Frequently Asked Questions
What capacitance and voltage rating does the EEE-TC1V391UP provide for bulk decoupling?
The EEE-TC1V391UP offers 390 µF capacitance at a 35 V rated voltage. This combination of high capacitance and voltage rating makes it suitable for the output bulk decoupling stage of 24 V and 28 V switch-mode power supplies where large energy storage buffers load transients and smooths ripple below acceptable limits.
How does the physical size of the EEE-TC1V391UP compare to other 390 µF SMD electrolytic capacitors?
The EEE-TC1V391UP measures 10 mm diameter by 10.2 mm height, placing it in a mid-sized radial SMD footprint. Competing 390 µF 35 V capacitors often require taller 12.5 mm or 16 mm can heights to achieve the same capacitance; Panasonic's TC series achieves 10.2 mm height through optimized electrode winding technology.
Which power supply designs benefit most from substituting the EEE-TC1V391UP for a through-hole electrolytic?
Designs migrating from through-hole to fully automated SMT assembly benefit most: the EEE-TC1V391UP is supplied in tape-and-reel format and fits a 10 mm SMD land pattern. DC-DC converters operating at frequencies up to 100 kHz with 5 A output currents see reduced ESR and improved ripple attenuation compared to standard through-hole 390 µF 35 V electrolytic alternatives.
What operating temperature range does the EEE-TC1V391UP support in industrial applications?
Panasonic's EEE-TC1V391UP is rated for an operating temperature range of -55°C to +105°C, which satisfies industrial and automotive-adjacent environmental requirements. The 105°C upper limit allows placement near heat sources on a PCB, extending the capacitor's service life in thermally demanding applications such as motor drive inverters and industrial power converters.
