国内众多高压电源厂家(医疗,探伤,无损检测,静电, 喷涂等)曾广泛使用日本Murata(村田制作所)的高压陶瓷电容,村田高压电容无论在极限耐压水平,高频耐受性,容量稳定性等指标都远超中国和他国家同类型产品,但村田公司在2018年秋天决定整体停产高压陶瓷电容类目。
赫威斯电容(HVC Capacitor)在2018年设立定制生产线,作为替换Murata日本村田的高压引线型陶瓷电容和高压螺栓型陶瓷电容(俗称“门拧手”型电容 Doorknob Capacitors),涉及的村田型号的系列为DHR / DHS / DHK / DHB / DHC,电压从最低的2KV,3KV,6KV(中高压)10KV,12KV,15KV(高压)20KV to 50KV(超高压,螺栓型)。18年秋天至今赫威斯电容已经成功被世界五百强企业认可,如美国强生,瑞典ABB, 通用德国,通用医疗印度,尼康,柯尼卡.美能达等,另外众多美国纳斯达克上市医疗设备品牌和日本企业以及部分欧洲军工企业采均采用赫威斯电容作为村田的替代品。
村田公司在18年发布的高压电容全线停产通知内提到:高压机器设备市场正在不断萎缩,村田在该产品上未能盈利。事实上,我们知道村田不但停产了高压陶瓷电容,2017到2018年度,也停产了用于消费电子的通用型MLCC,此两类型的陶瓷电容采用十分类似的陶瓷介电材质,例如同样以SrTiO3和BaTiO2为基础材料的Y5U,X7R,NPO等。笔者认为村田处于商业考量,将相同的资源投放在毛利更高更有前景的电动车用MLCC市场而已。
村田电容是多层陶瓷电容(MLCC)的是全球市占率第一的品牌,同时也是高压陶瓷电容第一占有率和最知名品牌,该品牌主要销售市场在西欧,北美以及日本本土。HVC公司获释村田许多现有的终端客户都在着急寻找合适的村田高压电容的替换品,替换者必须和村田电容的表现同样优秀,外形尺寸,引脚距离等细节最好完全匹配,且最好不要修改原有PCB电路板,而且很多客户的产品面临升级换代,也非常需要元器件升级方面的技术支援。
HVC电容(赫威斯电容)是村田高压陶瓷电容的理想替代品牌。HVC电容提供十分广泛的产品序列,从1KV至100KV的高压电容。市面上仅有美国AVX公司也提供100KV高压电容,(据外电报导,AVX在2018.10月也宣布退出高压螺栓型陶瓷电容市场,即已经停产100KV产品)HVC电容有很多替换VISHAY,Murata,AVX和TDK高压陶瓷电容的成功案例。HVC电容的终端客户主要分布在X射线,CT, MRI , NDT(无损检测),等离子发生器,激光设备,特斯拉线圈,马克思发生器(高频高压脉冲),电子电力设备,以及涉及军工方面的应用,这些客户群体跟村田高压电容的客户群体基本一致。
作为理想的替换者,HVC电容还拥有以下突出优势:
1、HVC电容拥有自主研发的N4700级的陶瓷介质,此种材质广泛应用在高耐压水平要求,低损耗,高频耐受特性要求特别高的场合,N4700材质村田电容的材质标识码为”ZM”,而Vishay公司一般标识为”T3M”,其实都指的是N4700材质,HVC拥有自主专利版本的N4700材质。
2、HVC电容提供电路技术咨询,以及初级的线路板分析服务,以确保终端客户能够正确选型。这需要供应商有专业的电子元器件知识,以及丰富的实际应用经验。正确选型对于项目的成功至关重要,这也称为“DESIGN-IN”服务。
3、HVC电容针对客户的PCB空间,提供大比例的客户定制化生产,例如电容的直径,特殊的电容量,引线脚距离,和其他细节等等。
4、在大多数情况下,采用HVC电容作为替换,意味着降低采购成本,以及生产周期的大幅度缩减,HVC电容产品的交货期1kv-6kv为3到5天,常规10kv-30kv产品为2-3周时间,定制产品一般需要3周时间;螺栓型产品方面,一般是4周,定制型号为6到8周。
5、HVC电容已建立成熟的国际分销网络,授权分销商分布在德国,法国,英国,美国,意大利,俄罗斯,印度,韩国,日本,马来西亚,新加坡等等。国际代理商提供物流,仓储,库存缓冲,在地化客户服务,如商业拜访,符合当地商务习惯的优惠的付款条件,及其他的增值服务。终端客户在当地就能购买到HVC(赫威斯电容)的产品,跟在当地购买一样。HVC电容中国市场指定代理商为苏州三利特电子有限公司。
6、HVC公司支援客户新产品开发和现有产品的升级换代,即提供更高耐压的电压,更高的频率耐受性的定制电容。
