时间过压冲击;1kHz/1Vrms条件下交流电压额定值约35Vrms,适配小功率电源滤波场景。
封装尺寸0805(2.0×1.2×0.8mm),无引脚贴片结构,适配标准SMT产线;机械特性满足:振动(10~2000Hz,加速度10g)、冲击(1000g/0.5ms)、PCB弯曲(≤2mm),抗环境应力能力强。
采用温度补偿型低介电常数陶瓷(主要成分为钛酸钡基复合材料),介电常数εr≈30~60,容值随电压、直流偏置变化可忽略(≤0.1%),区别于高介电常数的X7R/X5R材质(容值随偏置下降明显)。
该产品因低损耗、高稳定特性,广泛应用于以下领域:
三环电子是国内MLCC行业头部企业,拥有20余年生产经验,产能稳定(月产能超10亿只),通过ISO9001、IATF16949(汽车级)、RoHS 2.0等认证。
产品经过全流程可靠性验证:
无铅无卤设计,适配欧盟REACH、美国加州65等环保法规;端电极与Sn-Pb、无铅焊料均兼容,支持回流焊、波峰焊(需优化参数)。
该产品凭借稳定的性能、可靠的工艺及广泛的适配性,成为高频精密电路的优选MLCC方案。

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.
