CGA0402X5R226M6R3GT是芯声电子(HRE) 推出的通用型贴片多层陶瓷电容(MLCC),属于小型化高密度封装系列。型号命名规则直接体现核心参数逻辑:
该产品专为小型化、低功耗电路设计,兼顾容量密度与环境适应性,是消费电子、IoT设备等领域的主流选型之一。
0402封装是当前最小的MLCC封装之一,体积仅为0603封装的40%左右,可显著缩小电路尺寸。22μF的容值在0402封装中属于高容量密度,解决了便携设备“小体积与大容量”的矛盾——例如智能手机PMIC输出滤波、智能手表心率传感器模块的储能需求,无需牺牲容量即可实现超薄布局。
X5R材质的温度特性(-55℃~+85℃,容量变化±15%)优于普通NPO材质的窄温范围,且容值漂移远小于Y5V等高压陶瓷电容。该特性使其可适配高低温交替环境(如车载小型传感器、户外IoT节点),避免因温度变化导致电路性能波动(如滤波效果减弱、信号耦合失真)。
MLCC无极性、无电解液,相比电解电容更耐振动冲击(振动频率202000Hz,加速度10g)。X5R材质的低损耗(tanδ≤5%)适合信号通路应用,不会因损耗发热影响电路稳定性;同时产品通过**高温存储(125℃×1000h)、温度循环(-55+85℃×1000次)** 等可靠性测试,满足工业级应用需求。
产品符合RoHS 2.0、REACH等环保标准,适配全球市场;封装兼容标准SMT(表面贴装)工艺,可用于自动贴片机(精度≥01005),实现大规模高效生产,降低客户制造成本。
实际工作电压建议不超过5V(6.3V×80%),避免过压导致电容击穿或容量衰减。若电路峰值电压接近6.3V,需并联小容量高压电容(如1μF/10V)进行保护。
X5R适用-55+85℃,若设备工作环境温度超过85℃(如车载高温区域),需更换X7R材质电容(-55+125℃);若温度低于-55℃(如航空航天),则需选用NP0材质。
X5R在85℃时容量会下降约15%,设计时需预留20%容值裕量(如滤波电路需22μF,则选型22μF以上),避免高温下滤波效果减弱。
0402封装焊接需注意:
芯声电子(HRE)是国内专注MLCC研发与生产的高新技术企业,产品通过ISO9001质量管理体系、IATF16949汽车级认证,批次一致性控制在±5%以内(优于行业平均水平)。CGA0402X5R226M6R3GT系列产品已实现大规模量产,供应稳定,可满足客户不同批量需求。
该产品凭借小型化、宽温稳定、高可靠性等优势,成为便携式设备与IoT领域的高性价比选型,可有效提升电路设计的紧凑性与稳定性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
