The parts are surface-mount, and their vibration resistance “is achieved by four posts that come out of the base plate of the component and stabilise the can in the event of mechanical shocks and vibrations”, according to the company.
They have been added to the B40950 and B40910 series of capacitors, and are indicated by a ‘100’ suffix instead of the standard ‘000’ 5g versions.
B40950 types work across -55°C to +105°C, while B40910 capacitors push this to +150°C.
Voltage and capacity ratings span 25 to 80V and 1,100µF to 56µF .
Diameter is 10mm, and heights range across 10.2 to 16.8mm.
The polymer improves effective series resistance and ripple current capacity to 10 to 33mΩ. and 2.8 to 5.8A.
Depending in type, useful life is more than 4,000h at +125°C, or 10,000h at a +105°C for series B40950 – both at rated voltage and rated ripple current, to 30% of initial capacitance.
“The web-based AlCap Tool quickly and easily calculates accurate lifetime under application-specific conditions,” claimed TDK, which foresees use in vehicle power steering, dc-dc converters, cooling fans, water pumps, oil pumps and brakes, as well as GPUs, robots, e-bikes, e-scooters and power tools).
