CGA1206X7R226K160NT是HRE芯声品牌推出的通用型贴片多层陶瓷电容(MLCC),型号各字符对应核心参数:
基础参数汇总:
项目 规格 容值 22μF 精度 ±10% 额定电压 16V(直流) 温度系数 X7R(-55℃~125℃) 封装 1206(3.2mm×1.6mm) 品牌 HRE芯声 环保认证 RoHS、REACH宽温下容值稳定
X7R介质是MLCC中“平衡容值与温漂”的主流选择:在-55℃~125℃范围内,容值变化不超过±15%,远优于Y5V介质(温漂可达±82%),适合户外设备、工业环境等宽温场景。
精度与成本兼顾
±10%精度满足90%以上常规电路需求(如电源滤波、信号耦合),相比±5%精度的电容成本降低约20%,适合批量应用。
封装可靠性高
1206封装采用无铅陶瓷-金属电极结构,焊接兼容性好(回流焊峰值温度230~250℃,时间≤30s),抗机械应力能力优于小封装(0603),适合振动环境(如车载二级电路)。
低压场景适配性强
16V额定电压覆盖5V/12V低压系统(如消费电子、小型工业电源),实际工作电压建议控制在12.8V以内(80%降额),可延长寿命至10万小时以上(25℃环境)。
消费电子领域
工业控制设备
车载二级电路
通信设备
温度适配
避免在125℃以上长期工作(如发动机舱),否则容值漂移会超差;低温-55℃以上无性能衰减。
高频场景限制
1206封装的寄生电感约1nH,适合中低频(<100MHz)应用;若需高频(>100MHz),建议选0603小封装。
焊接工艺
禁止手工焊接(易过热损坏陶瓷介质),需采用回流焊,温度曲线需符合MLCC标准(预热150180℃,峰值230250℃,过温时间≤30s)。
储存与开封
常温(25℃±5℃)、干燥(相对湿度≤60%)环境储存,开封后建议12个月内用完,避免吸潮导致焊接时“爆浆”。
HRE芯声是国内专注于MLCC研发生产的品牌,产品通过ISO9001质量认证,符合RoHS2.0、REACH SVHC标准;CGA系列针对中低端市场,兼顾性能与成本,批量采购交货周期稳定(通常7~15天),适合中小制造企业。
该产品是低压电路中“滤波、耦合、旁路”场景的高性价比选择,可替代同类进口品牌(如村田GRM188R61C226KA73D),降低采购成本30%左右。

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.
