From Feb 2018, HUASING Start offering higher spec doorknob capacitor from 60KVdc to 150KVdc, new available item please inquiry sales@hua-sing.com, following cross reference of HUASING dooknob capacitor to other brands. 

Alternative Replacement Cross Reference of High Voltage Doorknob Capacitor from Vishay, Murata, TDK, AVX

 

High Voltage Ceramic Capacitor Screw Terminal Type, also called “High Voltage Doorknob Capacitor”, is an industry grade electronic component.The well known brands are American company Vishay, AVX, and Japanese player Murata and TDK. These type of ceramic capacitors wildly use in X-ray generator, digital radiography, non destructive testing, laser and plasma equipment, Tesla Coil, Marx generator and many more. Since the entire high voltage machine market is decline. Major player gradually quit this market and leading doorknob capacitor “hard to find” item. End customer seeking for replacement solution for continue their existing running project and need technical support for new product development.

Murata is first company to release EOL notice for HV doorknob capacitor (DHS series, white color)In mid 2018.AVX also announce will not any more in position of production of doorknob capacitor (HP/HW/HD/HE series, use red color epoxy resin) in October 2018. Vishay and TDK is the only two major brand still in production, but lead time always keeping up to 18 weeks and more, and seldom to accept custom specification production order.Due to high cost they are not economic option for mass production especially in BRICS countries like Brazil, Russia, India, which in need of economic and reliable doorknob capacitor to produce various model high power Medical X-ray machine and airport inspection machine. HVCA brand also call Dean Technology CKE from U.S.A, this brand seems just OEM item. Their product can be found from their own HV distribution channel.

HUASING Capacitor from Southern China, is professional manufacturer of high voltage doorknob capacitor, with nearlly 10 years experience as alternative and replacement solution to above mention American and Japanese brand capacitor.
HUASING already earning good fame by close cooperation with lots Fortune 500 company like GE, PHILIPS, NIKON, KONICA Minolta and many more. 

HUASING brand High voltage doorknob capacitor also have following unique advantage:

1).
HUASING Capacitor is only manufacturer in mass production of 100kv and 150kv doorknob capacitor. While “well known” brand only present up to 50kv.

2).
HUASING Capacitor control with whole production process, from powder making, ceramic disc, to soldering assembly, and finally epoxy encapsulation. The “well known” brand always announce they are hardly to purchase the raw material, which is rare-earth element and strictly controlled by major develop country. Outsource raw material cause well known brand in higher product cost and result in long production lead time.

3).
HUASING Capacitor open to custom production, available wide range spec from 10kv to 150kv, capacitance from 100pf to 15000pf. low custom production MOQ, which is essential for new project development.Following listing full spec for HUASING Capacitor as alternative replacement and cross reference to Vishay, TDK, Murata, AVX, HUASING:
