Excessive reliability ceramic capacitors are stacked

‘DSCC 25007 Mini BME Stacks’ mix a number of 2220-size capacitors with X7R traits (from its MIL-PRF-32535 vary) utilizing a legged lead-frame, have base steel electrodes, and are 100% Group A examined.

100% Group A and Group B testing is on the market for demanding designs with T-level necessities, added Kyocera.

They’re “designed to fulfill the necessity for compact and light-weight high-CV SMT capacitors in high-reliability navy, aerospace and area purposes”, it mentioned.

The components are made in a DLA-approved, MIL-PRF-32535 certified facility and are traceable.  and subjected to rigorous testing to make sure excessive reliability and efficiency in excessive circumstances and harsh environments — particularly 100% Group A testing or

The primary components releases have two capacitors stacked horizontally, and both have J-leads with two massive toes that largely match the solder footprint of a 2220 SMD ceramic capacitor (see photograph), or two massive ‘L’ toes, or 4 smaller toes in J or L configuration.

All toes are tin-Pb plated.

Measurement is 7.5mm excessive from the underside of the toes to the highest of that stack, 5.4mm extensive, and seven.2mm lengthy within the shorter (J-lead) variations.

There are 9 capacitance values between 8.2 and 47µF (±20% tolerance).

Operation is throughout -55 to +125°C and as much as 25, 50 or 100V. Later components might differ.

Within the pipeline are components with three chips stacked horizontally, and components with three, 5 or 10 chips stacked vertically.

The information sheet could be discovered right here – see web page 9 for the deliberate stacks as much as 10 lengthy.

Use is foreseen in energy provide enter and output filtering.

AVX has been stacking capacitors for a very long time – right here in 2008, for instance
