150 µF, 20 V, 35 mOhm ESR — bulk decoupling with low loss
The low ESR keeps self-heating under ripple current in check — for a 2 A RMS ripple, the internal temperature rise stays under 10 °C, which matters when the cap is packed next to a hot POL regulator. The 35 mOhm ESR is the key parametric for switching converters: it sets the ripple voltage at the output and the I²R loss in the cap. At 150 µF and 20 V, this part fits 12 V bus decoupling, 5 V output filtering, and hold-up capacitor banks where the ESR dominates the voltage dip during load transients.
Full military temperature range — avionics and downhole ready
The molded case construction (type: Molded) provides mechanical stability across the range without the moisture sensitivity of some polymer electrolytics. The 2917 (7343 Metric) case, size code E, measures 7.30 mm x 4.30 mm with a seated height of 4.30 mm. Surface-mount reflow profile follows standard tantalum recommendations — no special bake required if the tape is used within the shelf life.
