High Energy Quick Discharge Capacitors
WM - Welded Metal
Largest of our Maxwell selection, the welded metal cans have two terminal variations. Two isolated terminals as shown and the lowest inductance models with single terminal case ground. Allow for extra weight in your design. These beauties are HEAVY Duty.
SP - Plastic Case
M-S/S - Stainless Steel Metal Case
Stainless steel metal case capacitors are impervious to harsh environments. Terminals on each end. Valve allows access to cavity.
C - Cylindrical Metal
Cylindrical metal case capacitors with light weight, unique design just right for compact applications. Terminals on top end.
P - Plastic Case
Plastic case single ended capacitors with compact design for extremely low inductance, fast rise time applications. Many uses in medical and "RF" environments.
D - Double Ended Plastic Case
Double ended plastic case capacitors have terminals on opposing ends. Plastic compact case designed for extremely low inductance, fast rise time applications.
M - Metal Case
Metal case caps have drawn metal can, double roll seams. High capacity / voltage ratio in small package.

All Maxwell prices set below factory cost. Further discounts may be available for large quantities.

APPLICATIONS: Cardiac Defibrillators, space based lasers, inertial confinement fusion experiments, hard rock mining, flashlamp drivers, lasers, RF linac, arc lamp, plasma deposition, sputtering and so on! All new unless otherwise marked.
