Atc porcelain chip rf vhf caps capacitors type 100C 1%
Here is the 100C Series Brochure: http:// /products/100c.asp

Imagine what Dad paid for this bunch of super-precise 1% tolerance (Code F) monster caps! Don't believe? Just give ATC a call and get a quote on a set of ten values in 1% tolerance of the 100C series...and be prepared to choke when they answer!
These are pure porcelain ultra-high-Q RF Power caps measuring a whopping quarter inch square! Dad says there are applications in VHF Power Generators, Linear Amplifiers, Laser Power Supplies, Antenna Tuners and all kinds of Resonating and Matching Networks for RF Plasma Generators.
ATTENTION AUDIOPHILE TUBE EXPERIMENTERS AND ULTRA-QUALITY SOUND AFFECTIONADOS:
THESE CAPACITORS WERE DEVELOPED FOR RUGGED MILITARY USE AT VHF AND UHF RADIO FREQUENCIES SO THEIR SALIENT CHARACTERISTICS MAKE THEM ABSOLUTELY PERFECT FOR HIGH-IMPEDANCE TUBE AUDIO WORK. IF YOU THINK POLYPROPYLENE, P.E.T. AND VIRGIN TEFLON CAPACITORS HAVE GREAT SONIC TRANSPARENCY, TRY PURE PORCELAIN! THE SUPER-LOW SERIES INDUCTANCE OF THESE ABSOLUTELY PURE CAPACITANCE ELEMENTS IS VIRTUALLY UNMEASURABLE AND COMPLETELY IGNORABLE FOR ALL AUDIO FREQUENCIES. THEIR SELF-RESONANT FREQUENCIES ARE SO FAR ABOVE THE AUDIO RANGE (AND FULLY SPECIFIED FOR EVERY CAPACITOR VALUE, BY THE WAY) THAT "PARASITIC INDUCTANCE" IS SIMPLY NOT PART OF THE AUDIO FREQUENCY DESIGN EQUATION WHEN PORCELAIN DIELECTRIC CAPS ARE USED.
YES, THE CAP VALUES HERE ARE SMALL BUT REMEMBER: YOU CAN PUT THESE IN PARALLEL REAL EASILY AND JUST ADD UP THE VALUES TO WHATEVER YOU NEED! THESE ARE ULTRA-PRECISION 1% TOLERANCE PARTS, TOO! TUBE CIRCUITS ARE TYPICALLY HIGHER-IMPEDANCE ANYWAY, SO SMALLER VALUES ARE OFTEN USED. THE VOLTAGE RATINGS ARE HIGH, 500VDC AND 1000VDC, SO THEY'LL WORK GREAT IN TUBE ENVIRONMENTS.
THE PORCELAIN DIELECTRIC IS FAR MORE TEMPERATURE STABLE THAN EVEN THE MOST EXOTIC POLYMER FILMS AND YOU CANNOT BEAT THESE CAPS FOR ULTRA-LOW IMPEDANCE, ESR AND DISSIPATION FACTOR, QUALITIES THAT ARE ESSENTIAL FOR SONIC ACCURACY AND TRANSPARENCY. FINALLY, THESE ARE SOME OF THE MOST PHYSICALLY RUGGED CAPS YOU'LL EVER FIND. DAD SAYS HE'S SEEN THEM WORK PERFECTLY RIGHT UP TO THE END IN TEMPERATURE-TESTING OVENS SET SO HOT THAT THE PARTS ACTUALLY UNSOLDERED THEMSELVES AND FELL OFF THE BOARD! WHEN THINGS COOLED DOWN, THE VERY SAME PARTS WERE SIMPLY RE-SOLDERED INTO THE CIRCUIT AND WORKED FLAWLESSLY! THAT'S PORCELAIN, BABY!
